To solve the integral ∫(x^2)/(x^2 + 4) dx, we can use **trigonometric **substitution. Let x = 2tanθ, and then substitute the expressions for x and dx into the **integral**. After simplifying and integrating, we obtain the final result.

To solve the integral ∫(x^2)/(x^2 + 4) dx, we can use the trigonometric substitution x = 2tanθ. We choose this substitution because it helps us eliminate the term x^2 + 4 in the **denominator**.

Using this **substitution**, we find dx = 2sec^2θ dθ. Substituting x and dx into the integral, we get:

∫((2tanθ)^2)/(4 + (2tanθ)^2) * 2sec^2θ dθ.

Simplifying the expression, we have:

∫(4tan^2θ)/(4 + 4tan^2θ) * 2sec^2θ dθ.

Canceling out the common factors, we get:

∫(2tan^2θ)/(2 + 2tan^2θ) * sec^2θ dθ.

Simplifying further, we have:

∫tan^2θ/(1 + tan^2θ) dθ.

Using the identity 1 + tan^2θ = sec^2θ, we can rewrite the integral as:

∫tan^2θ/sec^2θ dθ.

Simplifying, we get:

∫sin^2θ/cos^2θ dθ.

Using the **trigonometric **identity sin^2θ = 1 - cos^2θ, we can rewrite the integral as:

∫(1 - cos^2θ)/cos^2θ dθ.

Expanding the integral, we have:

∫(1/cos^2θ) - 1 dθ.

Integrating term by term, we obtain:

∫sec^2θ dθ - ∫dθ.

Integrating sec^2θ gives us tanθ, and integrating dθ gives us θ. Therefore, the final result is:

tanθ - θ + C,

where C is the **constant **of integration.

So, the solution to the integral ∫(x^2)/(x^2 + 4) dx is tanθ - θ + C, where θ is determined by the substitution x = 2tanθ.

The required **coordinates** of the **centroid** are obtained in terms of the given limits.

Given a curve `y = 4 - 3x + x³` and a set of limits for x-axis, we need to find the centroid of the area bounded by the curve, x-axis, maximum and minimum ordinates. The formula to find the **centroid** of a curve is given by `(∫ydx/∫dx)`.Here, we can solve the integral `∫ydx` to find the area enclosed by the curve between given limits and `∫dx` to find the length of the curve between given limits.**Area** enclosed by curve between given limits`A = ∫(4 - 3x + x³)dx`

Integrating each term separately, we get:`A = [4x - 3/2 * x² + 1/4 * x⁴]_xmin^xmax`

Substituting the limits, we get:`A = [4xmax - 3/2 * xmax² + 1/4 * xmax⁴] - [4xmin - 3/2 * xmin² + 1/4 * xmin⁴]`Length of curve between given limits`L = ∫(1 + (dy/dx)²)dx`

Differentiating the curve with respect to x, we get:`dy/dx = -3 + 3x²`**Squaring** it and adding 1, we get:`1 + (dy/dx)² = 10 - 6x + 10x² + 9x⁴

`Integrating, we get:`L = ∫(10 - 6x + 10x² + 9x⁴)dx

`Integrating each term separately, we get:`L = [10x - 3x² + 2x³ + 9/5 * x⁵]_xmin^xmax`

Substituting the limits, we get:`L = [10xmax - 3xmax² + 2xmax³ + 9/5 * xmax⁵] - [10xmin - 3xmin² + 2xmin³ + 9/5 * xmin⁵]`Now, we can find the coordinates of the centroid by applying the formula `

(∫ydx/∫dx)`. Thus, the **coordinates** of the centroid are:`(x_bar, y_bar) = (∫ydx/∫dx)`

Substituting the respective values, we get:`(x_bar, y_bar) = [(3/4 * xmax² - 2 * xmax³ + 1/5 * xmax⁵) - (3/4 * xmin² - 2 * xmin³ + 1/5 * xmin⁵)] / [(10xmax - 3xmax² + 2xmax³ + 9/5 * xmax⁵) - (10xmin - 3xmin² + 2xmin³ + 9/5 * xmin⁵)]`

If a student is chosen at random from those who participated in the survey, what is the probability that the student is a female or does not participate in school sports? Answer Choices: 0. 39 0. 64 0. 78 1. 0

The **probability **that the student is a female or does not participate in school sports is 0.78.

Let's label the events: F = the student is female

S = the student participates in school **sports**. So, the probability of being female and the probability of not participating in sports are:

P(F) = 0.55P(S') = 0.6

Using the addition rule of probability, we can determine the probability of being female or not participating in sports:

P(F ∪ S') = P(F) + P(S') - P(F ∩ S')

We don't know P(F ∩ S'), but since the events are not mutually **exclusive**, we can use the formula:

P(F ∩ S') = P(F) + P(S') - P(F ∪ S')

We get:

P(F ∪ S') = P(F) + P(S') - P(F) - P(S') + P(F ∩ S')P(F ∪ S') = P(F ∩ S') + P(F') + P(S')P(F') = 1 - P(F) = 1 - 0.55 = 0.45P(F ∩ S') = P(F) + P(S') - P(F ∪ S')P(F ∩ S') = 0.55 + 0.6 - P(F ∪ S')

We **substitute**:

0.55 + 0.6 - P(F ∪ S') = 0.55 + 0.6 - 0.39P(F ∪ S') = 0.56

Now we use the above formula to get the answer:

P(F ∪ S') = P(F) + P(S') - P(F ∩ S')P(F ∪ S') = 0.55 + 0.6 - P(F ∩ S')P(F ∩ S') = 0.55 + 0.6 - 0.78

P(F ∩ S') = 0.37P(F ∪ S') = 0.55 + 0.6 - 0.37P(F ∪ S') = 0.78

Thus, the probability that the student is female or does not participate in school sports is 0.78. Therefore, the correct option is 0.78.

The volume of the largest right **circular cone **inscribed in a** sphere **of radius 13 is approximately 7893.79 cubic units.

To find the volume of the largest cone, we can consider that the cone's apex coincides with the center of the sphere. In such a case, the height of the cone would be equal to the **sphere's radius **(13 units).

The volume of a cone can be calculated using the formula V = (1/3)πr²h, where r is the radius of the cone's base and h is the height. In this scenario, the radius of the base of the cone would be the same as the radius of the sphere (13 units).

Substituting these values into the formula, we get V = (1/3)π(13²)(13) = 7893.79 cubic units (rounded to two decimal places).

Question * Let D be the region enclosed by the two paraboloids z = 3x²+ and z = 16-x²-Then the projection of D on the xy-plane is: 2 None of these This option This option This option This option 16

We are given the region D enclosed by two **paraboloids** and asked to determine the **projection** of D on the xy-plane. We need to determine which option correctly represents the projection of D on the xy-plane.

The two paraboloids are given by the equations [tex]z=3x^{2} +\frac{y}{2}[/tex] and [tex]z=16-x^{2} -\frac{y^{2} }{2}[/tex]

To determine the **projection** on the xy-plane, we set the **z-coordinate** to zero. This gives us the equations for the **intersection** curves in the xy-plane.

Setting z = 0 in both equations, we have:

[tex]3x^{2} +\frac{y}{2}[/tex] = 0 and [tex]16-x^{2} -\frac{y^{2} }{2}[/tex]= 0.

Simplifying these equations, we get:

[tex]3x^{2} +\frac{y}{2}[/tex] = 0 and [tex]x^{2} +\frac{y}{2}[/tex] = 16.

Multiplying both sides of the second equation by 2, we have:

[tex]2x^{2} +y^{2}[/tex] = 32.

Rearranging the terms, we get:

[tex]\frac{x^{2} }{16} +\frac{y^{2}}{4}[/tex]= 1.

Therefore, the correct representation for the projection of D on the xy-plane is [tex]\frac{x^{2} }{16} +\frac{y^{2}}{4}[/tex] = 1.

Find the general solution of the differential equation: y' + 3y = te - 24 Use lower case c for the constant in your answer.

The **general** solution of the given **differential equation** is y = (1/3)t² - 8 + c[tex]e^{(3t)}[/tex], where c is a constant.

To find the general solution of the given differential equation y' + 3y = te - 24, we can use the method of integrating **factors**. First, we rearrange the equation to isolate the y term: y' = -3y + te - 24.

The integrating factor is [tex]e^{(3t)}[/tex] since the **coefficient** of y is 3. Multiplying both sides of the equation by the integrating factor, we get [tex]e^{(3t)}[/tex]y' + 3[tex]e^{(3t)}[/tex]y = t[tex]e^{(3t)}[/tex] - 24[tex]e^{(3t)}[/tex].

Applying the product rule on the left side, we can rewrite the equation as d/dt([tex]e^{(3t)}[/tex]y) = t[tex]e^{(3t)}[/tex] - 24[tex]e^{(3t)}[/tex]. **Integrating** both sides with respect to t, we have [tex]e^{(3t)}[/tex]y = ∫(t[tex]e^{(3t)}[/tex] - 24[tex]e^{(3t)}[/tex]) dt.

Solving the integrals, we get [tex]e^{(3t)}[/tex]y = (1/3)t²[tex]e^{(3t)}[/tex] - 8[tex]e^{(3t)}[/tex] + c, where c is the constant of integration.

the data in the excel spread sheet represent the number of wolf pups per den from a random sample of 16 wolf dens. assuming that the number of pups per den is normally distributed, conduct a 0.01 significance level test to decide whether the average number of pups per den is at most 5.

The **computations** would need to be done manually or entered into statistical software using the sample mean, sample standard deviation, and sample size because the data is not properly given.

To conduct the **hypothesis test**, we need to follow these steps:

Step 1: State the null and alternative hypotheses:

Null hypothesis (H0): The average number of wolf pups per den is at most 5.

Alternative hypothesis (H1): The average number of wolf pups per den is greater than 5.

Step 2: Set the **significance level:**

The significance level (α) is given as 0.01, which indicates that we are willing to accept a 1% chance of making a Type I error (rejecting the null hypothesis when it is true).

Step 3: Conduct the test and calculate the **test statistic**:

Since we have a sample size of 16 and the population standard deviation is unknown, we can use a t-test. The formula for the test statistic is:

t = (X - μ) / (s / √n)

Where:

X is the sample mean

μ is the population mean under the null hypothesis (μ = 5)

s is the sample standard deviation

n is the sample size

Step 4: Determine the **critical value:**

Since the alternative hypothesis is that the average number of pups per den is greater than 5, we will perform a **one-tailed test**. At a significance level of 0.01 and with 15 degrees of freedom (16 - 1), the critical value can be obtained from a t-distribution table or using statistical software.

Step 5: Make a decision:

If the calculated test statistic is greater than the critical value, we reject the null hypothesis. Otherwise, we fail to reject the null hypothesis.

Without the actual data from the Excel spreadsheet, it is not possible to provide the exact calculations for the test statistic and critical value. You would need to input the data into statistical software or perform the calculations manually using the given sample mean, sample** standard deviation**, and sample size.

Then compare the calculated test statistic to the critical value to make a **decision** about rejecting or failing to reject the null hypothesis.

Using the first part of the fundamental theorem of calculus, we can find the derivative of the function g(s) = ∫[1 to s³] t² dt. The derivative g'(s) can be obtained by evaluating the integrand at the upper limit of integration s³ and multiplying it by the derivative of the upper limit, which is 3s².

According to the first part of the fundamental theorem of calculus, if we have a function defined as g(s) = ∫[a to b] f(t) dt, where f(t) is a continuous function, then the derivative of g(s) with respect to s is given by g'(s) = f(s) * (ds/ds).

In our case, we have g(s) = ∫[1 to s³] t² dt, where the upper limit of integration is s³. To find the derivative g'(s), we need to evaluate the integrand t² at the upper **limit** s³ and multiply it by the **derivative** of the upper limit, which is 3s².

Therefore, g'(s) = (s³)² * 3s² = 3s^8.

The given differential equation has two **singular points** at x = -2 and x = 2. Both singular points are regular because the **coefficient** of y'' does not vanish at these points. The singular point at x = -2 is irregular, while the singular point at x = 2 is regular.

To find the singular points of the given **differential equation**, we need to determine the values of x for which the coefficient of the highest derivative term, y'', becomes **zero**.

The given differential equation is:

(x^2 - 4)y'' + (x + 2)y' - (x - 2)^2y = 0

Let's find the **singular points** by setting the coefficient of y'' equal to zero:

x^2 - 4 = 0

**Factoring** the left side, we have:

(x + 2)(x - 2) = 0

Setting each factor equal to zero, we find two **singular points**:

x + 2 = 0 --> x = -2

x - 2 = 0 --> x = 2

So, the singular points of the differential equation are x = -2 and x = 2.

To classify these singular points as regular or irregular, we examine the **coefficient** of y'' at each point. If the coefficient does not vanish, the point is regular; otherwise, it is irregular.

At x = -2:

Substituting x = -2 into the given **equation**:

((-2)^2 - 4)y'' + (-2 + 2)y' - (-2 - 2)^2y = 0

(4 - 4)y'' + 0 - (-4)^2y = 0

0 + 0 + 16y = 0

The coefficient of y'' is 0 at x = -2, which means it vanishes. Hence, x = -2 is an **irregular** singular point.

At x = 2:

Substituting x = 2 into the given equation:

((2)^2 - 4)y'' + (2 + 2)y' - (2 - 2)^2y = 0

(4 - 4)y'' + 4y' - 0y = 0

0 + 4y' + 0 = 0

The coefficient of y'' is non-zero at x = 2, which means it does not vanish. Therefore, x = 2 is a **regular** singular point.

In conclusion, the given differential equation has two singular points: x = -2 and x = 2. The singular point at x = -2 is irregular, while the singular point at x = 2 is **regular**.

To find the maximum error in this approximation, we need to evaluate the fourth derivative of [tex]\sqrt{1+x}[/tex]and calculate the error bound using the **Lagrange form** of the remainder. The fourth derivative of [tex]\sqrt{1+x}[/tex] is given by d⁴/dx⁴ ([tex]\sqrt{1+x}[/tex]) = [tex]-3/8(1 + x)^{-9/2}[/tex]ξ.

Using the Lagrange form of the remainder, the maximum error is given by |R₃(2³)| = |(-3/8)(2³ + ξ)[tex]^{-9/2} (2^3 - 0)^4 / 4!|[/tex], where ξ is a value between 0 and 2³.

Evaluating the expression, we find |R₃(2³)| = |(-3/8)(2³ + ξ)^[tex]^{-9/2}[/tex] (8)|.

Since we don't have specific information about the value of ξ, we cannot determine the exact maximum error. However, we know that the magnitude of the error is bounded by |(-3/8)(2³ + ξ)[tex]^{-9/2}[/tex] (8)|, which depends on the **specific value** of ξ.

Solve the inequalities. Show your work as it is done in the examples. (Hint: One answer will be "no solution" and one answer will be "all real numbers".) |4x + 5| + 2 > 10

The solution to the inequality |4x + 5| + 2 > 10 is x < -3/2 or x > 1/2, which means the solution is "all **real numbers**" except between -3/2 and 1/2.

To solve the **inequality **|4x + 5| + 2 > 10, we need to eliminate the absolute value by considering both the positive and negative cases.

**Positive **case:

For 4x + 5 ≥ 0 (inside the absolute value), we have |4x + 5| = 4x + 5. Substituting this into the original inequality, we get 4x + 5 + 2 > 10. Solving this inequality, we find 4x > 3, which gives x > 3/4.

Negative case:

For 4x + 5 < 0 (inside the absolute **value**), we have |4x + 5| = -(4x + 5). Substituting this into the original inequality, we get -(4x + 5) + 2 > 10. Solving this inequality, we find -4x > 3, which gives x < -3/4.

Combining the solutions from both cases, we find that x > 3/4 or x < -3/4. However, we also need to consider the values where 4x + 5 = 0, which gives x = -5/4. Therefore, the final solution is x < -3/4 or x > 3/4, excluding x = -5/4.

In interval **notation**, this can be written as (-∞, -3/4) ∪ (-3/4, ∞), meaning "all real numbers" except between -3/4 and 3/4.

The exact** length of the curve **described by the** parametric equations** x = 2t^2 and y = 3t^3, where t ranges from 0 to 5, can be calculated.

Explanation:

To find the **length of the curve**, we can use the **arc length formula.** The arc length formula for a parametric curve is given by:

L = ∫[a,b] sqrt(dx/dt)^2 + (dy/dt)^2 dt

In this case, we have the parametric equations x = 2t^2 and y = 3t^3, where t ranges from 0 to 5.

To calculate the arc length, we need to find the derivatives dx/dt and dy/dt and then **substitute** them into the arc length formula. Taking the **derivatives,** we get:

dx/dt = 4t

dy/dt = 9t^2

Substituting these derivatives into the arc length formula, we have:

6) A cruise ship’s course is set at a heading of 142° at 18 knots (33.336 km/h). A 10 knot current flows at a bearing of 112°. What is the ground velocity of the cruise ship? (4 marks)

The ground velocity of the **cruise ship** is:

Groundvelocity = sqrt((Groundhorizontalvelocity)2 + Groundverticalvelocity)2)

To find the **ground velocity** of the cruise ship, we need to consider the vector addition of the ship's velocity and the current velocity.

Given:

Ship's heading = 142°

Ship's velocity = 18 knots

Current velocity = 10 knots

Bearing of the current = 112°

To calculate the horizontal and vertical components of the ship's velocity, we can use trigonometry.

Ship's **horizontal velocity component** = Ship's velocity * cos(heading)

Ship's horizontal velocity component = 18 knots * cos(142°)

Ship's **vertical velocity component** = Ship's velocity * sin(heading)

Ship's vertical velocity component = 18 knots * sin(142°)

Similarly, we can calculate the horizontal and vertical components of the current velocity:

Current's horizontal velocity component = Current velocity * cos(bearing)

Current's horizontal velocity component = 10 knots * cos(112°)

Current's vertical velocity component = Current velocity * sin(bearing)

Current's vertical velocity component = 10 knots * sin(112°)

To find the ground velocity, we add the horizontal and vertical components of the ship's velocity and the current velocity:

Ground horizontal velocity = Ship's horizontal velocity component + Current's horizontal velocity component

Ground vertical velocity = Ship's vertical velocity component + Current's vertical velocity component

Finally, we can calculate the magnitude of the ground velocity using the **Pythagorean theorem**:

Grountvelocity = sqrt((Groundhorizontalvelocity)2 + Groundverticalvelocity)2)

Evaluate the above expressions using the given values, and you will find the ground velocity of the cruise ship.

5. Let F(x,y) = r + y + ry +3. Find the absolute maximum and minimum values of F on D= {(,y) x2 + y2 51}.

We can compare these values to find the **absolute maximum **and **minimum values **of F(x, y).

To find the absolute maximum and **minimum values** of the function[tex]F(x, y) = r + y + ry + 3[/tex] on the domain[tex]D = {(x, y) | x^2 + y^2 ≤ 51}[/tex], we need to evaluate the function at critical points and boundary points of the domain. First, let's find the** critical points **by taking the partial derivatives of F(x, y) with respect to x and y:

[tex]∂F/∂x = r∂F/∂y = 1 + r[/tex]

To find critical points, we set both partial derivatives equal to zero:

[tex]r = 0 ...(1)1 + r = 0 ...(2)[/tex]

From equation (2), we can solve for r:

[tex]r = -1[/tex]

Now, let's evaluate the** function** at the critical point (r, y) = (-1, y):

[tex]F(-1, y) = -1 + y + (-1)y + 3F(-1, y) = 2y + 2[/tex]

Next, let's consider the boundary of the domain, which is the circle defined by [tex]x^2 + y^2 = 51.[/tex]To find the extreme values on the boundary, we can use the method of Lagrange multipliers.

Let's define the function [tex]g(x, y) = x^2 + y^2.[/tex] The constraint is [tex]g(x, y) = 51.[/tex]

Now, we set up the Lagrange equation:

[tex]∇F = λ∇g[/tex]

Taking the partial derivatives:

[tex]∂F/∂x = r∂F/∂y = 1 + r∂g/∂x = 2x∂g/∂y = 2y[/tex]

The Lagrange equation becomes:

[tex]r = λ(2x)1 + r = λ(2y)x^2 + y^2 = 51[/tex]

From the first equation, we can solve for λ in **terms** of r and x:

[tex]λ = r / (2x) ...(3)[/tex]

Substituting equation (3) into the second equation, we get:

[tex]1 + r = (r / (2x))(2y)1 + r = ry / xx + xr = ry ...(4)[/tex]

Next, we square both sides of equation (4) and substitute [tex]x^2 + y^2 = 51:(x + xr)^2 = r^2y^2x^2 + 2x^2r + x^2r^2 = r^2y^251 + 2(51)r + 51r^2 = r^2y^251(1 + 2r + r^2) = r^2y^251 + 102r + 51r^2 = r^2y^251(1 + 2r + r^2) = r^2(51 - y^2)1 + 2r + r^2 = r^2(1 - y^2 / 51)[/tex]

Simplifying further:

[tex]1 + 2r + r^2 = r^2 - (r^2y^2) / 51(r^2y^2) / 51 = 2rr^2y^2 = 102ry^2 = 102[/tex]

Taking the square root of both sides, we get:

[tex]y = ±√102[/tex]

Since the square root of 102 is approximately 10.0995, we have two values for [tex]y: y = √102 and y = -√102[/tex].

Substituting y = √102 into equation (4), we can solve for x:

[tex]x + xr = r(√102)x + x(-1) = -√102x(1 - r) = -√102x = -√102 / (1 - r)[/tex]

Similarly, substituting y = -√102 into equation (4), we can solve for x:

[tex]x + xr = r(-√102)x + x(-1) = -r√102x(1 - r) = r√102x = r√102 / (1 - r)[/tex]

Now, we have the following points on the boundary of the domain:

[tex](x, y) = (-√102 / (1 - r), √102)(x, y) = (r√102 / (1 - r), -√102)[/tex]

Let's evaluate the function F(x, y) at these points:

[tex]F(-√102 / (1 - r), √102) = -√102 / (1 - r) + √102 + (-√102 / (1 - r))√102 + 3F(r√102 / (1 - r), -√102) = r√102 / (1 - r) + (-√102) + (r√102 / (1 - r))(-√102) + 3[/tex]

To find the absolute maximum and minimum values of F(x, y), we need to compare the values obtained at the critical points and the points on the boundary.

Let's summarize the values obtained:

Find the equation of the tangent line to the curve when x has the given value. F(x) = x^2 + 5x ; x = 4 Select one: A. y =13x-16 B. y=-4x/25 +8/5 C. y=x/20+1/5 D.y=-39x-80

The correct answer for **tangent line** is A. y = 13x - 16.

A line that barely touches a curve (or function) at a specific location is said to be its **tangent line**. In calculus, the tangent line may cross the graph at any other point(s) and may touch the curve at any other point(s).

To find the **equation** of the tangent line to the curve defined by [tex]F(x) = x^2 + 5x[/tex] at x = 4, we can use the concept of differentiation.

First, let's find the **derivative** of F(x) with respect to x. Taking the derivative of [tex]x^2 + 5x[/tex], we get:

F'(x) = 2x + 5.

Now, to find the slope of the **tangent line** at x = 4, we substitute x = 4 into F'(x):

F'(4) = 2(4) + 5 = 8 + 5 = 13.

So, the slope of the tangent line is 13.

To find the y-intercept of the tangent line, we substitute x = 4 into the original function F(x):

[tex]F(4) = 4^2 + 5(4) = 16 + 20 = 36.[/tex]

Therefore, the point (4, 36) lies on the tangent line.

Using the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept, we can write the equation of the tangent line:

y = 13x + b.

To find b, we substitute the **coordinates** (x, y) = (4, 36) into the equation:

36 = 13(4) + b,

36 = 52 + b,

b = 36 - 52,

b = -16.

Therefore, the **equation** of the tangent line to the curve [tex]F(x) = x^2 + 5x[/tex] at x = 4 is:

y = 13x - 16.

Thus, the correct answer is A. y = 13x - 16.

To find the equation of the tangent line, we need to determine the **slope **of the tangent line and a point on the line.

First, let's find the **derivative **of y with respect to θ. Differentiating y = 2sin²(θ) using the chain rule, we get dy/dθ = 4sin(θ)cos(θ).

Next, we substitute θ = -π/3 into the derivative to find the slope of the tangent line at that **point**. dy/dθ = 4sin(-π/3)cos(-π/3) = -3√3/2.

Now, we need to find a point on the tangent line. Substitute θ = -π/3 into the **equation **x = 2cot(θ) to get x = 2cot(-π/3) = 2√3.

The students in Mr. Burton's class ordered 16 basic yearbooks and 8 deluxe yearbooks, for a total of $1,720. How much does each option cost?

The basic yearbook option costs $80, and the deluxe yearbook option **costs **$120.

To find the cost of each **yearbook **option, we can set up a system of equations based on the given information. Let's denote the cost of a basic yearbook as 'B' and the cost of a deluxe yearbook as 'D'.

From Mrs. Lane's class:

27B + 28D = 4135 (equation 1)

From Mr. Burton's class:

16B + 8D = 1720 (equation 2)

To solve this system of equations, we can use either substitution or elimination. Let's use the elimination method:

**Multiplying **equation 2 by 2, we have:

32B + 16D = 3440 (equation 3)

Now, **subtract **equation 3 from equation 1 to eliminate 'D':

(27B + 28D) - (32B + 16D) = 4135 - 3440

Simplifying, we get:

-5B + 12D = 695 (equation 4)

Now we have a new equation relating only 'B' and 'D'. We can solve this equation **together **with equation 2 to find the values of 'B' and 'D'.

Multiplying equation 4 by 8, we have:

-40B + 96D = 5560 (equation 5)

Adding **equation **2 and equation 5:

16B + 8D + (-40B + 96D) = 1720 + 5560

Simplifying, we get:

-24B + 104D = 7280

Dividing the equation by 8, we have:

-3B + 13D = 910 (equation 6)

Now we have a new equation **relating **only 'B' and 'D'. We can solve this equation together with equation 2 to find the values of 'B' and 'D'.

Now, we have the following system of equations:

-3B + 13D = 910 (equation 6)

16B + 8D = 1720 (equation 2)

Solving this system of **equations **will give us the values of 'B' and 'D', which represent the cost of each yearbook option.

Solving the system of equations, we find:

B = $80 (cost of a basic yearbook)

D = $120 (cost of a deluxe yearbook)

Therefore, the basic yearbook option costs $80, and the deluxe yearbook option costs $120.

for such more question on **cost**
