How do I do this equation -5y+22>42
Answer:
Step-by-step explanation:
To solve the equation -5y + 22 > 42, we'll isolate the variable y.
First, let's subtract 22 from both sides of the inequality to move the constant term to the right side:
-5y + 22 - 22 > 42 - 22
Simplifying, we have:
-5y > 20
Next, we'll divide both sides of the inequality by -5. However, note that when dividing by a negative number, the direction of the inequality sign flips. Thus, we have:
(-5y) / -5 < 20 / -5
Simplifying further:
y < -4
Therefore, the solution to the inequality -5y + 22 > 42 is y < -4.

Use C as the unknown constant.
what to do???
This is the general solution to the given differential equation, where C is the arbitrary constant.
general solution to the given differential equation, we can follow these steps:
Step 1: Put the problem in standard form:
Rearrange the equation to have the derivative term on the left side and the other terms on the right side:
dy/dx - x + x^2y = x^2 - x.
Step 2: Find the integrating factor:
The integrating factor, p(x), can be found by multiplying the coefficient of the y term by -1:
p(x) = -x^2.
Step 3: Rewrite the equation using the integrating factor:
Multiply both sides of the equation by the integrating factor, p(x):
-x^2(dy/dx) + x^3y = x^3 - x^2.
Step 4: Simplify the equation further:
Rearrange the equation to isolate the derivative term on one side:
x^2(dy/dx) + x^3y = x^3 - x^2.
Step 5: Apply the integrating factor:
The left side of the equation can be rewritten using the product rule:
d/dx (x^3y) = x^3 - x^2.
Step 6: Integrate both sides:
Integrating both sides of the equation with respect to x:
∫ d/dx (x^3y) dx = ∫ (x^3 - x^2) dx.
Integrating, we get:
x^3y = (1/4)x^4 - (1/3)x^3 + C,
where C is the unknown constant.
Step 7: Solve for y(x):
Divide both sides of the equation by x^3 to solve for y(x):
y = (1/4)x - (1/3) + C/x^3.

Problem Consider the (real-valued) function f:R 2→R defined by f(x,y)={0x2+y2x3} for (x,y)=(0,0), for (x,y)=(0,0)
(a) Prove that the partial derivatives D1 f:=∂x∂ and D2 f:=∂y∂f are bounded in R2. (Actually, f is continuous! Why?) (b) Let v=(v1,v2)∈R2 be a unit vector. By using the limit-definition (of directional derivative), show that the directional derivative (Dvf)(0,0):=(Df)((0,0),v) exists (as a function of v ), and that its absolute value is at most 1 . [Actually, by using the same argument one can (easily) show that f is Gâteaux differentiable at the origin (0,0).] (c) Let γ:R→R2 be a differentiable function [that is, γ is a differentiable curve in the plane R2] which is such that γ(0)=(0,0), and γ'(t)= (0,0) whenever γ(t)=(0,0) for some t∈R. Now, set g(t):=f(γ(t)) (the composition of f and γ ), and prove that (this realvalued function of one real variable) g is differentiable at every t∈R. Also prove that if γ∈C1(R,R2), then g∈C1(R,R). [Note that this shows that f has "some sort of derivative" (i.e., some rate of change) at the origin whenever it is restricted to a smooth curve that goes through the origin (0,0). (d) In spite of all this, prove that f is not (Fréchet) differentiable at the origin (0,0). (Hint: Show that the formula (Dvf)(0,0)=⟨(∇f)(0,0),v⟩ fails for some direction(s) v. Here ⟨⋅,⋅⟩ denotes the standard dot product in the plane R2). [Thus, f is not (Fréchet) differentiable at the origin (0,0). For, if f were differentiable at the origin, then the differential f′(0,0) would be completely determined by the partial derivatives of f; i.e., by the gradient vector (∇f)(0,0). Moreover, one would have that (Dvf)(0,0)=⟨(∇f)(0,0),v⟩ for every direction v; as discussed in class!]
(a) The partial derivatives D1f and D2f of the function f(x, y) are bounded in R2. Moreover, f is continuous.
(b) The directional derivative (Dvf)(0, 0) exists for a unit vector v, and its absolute value is at most 1. Additionally, f is Gâteaux differentiable at the origin (0, 0).
(c) The function g(t) = f(γ(t)) is differentiable at every t ∈ R, and if γ ∈ C1(R, R2), then g ∈ C1(R, R).
(d) Despite the aforementioned properties, f is not Fréchet differentiable at the origin (0, 0).
(a) To prove that the partial derivatives ∂f/∂x and ∂f/∂y are bounded in R², we need to show that there exists a constant M such that |∂f/∂x| ≤ M and |∂f/∂y| ≤ M for all (x, y) in R².
Calculating the partial derivatives:
∂f/∂x = [tex](0 - 2xy^2)/(x^4 + y^4)[/tex]= [tex]-2xy^2/(x^4 + y^4)[/tex]
∂f/∂y = [tex]2yx^2/(x^4 + y^4)[/tex]
Since[tex]x^4 + y^4[/tex] > 0 for all (x, y) ≠ (0, 0), we can bound the partial derivatives as follows:
|∂f/∂x| =[tex]2|xy^2|/(x^4 + y^4) ≤ 2|x|/(x^4 + y^4) \leq 2(|x| + |y|)/(x^4 + y^4)[/tex]
|∂f/∂y| = [tex]2|yx^2|/(x^4 + y^4) ≤ 2|y|/(x^4 + y^4) \leq 2(|x| + |y|)/(x^4 + y^4)[/tex]
Letting M = 2(|x| + |y|)/[tex](x^4 + y^4)[/tex], we can see that |∂f/∂x| ≤ M and |∂f/∂y| ≤ M for all (x, y) in R². Hence, the partial derivatives are bounded.
Furthermore, f is continuous since it can be expressed as a composition of elementary functions (polynomials, division) which are known to be continuous.
(b) To show the existence and bound of the directional derivative (Dvf)(0,0), we use the limit definition of the directional derivative. Let v = (v1, v2) be a unit vector.
(Dvf)(0,0) = lim(h→0) [f((0,0) + hv) - f(0,0)]/h
= lim(h→0) [f(hv) - f(0,0)]/h
Expanding f(hv) using the given formula: f(hv) = 0(hv²)/(h³) = v²/h
(Dvf)(0,0) = lim(h→0) [v²/h - 0]/h
= lim(h→0) v²/h²
= |v²| = 1
Therefore, the absolute value of the directional derivative (Dvf)(0,0) is at most 1.
(c) Let γ: R → R² be a differentiable curve such that γ(0) = (0,0), and γ'(t) ≠ (0,0) whenever γ(t) = (0,0) for some t ∈ R. We define g(t) = f(γ(t)).
To prove that g is differentiable at every t ∈ R, we can use the chain rule of differentiation. Since γ is differentiable, g(t) = f(γ(t)) is a composition of differentiable functions and is therefore differentiable at every t ∈ R.
If γ ∈ [tex]C^1(R, R^2)[/tex], which means γ is continuously differentiable, then g ∈ [tex]C^1(R, R)[/tex] as the composition of two continuous functions.
(d) To show that f is
not Fréchet differentiable at the origin (0,0), we need to demonstrate that the formula (Dvf)(0,0) = ⟨∇f(0,0), v⟩ fails for some direction(s) v, where ⟨⋅,⋅⟩ denotes the standard dot product in R².
The gradient of f is given by ∇f = (∂f/∂x, ∂f/∂y). Using the previously derived expressions for the partial derivatives, we have:
∇f(0,0) = (∂f/∂x, ∂f/∂y) = (0, 0)
However, if we take v = (1, 1), the formula (Dvf)(0,0) = ⟨∇f(0,0), v⟩ becomes:
(Dvf)(0,0) = ⟨(0, 0), (1, 1)⟩ = 0
But from part (b), we know that the absolute value of the directional derivative is at most 1. Since (Dvf)(0,0) ≠ 0, the formula fails for the direction v = (1, 1).
Therefore, f is not Fréchet differentiable at the origin (0,0).

y′′+y′−6y=30−3001(+−4),y(0)=0,y′(0)=0
The solution to the differential equation y′′+y′−6y=30−3001(+−4),y(0)=0,y′(0)=0 is y(t) = -250.08335e^(-3t) + 250.08335e^(2t) + 30t + 500.1667e^(-4t).
To solve the differential equation y′′ + y′ - 6y = 30 - 3001(t+e^(-4)), with initial conditions y(0) = 0 and y′(0) = 0, we can first find the general solution to the homogeneous equation y′′ + y′ - 6y = 0, which is given by:
r^2 + r - 6 = 0
Solving for r, we get:
r = -3 or r = 2
Therefore, the general solution to the homogeneous equation is:
y_h(t) = c1e^(-3t) + c2e^(2t)
y_p(t) = At + Be^(-4t)
y_p'(t) = A - 4Be^(-4t)
y_p''(t) = 16Be^(-4t)
16Be^(-4t) + (A - 4Be^(-4t)) - 6(At + Be^(-4t)) = 30 - 3001(t + e^(-4t))
(-6A+ 17B)e^(-4t) + A - 6Bt = 30 - 3001t
-6A + 17B = 0
A = 30
-6B = -3001
A = 30
B = 500.1667
y_p(t) = 30t + 500.1667e^(-4t)
y(t) = y_h(t) + y_p(t) = c1e^(-3t) + c2e^(2t) + 30t + 500.1667e^(-4t)
y(0) = c1 + c2 + 500.1667(1) = 0
y'(0) = -3c1 + 2c2 + 30 - 2000.6668 = 0
c1 = -250.08335
c2 = 250.08335
Therefore, the solution to the differential equation with initial conditions y(0) = 0 and y'(0) = 0 is:
y(t) = -250.08335e^(-3t) + 250.08335e^(2t) + 30t + 500.1667e^(-4t)

To join the points (2, 16) and (8, 4), we can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept.
First, let's calculate the slope (m) using the formula:
m = (y2 - y1) / (x2 - x1)
Substituting the coordinates of the two points:
m = (4 - 16) / (8 - 2)
m = -12 / 6
m = -2
Now that we have the slope, we can choose either of the two points and substitute its coordinates into the slope-intercept form to find the y-intercept (b).
Let's choose the point (2, 16):
16 = -2(2) + b
16 = -4 + b
b = 20
Now we have the slope (m = -2) and the y-intercept (b = 20), we can write the equation of the line:
y = -2x + 20
This equation represents the line passing through the points (2, 16) and (8, 4).

If we use the limit comparison test to determine, then the series Invalid element converges.A O limit comparison test is inconclusive, one must use another test .BO diverges .CO neither converges nor diverges.D O h
If we use the limit comparison test to determine the convergence or divergence of a series, we compare it to a known series with known convergence behavior. However, in the given question, it states "Invalid element," which does not provide any specific series for analysis. Therefore, we cannot draw a conclusion regarding the convergence or divergence of the series without further information.
The limit comparison test is a method used to determine the convergence or divergence of a series by comparing it to a series whose convergence behavior is already known. The test states that if the limit of the ratio of the terms of the two series exists and is a positive finite number, then both series either converge or diverge together. However, if the limit is zero or infinity, the test is inconclusive, and another test must be used to determine the convergence or divergence.
In this case, since we do not have a specific series to analyze, we cannot apply the limit comparison test. We cannot make any assertions about the convergence or divergence of the series based on the given information.
To determine the convergence or divergence of a series, various other tests can be employed, such as the ratio test, root test, integral test, or comparison tests (such as the direct comparison test or the limit comparison test with a suitable series). These tests involve analyzing the properties and behavior of the terms in the series to make a determination.

Consider the recurrence function
T(n) = 27T(n/3) + 274log n
Give an expression for the runtime T(n) if the recurrence can be solved with the
Master Theorem. Assume that T(n) = 1 for n ≤ 1.
The expression for the runtime of the given recurrence relation T(n) = 27T(n/3) + 274log n, solved using the Master Theorem, is Θ([tex]n^3[/tex]).
What is the asymptotic runtime complexity of the recurrence relation T(n) = 27T(n/3) + 274log n?The given recurrence relation is T(n) = 27T(n/3) + 274 log n. In order to determine the runtime complexity using the Master Theorem, we need to compare the given recurrence to the standard form of the theorem: T(n) = aT(n/b) + f(n).
In this case, we have:
a = 27
b = 3
f(n) = 274 log n
To apply the Master Theorem, we need to compare the growth rate of f(n) with [tex]n^{(log_b a)}[/tex]. In other words, we need to determine the relationship between f(n) and [tex]n^{(log_3 27)}.[/tex]
Since log_3 27 = 3, we have:
[tex]n^{(log_3 27)} = n^3[/tex]
Now let's compare f(n) with [tex]n^3[/tex]:
f(n) = 274 log n
[tex]n^3 = n^{(log_3 27)}[/tex]
Since log n is smaller than any positive power of n, we can conclude that f(n) is asymptotically smaller than [tex]n^3[/tex].
According to the Master Theorem, if f(n) is asymptotically smaller than [tex]n^c[/tex]for some constant c, then the runtime complexity of the recurrence relation is dominated by the term [tex]n^c[/tex].
In this case, since f(n) is smaller than [tex]n^3[/tex], the runtime complexity of the recurrence relation T(n) is Θ([tex]n^3[/tex]).
Therefore, the expression for the runtime T(n) is Θ([tex]n^3[/tex]).

The solution to the given system of differential equations is:
[tex]\(x(t) = \frac{4}{5} e^t - \frac{2}{3} e^{2t} + C_1\)\\\(y(t) = 5e^t - \frac{5}{3}e^{2t} + 3C_1t + C_2\)[/tex]
To solve the given system of differential equations by systematic elimination, we can eliminate one variable at a time to obtain a single differential equation. Let's begin by eliminating [tex]\(x(t)\)[/tex].
Differentiating the second equation with respect to [tex]\(t\)[/tex], we get:
[tex]\[\frac{d^2x}{dt^2} = e^t\][/tex]
Substituting this expression into the first equation, we have:
[tex]\(\frac{dy}{dt} - 2e^t \frac{dx}{dt} = 4x + x + e^t\)[/tex]
Simplifying the equation, we get:
[tex]\(\frac{dy}{dt} - 2e^t \frac{dx}{dt} = 5x + e^t\)[/tex]
Next, differentiating the above equation with respect to [tex]\(t\)[/tex], we have:
[tex]\(\frac{d^2y}{dt^2} - 2e^t \frac{d^2x}{dt^2} = 5 \frac{dx}{dt}\)[/tex]
Substituting [tex]\(\frac{d^2x}{dt^2} = e^t\)[/tex], we have:
[tex]\(\frac{d^2y}{dt^2} - 2e^{2t} = 5 \frac{dx}{dt}\)[/tex]
Now, let's eliminate [tex]\(\frac{dx}{dt}\)[/tex]. Differentiating the second equation with respect to [tex]\(t\),[/tex] we get:
[tex]\(\frac{d^2y}{dt^2} = 4e^t\)[/tex]
Substituting this expression into the previous equation, we have:
[tex]\(4e^t - 2e^{2t} = 5 \frac{dx}{dt}\)[/tex]
Simplifying the equation, we get:
[tex]\(\frac{dx}{dt} = \frac{4e^t - 2e^{2t}}{5}\)[/tex]
Integrating on both sides:
[tex]\(\int \frac{dx}{dt} dt = \int \frac{4e^t - 2e^{2t}}{5} dt\)[/tex]
Integrating each term separately, we have:
[tex]\(x = \frac{4}{5} e^t - \frac{2}{3} e^{2t} + C_1\)[/tex]
where [tex]\(C_1\)[/tex] is the constant of integration.
Now, we can substitute this result back into one of the original equations to solve for [tex]\(y(t)\)[/tex]. Let's use the second equation:
[tex]\(\frac{dy}{dt} = 4x + x + e^t\)[/tex]
Substituting the expression for [tex]\(x(t)\)[/tex], we have:
[tex]\(\frac{dy}{dt} = 4 \left(\frac{4}{5} e^t - \frac{2}{3} e^{2t} + C_1\right) + \left(\frac{4}{5} e^t - \frac{2}{3} e^{2t} + C_1\right) + e^t\)[/tex]
Simplifying the equation, we get:
[tex]\(\frac{dy}{dt} = \frac{16}{5} e^t - \frac{8}{3} e^{2t} + 2C_1 + \frac{4}{5} e^t - \frac{2}{3} e^{2t} + C_1 + e^t\)[/tex]
Combining like terms, we have:
[tex]\(\frac{dy}{dt} = \left(\frac{20}{5} + \frac{4}{5} + 1\right)e^t - \left(\frac{8}{3} + \frac{2}{3}\right)e^{2t} + 3C_1\)[/tex]
Simplifying further, we get:
[tex]\(\frac{dy}{dt} = 5e^t - \frac{10}{3}e^{2t} + 3C_1\)[/tex]
Integrating both sides with respect to \(t\), we have:
[tex]\(y = 5 \int e^t dt - \frac{10}{3} \int e^{2t} dt + 3C_1t + C_2\)[/tex]
Evaluating the integrals and simplifying, we get:
[tex]\(y = 5e^t - \frac{5}{3}e^{2t} + 3C_1t + C_2\)[/tex]
where [tex]\(C_2\)[/tex] is the constant of integration.
Therefore, the complete solution to the system of differential equations is:
[tex]\(x(t) = \frac{4}{5} e^t - \frac{2}{3} e^{2t} + C_1\)\\\(y(t) = 5e^t - \frac{5}{3}e^{2t} + 3C_1t + C_2\)[/tex]

Use the Laplace transform to solve the given initial value problem. y" - 12y85y = 0; y(0) = 6, y'(0) = 58 y(t) = [
The solution to the initial value problem is y(t) = [tex]2e^(-5t) + 4e^(-17t)[/tex].
To solve the given initial value problem using the Laplace transform, we'll follow these steps:
Take the Laplace transform of both sides of the differential equation using the linearity property and the derivatives property of the Laplace transform.
Solve for the Laplace transform of the unknown function, denoted as Y(s).
Apply the initial conditions to find the values of the Laplace transform at s=0.
Inverse Laplace transform Y(s) to obtain the solution y(t).
Let's solve the initial value problem:
Step 1:
Taking the Laplace transform of the differential equation, we have:
s²Y(s) - sy(0) - y'(0) - 12(sY(s) - y(0)) + 85Y(s) = 0
Step 2:
Simplifying the equation and isolating Y(s), we get:
(s² + 12s + 85)Y(s) = s(6) + 58 + 12(6)
Y(s) = (6s + 130) / (s² + 12s + 85)
Step 3:
Applying the initial conditions, we have:
Y(0) = (6(0) + 130) / (0² + 12(0) + 85) = 130 / 85
Step 4:
Inverse Laplace transforming Y(s), we can use partial fraction decomposition or the table of Laplace transforms to find the inverse Laplace transform. In this case, we'll use partial fraction decomposition:
Y(s) = (6s + 130) / (s² + 12s + 85)
= (6s + 130) / [(s + 5)(s + 17)]
Using partial fraction decomposition, we can write:
Y(s) = A / (s + 5) + B / (s + 17)
Multiplying both sides by (s + 5)(s + 17), we get:
6s + 130 = A(s + 17) + B(s + 5)
Expanding and equating coefficients, we have:
6 = 17A + 5B
130 = 5A + 17B
Solving these equations simultaneously, we find A = 2 and B = 4.
Therefore, Y(s) = 2 / (s + 5) + 4 / (s + 17)
Taking the inverse Laplace transform
y(t) = [tex]2e^(-5t) + 4e^(-17t)[/tex].
So the solution to the initial value problem is y(t) = [tex]2e^(-5t) + 4e^(-17t)[/tex].

If the surface area of the right rectangular prism is 310 square centimeters, what is the measure of the height h of the prism?
A 5 \mathrm{~cm}
B 5 \frac{1}{6} \mathrm{~cm}
C 10
D 13 \frac{3}{9} \mathrm{~cm}
The height h of the prism measures 5 cm (Option A) based on the given surface area.
To find the measure of the height of the prism, we need to understand the formula for the surface area of a right rectangular prism. The surface area of a prism is given by the formula: SA = 2lw + 2lh + 2wh, where l, w, and h represent the length, width, and height of the prism, respectively.
In this case, we are given that the surface area of the prism is 310 square centimeters. We can set up the equation as follows: 310 = 2lw + 2lh + 2wh.
Since we are asked to find the height, we can isolate the term 2lh and rearrange the equation as follows: 2lh = 310 - 2lw - 2wh.
Simplifying further, we get: lh = 155 - lw - wh.
Since we don't have specific values for the length and width, we cannot solve for the height directly. However, we can analyze the answer choices given.
Option A states that the height h is 5 cm. We can substitute this value into our equation: 5l = 155 - 5w - 5w.
Simplifying, we get: 5l = 155 - 10w.
We can see that this equation does not depend on the specific values of l and w, which means that regardless of their values, the equation holds true. Therefore, the measure of the height h of the prism is indeed 5 cm option A.

Explain how you can apply what you know about solving cosine equations to solving sin e equations. Use -1=6 sin 2 t as an example.
To solve the equation -1 = 6 sin(2t), we can apply our knowledge of solving cosine equations to solve it. The reason is that the sine function is closely related to the cosine function.
We can use a trigonometric identity to convert the sine equation into a cosine equation.
The trigonometric identity we can use is sin²θ + cos²θ = 1. By rearranging this identity, we get cos²θ = 1 - sin²θ. We can substitute this expression into our equation to obtain a cosine equation.
-1 = 6 sin(2t)
-1 = 6 * √(1 - cos²(2t)) [Using the identity cos²θ = 1 - sin²θ]
-1 = 6 * √(1 - cos²(2t))
Now we have a cosine equation that we can solve. Let's denote cos(2t) as x:
-1 = 6 * √(1 - x²)
Squaring both sides of the equation to eliminate the square root:
1 = 36(1 - x²)
36x² = 36 - 1
36x² = 35
x² = 35/36
Taking the square root of both sides:
x = ±√(35/36)
Now that we have the value of x, we can find the values of 2t by taking the inverse cosine:
cos(2t) = ±√(35/36)
2t = ±cos⁻¹(√(35/36))
t = ±(1/2)cos⁻¹(√(35/36))
So, we have solved the equation -1 = 6 sin(2t) by converting it into a cosine equation. This demonstrates how we can apply our knowledge of solving cosine equations to solve sine equations by using trigonometric identities and the relationship between the sine and cosine functions.

A firm issues three-month commercial paper with a $1000000
face value and pays an EAR of 7.4%. What is the amount the firm
receives?
If firm issues commercial paper with $1000000 face-value and pays EAR of 7.4%, then amount the firm will receive is $981500.
To calculate the amount the firm receives from issuing the three-month commercial paper, we need to determine the total interest earned over the three-month period.
The Effective Annual Rate (EAR) of 7.4% indicates the annualized interest rate. Since the commercial paper has 3-month term, we adjust the EAR to account for the shorter period.
To find the quarterly interest rate, we divide the EAR by the number of compounding periods in a year. In this case, since it is a 3-month period, there are 4-compounding periods in a year (quarterly compounding).
Quarterly interest rate = (EAR)/(number of compounding periods)
= 7.4%/4
= 1.85%,
Now, we calculate interest earned on "face-value" of $1,000,000 over 3-months,
Interest earned = (face value) × (quarterly interest rate)
= $1,000,000 × 1.85% = $18,500,
So, amount firm receives from issuing 3-month commercial paper is the face value minus the interest earned:
Amount received = (face value) - (interest earned)
= $1,000,000 - $18,500
= $981,500.
Therefore, the amount that firms receives is $981500.

The given initial value problem's solution is y(t) = e^(-2t)(2cos(4t) + (1/8)sin(4t))
To solve the given initial value problem, we can use the method of solving second-order homogeneous linear differential equations with constant coefficients.
The characteristic equation corresponding to the given differential equation is:
r^2 + 4r + 20 = 0
To solve this quadratic equation, we can use the quadratic formula:
r = (-b ± √(b^2 - 4ac)) / (2a)
In this case, a = 1, b = 4, and c = 20. Substituting these values into the quadratic formula, we get:
r = (-4 ± √(4^2 - 4(1)(20))) / (2(1))
r = (-4 ± √(-64)) / 2
r = (-4 ± 8i) / 2
r = -2 ± 4i
The roots of the characteristic equation are complex conjugates: -2 + 4i and -2 - 4i.
The general solution of the differential equation can be written as:
y(t) = e^(-2t)(c1cos(4t) + c2sin(4t))
To find the particular solution that satisfies the initial conditions, we substitute the initial values into the general solution and solve for the constants c1 and c2.
Given y(0) = 2:
2 = e^(-2(0))(c1cos(4(0)) + c2sin(4(0)))
2 = c1
Given y'(0) = -1:

a. To find the number of minutes needed for the cell phones to cost the same amount, we can set up an equation where the total cost from Cellular-Tastic (f) is equal to the total cost from Dirt-Cheap Cell (g). Let's denote the number of minutes as m.
For Cellular-Tastic (f):
Total cost = $20 (monthly fee) + $0.11 per minute * m
For Dirt-Cheap Cell (g):
Total cost = $55 (monthly fee) + $0.01 per minute * m
Setting these two expressions equal to each other, we have:
$20 + $0.11m = $55 + $0.01m
Simplifying the equation:
$0.1m = $35
m = $35 / $0.1
m = 350 minutes
Therefore, the two cell phone plans would cost the same amount when using 350 minutes.
b. To create a graph modeling this situation, we can plot the total cost on the y-axis and the number of minutes on the x-axis. The graph will have two lines, one representing Cellular-Tastic (f) and the other representing Dirt-Cheap Cell (g).
The y-intercept for Cellular-Tastic will be $20, and the slope will be $0.11 per minute. The y-intercept for Dirt-Cheap Cell will be $55, and the slope will be $0.01 per minute. The graph will intersect at the point where the two total costs are equal.
c. Using the graph, we can determine when each company would be a better option.
For a lower number of minutes, Cellular-Tastic (f) would be a better option as its monthly fee is lower compared to Dirt-Cheap Cell (g). The graph will show that the Cellular-Tastic line is initially lower than the Dirt-Cheap Cell line.
As the number of minutes increases, there will be a point where the two lines intersect. At this point (350 minutes), both plans will cost the same amount.
Beyond the intersection point, Dirt-Cheap Cell (g) becomes the better option for higher usage. As the number of minutes increases further, the Dirt-Cheap Cell line will be lower than the Cellular-Tastic line, indicating a lower total cost for Dirt-Cheap Cell.

3 Write the radius of each type of blood vessel in standard form.
The capillary is one of the minute blood vessels that
connect arterioles and venules. The radius of a capillary
is 5 × 10³ mm.
The venule is a small blood vessel that allows
deoxygenated blood to return from the capillaries
to the veins. The radius of a venule is 1 x 102 mm.
The arteriole is a small blood vessel that extends and
branches out from an artery and leads to capillaries.
The radius of an arteriole is 5.0 × 10¹ mm.

The radius of a capillary is 5 meters, the radius of a venule is 0.1 meters, and the radius of an arteriole is 0.05 meters.
To convert each measurement to meters and write them as powers of 10, we can use the following conversion factors:
1 centimeter (cm) = 0.01 meters (m)
1 millimeter (mm) = 0.001 meters (m)
1 micrometer (um) = 0.000001 meters (m)
1 nanometer (nm) = 0.000000001 meters (m)
1 picometer (pm) = 0.000000000001 meters (m)
Writing each measurement as a power of 10:
1 centimeter (cm) = 1 × 10^(-2) meters (m)
1 millimeter (mm) = 1 × 10^(-3) meters (m)
1 micrometer (um) = 1 × 10^(-6) meters (m)
1 nanometer (nm) = 1 × 10^(-9) meters (m)
1 picometer (pm) = 1 × 10^(-12) meters (m)
Now, let's write the radius of each type of blood vessel in standard form:
The radius of a capillary is given as 5 × 10^3 mm. To convert it to meters, we need to move three decimal places to the left since 1 mm is equal to 0.001 meters.
Radius of a capillary = 5 × 10^3 mm = 5 × 10^3 × 0.001 m = 5 × 10^0 m = 5 m
The radius of a venule is given as 1 × 10^2 mm. Using the same conversion factor, we can convert it to meters.
Radius of a venule = 1 × 10^2 mm = 1 × 10^2 × 0.001 m = 1 × 10^(-1) m = 0.1 m
The radius of an arteriole is given as 5.0 × 10^1 mm.
Radius of an arteriole = 5.0 × 10^1 mm = 5.0 × 10^1 × 0.001 m = 5.0 × 10^(-2) m = 0.05 m
Therefore, the radius of a capillary is 5 meters, the radius of a venule is 0.1 meters, and the radius of an arteriole is 0.05 meters.
