After 2 days without any deposits or withdrawals, the balance in Lin's sister's account would be -$14.57.

The bank will impose a $5.95 daily fee on Lin's sister if she doesn't make any deposits or withdrawals for each day that her account balance is less than zero.

Let's calculate the balance after two days starting with an account balance of -$2.67:

Account balance on Day 1: $2.67

Charged at: $5.95

New account balance: (-$2.67) - $5.95 = -$8.62

Second day: Account balance: -$8.62

Charged at: $5.95

New account balance: (-$8.62) - $5.95 = -$14.57

Therefore, after 2 days without any deposits or withdrawals, the balance in Lin's sister's account would be -$14.57.

The expression that describes the field of values (outputs) of the graph of f(x) = -2sin(x) is [-2, 2], and the amplitude of the graph is 2.

In the given function f(x) = -2sin(x), the coefficient of sin(x) is -2. The coefficient, also known as the amplitude, determines the vertical stretching or compressing of the graph. The absolute value of the amplitude represents the maximum displacement from the midline of the graph.

Since the amplitude is -2, we take its absolute value to obtain 2. This means that the graph of f(x) = -2sin(x) has a maximum displacement of 2 units above and below the midline.

Therefore, the field of values (outputs) of the graph is [-2, 2], representing the range of y-values that the graph of f(x) = -2sin(x) can attain.

A key idea in calculus is an indefinite integral, commonly referred to as an antiderivative. It symbolises a group of functions that, when distinguished, produce a certain function. The integral symbol () is used to represent the indefinite integral of a function, and it is usually followed by the constant of integration (C). By using integration techniques and principles, it is possible to find an endless integral by turning the differentiation process on its head.

At point (-1/2, 3/2), the equation of the tangent line to the parabola y = 2x² is: y - 3/2 = 2(-1/2)(x + 1/2) => y = -x + 2, while the equation of the tangent line at point (1, 1) is y - 1 = -1(x - 1) => y = -x + 2.

Hence, the two lines are the same. The equation of the line passing through the point (0, 1) and (-1/2, 3/2) is: y - 1 = (3/2 - 1) / (-1/2 - 0)(x - 0) => y = -2x + 1.

The area of the region enclosed by the two curves can be found by evaluating the following integral: [tex]∫[a,b] [f(x) - g(x)] dx[/tex], where a = -1/2 and b = 1, and f(x) and g(x) are the equations of the two curves respectively.f(x) = 2x² and g(x) = x + 1.

Hence, the integral is[tex]∫[-1/2,1] [2x² - (x + 1)] dx = ∫[-1/2,1] [2x² - x - 1] dx = [(2/3)x³ - (1/2)x² - x] ∣[-1/2,1]= [(2/3)(1)³ - (1/2)(1)² - (1)] - [(2/3)(-1/2)³ - (1/2)(-1/2)² - (-1/2)][/tex]= 5/6.

The area of the region enclosed by the two curves is 5/6.

Therefore, the integral that would determine the area of the region shown enclosed by y = 2x², y - x = 1 and x-axis is: [tex]$$\int_{-\frac{1}{2}}^{1} \left(2x^2-x-1\right) dx$$[/tex] for the solutions.

The given initial value problem is y' = (1 – 7x)y, y(0) = 6.Find the solution of the given initial value problem in explicit form:By separation of variables, we can write:y' / y = (1 – 7x)dx. Integrating both sides with respect to x, we have ln |y| = x – (7/2)x^2 + C, where C is a constant of integration. Exponentiating both sides, we get:|y| = e^(x – (7/2)x^2 + C).

Let's consider the constant of integration as C1= e^C and write the equation as follows:|y| = e^x * e^(-7/2)x^2 * C1, where C1 is a positive constant as it is equal to e^C.

Taking the logarithm on both sides, we have ln y = x – (7/2)x^2 + ln C1, for y > 0andln(-y) = x – (7/2)x^2 + ln C1, for y < 0.

Now, we need to use the given initial value y(0) = 6 to find the value of C1 as follows:6 = e^0 * e^0 * C1 => C1 = 6.

Therefore, the solution of the given initial value problem in explicit form is y = e^x * e^(-7/2)x^2 * 6  (for y > 0)and y = - e^x * e^(-7/2)x^2 * 6  (for y < 0).

Naron is three times older than his sister, which means his age is 3X.

Let's assume that the age of Naron's sister is X years old. According to the question, Naron is three times older than his sister, which means his age is 3X.
In two years, Naron's age will be 3X + 2, and his sister's age will be X + 2. The question states that in two years, Naron will be twice as old as his sister.
So, we can write the equation:
3X + 2 = 2(X + 2)
Solving for X, we get:
X = 2
This means that Naron's sister is currently 2 years old. Therefore, Naron's age is 3 times older than his sister, which is 6 years old.
In summary, Naron is currently 6 years old, and his sister is currently 2 years old. Let N represent Naron's age and S represent his sister's age. According to the given information, N = 3S, which means Naron is 3 times older than his sister. In 2 years, Naron's age will be N+2, and his sister's age will be S+2. At that time, Naron will be twice as old as his sister, so N+2 = 2(S+2).
Now, we have two equations:
1) N = 3S
2) N+2 = 2(S+2)
Substitute equation 1 into equation 2:
3S+2 = 2(S+2)
Solve for S:
3S+2 = 2S+4
S = 2
Now, substitute the value of S back into equation 1:
N = 3(2)

the correct option is option d): ∫(x² cos(3x)) dx = (x/3 + 1/27) * sin(3x) + C. To solve the integral ∫(x² cos(3x)) dx, we can use integration by parts.

Let's use the following formula for integration by parts:

∫(u * v) dx = u * ∫v dx - ∫(u' * ∫v dx) dx,

where u' is the derivative of u with respect to x.

In this case, let's choose:

u = x² => u' = 2x,

v = sin(3x) => ∫v dx = -cos(3x)/3.

Now, applying the formula:

∫(x² cos(3x)) dx = x² * (-cos(3x)/3) - ∫(2x * (-cos(3x)/3)) dx.

Simplifying:

∫(x² cos(3x)) dx = -x² * cos(3x)/3 + 2/3 * ∫(x * cos(3x)) dx.

Now, we have a new integral to solve: ∫(x * cos(3x)) dx.

Applying integration by parts again:

Let's choose:

u = x => u' = 1,

v = (1/3)sin(3x) => ∫v dx = (-1/9)cos(3x).

∫(x * cos(3x)) dx = x * ((1/3)sin(3x)) - ∫(1 * ((-1/9)cos(3x))) dx.

Simplifying:

∫(x * cos(3x)) dx = (x/3) * sin(3x) + (1/9) * ∫cos(3x) dx.

The integral of cos(3x) can be easily found:

∫cos(3x) dx = (1/3)sin(3x).

Now, substituting this back into the previous expression:

∫(x * cos(3x)) dx = (x/3) * sin(3x) + (1/9) * ((1/3)sin(3x)) + C.

Simplifying further:

∫(x * cos(3x)) dx = (x/3) * sin(3x) + (1/27) * sin(3x) + C.

Combining the terms:

∫(x * cos(3x)) dx = (x/3 + 1/27) * sin(3x) + C.

Therefore, the correct option is option d):

∫(x² cos(3x)) dx = (x/3 + 1/27) * sin(3x) + C.

The condition of the Alternating Series Test that is not satisfied is A. The terms of the series are not nonincreasing in magnitude.

To show that the given series diverges and determine which condition of the Alternating Series Test is not satisfied, let's analyze the series and its terms.

The series is represented by Σ((-1)^(k+1) / (2k + 1)), where k ranges from 1 to 9. The terms of the series can be denoted as ak = |((-1)^(k+1) / (2k + 1))|.

To identify the behavior of ak, we observe that as k increases, the denominator (2k + 1) becomes larger, while the numerator (-1)^(k+1) alternates between -1 and 1. Therefore, ak is a decreasing function for all k. This eliminates options A and C.

To determine which condition of the Alternating Series Test is not satisfied, we evaluate the limit as k approaches infinity: lim(k→∞) ak. As k increases without bound, the magnitude of the terms ak approaches 0 (since ak is decreasing), satisfying the condition lim(k→∞) ak = 0.

Hence, the condition that is not satisfied is A. . Since ak is a decreasing function, the terms are indeed nonincreasing. Therefore, the main answer is that the condition not satisfied is A.

The line integral R is evaluated by splitting it into two components: Scy'd.r and rdy. The first component is calculated using the parametric equations of the parabola, while the second component simplifies to the integral of ydy over the given range.

To evaluate the line integral R, we need to calculate the two components separately and then sum them. Let's start with the first component, Scy'd.r. Since the line integral is defined along the arc of the parabola r = 4 - y², we can express the parabola parametrically as x = y and z = 4 - y². We then calculate the differential of position vector dr = dx i + dy j + dz k, which simplifies to dy j + (-2y dy) k. Taking the dot product of Scy'd.r, we have S c(y dy) . (dy j + (-2y dy) k). Integrating this expression over the given range (-5, -3) to (0, 2), we obtain the first component of the line integral.

Moving on to the second component, rdy, we simply integrate ydy over the same range (-5, -3) to (0, 2). This integral evaluates to the sum of the antiderivative of y²/2 evaluated at the upper and lower limits.

At a unit price of $30, the consumer surplus is approximately $300.

To calculate the consumer surplus at the indicated unit price, we need to integrate the demand function up to that price and subtract it from the total area under the demand curve.

Given the demand equation: p = 70 - 9Q, where p represents the unit price and Q represents the quantity demanded, we can solve the equation for Q:

p = 70 - 9Q

9Q = 70 - p

Q = (70 - p)/9

To find the consumer surplus at a unit price of p, we integrate the demand function from Q = 0 to Q = (70 - p)/9:

Consumer Surplus = ∫[0, (70 - p)/9] (70 - 9Q) dQ

Integrating the demand function, we have:

Consumer Surplus = [70Q - (9/2)Q^2] |[0, (70 - p)/9]

               = [70(70 - p)/9 - (9/2)((70 - p)/9)^2] - [0]

               = (70(70 - p)/9 - (9/2)((70 - p)/9)^2)

To calculate the consumer surplus at a specific unit price, let's consider the example where p = 30:

Consumer Surplus = (70(70 - 30)/9 - (9/2)((70 - 30)/9)^2)

               = (70(40)/9 - (9/2)(10/9)^2)

               = (2800/9 - (9/2)(100/81))

               = (2800/9 - 100/9)

               = 2700/9

               ≈ 300

The statement "The Test for Divergence applies to the series Σ 52 n=1" is true. The series 2-1(-1)n-1 is conditionally convergent but not absolutely convergent.

The Test for Divergence is a criterion used to determine if an infinite series converges or diverges. According to the test, if the limit of the n-th term of a series does not equal zero, then the series diverges. In this case, the series Σ 52 n=1 does not have a specific term defined, so the limit of the n-th term cannot be calculated. Hence, the Test for Divergence applies.

The series 2-1(-1)n-1 is an alternating series, where the terms alternate in sign. For an alternating series, the absolute value of the terms should approach zero in order for the series to be absolutely convergent. In this case, as n approaches infinity, the denominator, represented by Vn+1, will grow without bound, making the absolute value of the terms approach infinity. Therefore, the series 2-1(-1)n-1 is not absolutely convergent. However, it can be conditionally convergent, meaning that it converges when both the positive and negative terms are combined.

The area between the birth rate and death rate curves over the interval [0, 10] is 5478.38 (rounded to two decimal places).

To find the area between the curves of the birth rate function and the death rate function over a given interval, we need to calculate the definite integral of the difference between the two functions. In this case, we'll integrate the expression b(t) - d(t) over the interval [0, 10].

The birth rate function is given as b(t) = 2500e^(0.023t) people per year,

and the death rate function is given as d(t) = 1430e^(0.019t) people per year.

To find the area between the curves, we can evaluate the definite integral:

Area = ∫[0, 10] (b(t) - d(t)) dt

= ∫[0, 10] (2500e^(0.023t) - 1430e^(0.019t)) dt

To compute this integral, we can use numerical methods or software. Let's use a numerical approximation with a calculator or software:

Area ≈ 5478.38

Therefore, the approximate area between the birth rate and death rate curves over the interval [0, 10] is 5478.38 (rounded to two decimal places).

The minimum value of f (x,y,z) = 2x2 + y2 + 3z2 subject to the constraint 2x – 3y - 4z = 49 is 7075/169 using the method of Lagrange multipliers.

To solve this problem, we introduce a Lagrange multiplier λ and form the function

F(x,y,z,λ) = 2x^2 + y^2 + 3z^2 + λ(2x – 3y – 4z – 49)

Taking partial derivatives with respect to x, y, z, and λ, we get

∂F/∂x = 4x + 2λ

∂F/∂y = 2y – 3λ

∂F/∂z = 6z – 4λ

∂F/∂λ = 2x – 3y – 4z – 49

Setting these to zero, we have a system of four equations:

4x + 2λ = 0

2y – 3λ = 0

6z – 4λ = 0

2x – 3y – 4z = 49

Solving for x, y, z, and λ in terms of each other, we get

x = -λ/2

y = 3λ/2

z = 2λ/3

λ = -98/13

Substituting λ back into the expressions for x, y, and z, we get

x = 49/13

y = -147/26

z = -98/39

Finally, substituting these values into the expression for f(x,y,z), we find that the minimum value is f(49/13, -147/26, -98/39) = 7075/169

Hal did not make any errors in the procedure. His approach follows a logical and accurate method to approximate the square root of 82.5. Option D.

Hal did not make an error in the procedure. Let's analyze each step to confirm this:

Step 1: Hal correctly determines that the square root of 82.5, denoted as √82.5, lies between 9 and 10. This is because the value of 82.5 falls between the squares of 9 (81) and 10 (100). So, there is no error in step 1.

Step 2: Hal squares the tenths closer to 9, which are 9.0, 9.1, and 9.2. This is a correct step, and Hal correctly calculates the squares as 81.00, 82.81, and 84.64, respectively. Therefore, there is no error in step 2.

Step 3: Hal squares the hundredths closer to 9.1, which are 9.08 and 9.09. He correctly calculates the squares as 82.44 and 82.62, respectively. Since 82.5 lies between these two values, Hal chooses 9.09 as the best approximation. There is no error in step 3.

Step 4: Hal determines that 82.5 is closer to 82.62 than it is to 82.44, leading him to select 9.09 as the best approximation for √82.5. This is a correct decision based on the values obtained in previous steps. Hence, there is no error in step 4. Option D is correct.

Answer:

ITS D

Step-by-step explanation:

The total distance travelled by the particle from t=1 to t=4 is 98 feet.

1) We can find velocity by taking the derivative of position i.e. s'(t)=15. It means that the particle is moving with a constant velocity of 15 ft/s when acceleration is zero.2) The particle is moving in the positive direction if its velocity is positive i.e. s'(t)>0. Similarly, the particle is moving in the negative direction if its velocity is negative i.e. s'(t)<0.Using s'(t)=15, we can see that the particle is always moving in the positive direction.3) We have to find all the local (relative) extrema of the position function. Using s(t)=15t-2, we can calculate the first derivative as s'(t)=15. The derivative of s'(t) is zero which shows that there are no local extrema on the given interval.4) The given function is s(t)=15t-2. We need to find the integral of s(u) from t=1 to t=4. Using the integration formula, we can calculate the integral as:S(t)=∫s(u)du=t(15t-2)dt= 15/2 t^2 - 2t + C Putting the limits of integration and simplifying.
