The area of the enlarged picture on the wall is gotten as; D: 486 in²

The formula for Linear scale factor is;

L.S = Image distance/object distance

Thus, from the attached image, we can find the Linear scale factor as;

L.S = OL'/OL

L.S = 54/ 12

L.S = 9/2

Area scale factor is equal to the square of linear scale factor. Thus;

Area scale factor = (9/2)²

Area scale factor = 81/4

Now,

81/4 = Area of larger rectangle/Area of smaller rectangle

Area of the smaller rectangle = 4 ×6 = 24 in²

Thus;

Area of enlarged picture on wall = (81/4) × 24

Area of enlarged picture on wall = 486 in²

The given triple integral is evaluated using cylindrical coordinates, where the limits of integration for r, theta, and z are found based on the bounds of the solid E. The final answer is 16.

To solve this triple integral, we first need to determine the limits of integration for each variable. Since the solid E is bounded by the planes z = x^2 and z = 12 - 3y, we can set up the following inequalities

0 ≤ z ≤ 12 - 3y

x^2 ≤ z

We also know that the base of the solid E is the rectangle R given by 0 ≤ x ≤ 2 and 0 ≤ y ≤ 4. Therefore, the limits of integration for x and y are

0 ≤ x ≤ 2

0 ≤ y ≤ 4

For z, we can use the inequalities above to set up the following limits:

x^2 ≤ z ≤ 12 - 3y

Now we can set up the triple integral

∫0^4 ∫0^2 ∫x^2^(12-3y) y dz dx dy

We can integrate with respect to z first

∫0^4 ∫0^2 ∫x^2^(12-3y) y dz dx dy

= ∫0^4 ∫0^2 [yz]x^2^(12-3y) dx dy

= ∫0^4 ∫0^2 y(12-3y-x^2) dx dy

Next, we integrate with respect to x

∫0^4 ∫0^2 y(12-3y-x^2) dx dy

= ∫0^4 [yx(12-3y-x^2)/2]0^2 dy

= ∫0^4 -2y^4 + 9y^3 - 6y^2 dy

= [-1/2 y^5 + 9/4 y^4 - 2y^3]0^4

= 64/4 = 16

Therefore, the value of the triple integral is 16.

a. There are 2 cycles in the graph.
b. The period of the graph is 360 degrees.
c. The amplitude of the graph is 2.


a. To determine the number of cycles in the graph, we need to count the number of complete repetitions of the pattern. In this case, there are 2 complete repetitions, so there are 2 cycles.

b. The period of a sine graph is the distance it takes to complete one full cycle. In this graph, one full cycle is completed in 360 degrees, so the period is 360 degrees.

c. The amplitude of a sine graph is the distance from the midline to the maximum or minimum point of the graph. In this case, the amplitude is 2 units. y = 2 sin θ.

The estimated regression model shows that as advertising increases by $1,000, the estimated mean sales increase by $80,000.

The estimated regression model is a mathematical equation that relates the dependent variable (sales) to the independent variable (advertising) based on a given set of data. In this case, the estimated regression model indicates that for every increase of $1,000 in advertising, the estimated mean sales increase by $80,000. This means that there is a positive correlation between advertising and sales, and the model predicts that increasing advertising expenditure will result in higher sales.

If each kite measures 6 inches across and 12 inches long. The square inches of the wall will be:  864 square inches.

Diagonals= d1 and d2

First step

Area =(1/2)×(d1×d2)

Area=(1/2)×(6×12)

Area =36 in²

Second step

1 feet = 12 inches

12 feet =  12×12

12 feet = 144 in

Third step

Number of square inches=(144/6)×36

Number of square inches=24×36

Number of square inches= 864 square inches

Step-by-step explanation:

Since we want to find the number of trips to the park for which paying daily admission is more expensive than purchasing a season pass​, we can express an inequality, like this:

total daily admission cost > season pass cost

The total daily admission cost, can be expressed as the number of days that this pass is purchased (n) times the daily admission cost ($39), and the season pass cost equlas $117, then we get:

$39*n > $117

From this expression we can solve for n, then we get:

Then, more than 3 daily passes would be more expensive than the season pass. Since it must be more than 3, the answer is 4 trips

The answer to the expression 2b x b is simply 2b^2. Exponentiation is a mathematical operation that raises a number to a power, and in this case, b is raised to the power of 2.

Alternatively, if exponentiation is not allowed, the answer to the expression is simply 2b * b, which can be simplified to 2b^2 as well.

So, the answer to the expression 2b x b is 2b^2, regardless of whether or not exponentiation is used.

The expression 2b x b represents the product of two scalars, 2 and b, multiplied by a scalar b.

The expression could represent a variety of quantities in mathematics and science, including the area of a rectangle, the volume of a cube, or the kinetic energy of an object, among others.

The line drawing tool is used to draw the equations Y=1+1.50X and Y= 18-1.25X and the intersection point is labeled.

To draw the lines and indicate the point of intersection, you can follow these steps:

1. Draw a coordinate system on a piece of paper or using a drawing software.

2. For line A, plot two points on the coordinate system using the equation Y = 1 + 1.50X. Choose any two X values and calculate the corresponding Y values using the equation.

3. Connect the two points with a straight line and label it as line A.

4. For line B, plot two points on the coordinate system using the equation Y = 18 - 1.25X. Choose any two X values and calculate the corresponding Y values using the equation.

5. Connect the two points with a straight line and label it as line B.

6. Find the point of intersection between line A and line B. This is the point where both equations are equal. You can calculate this point by solving the system of equations Y = 1 + 1.50X and Y = 18 - 1.25X simultaneously.

7. Once you find the X and Y values of the point of intersection, mark it on the coordinate system and label it as 'Equilibrium'.

To find the largest four-digit value of t such that the expression is an integer, we need to set up an equation and solve for t.

Let's denote the given expression as x:

x = √(t - √(t - √(t - √(t - ...)))

To simplify the expression, we notice that the inner square root can be represented by x itself. So we can rewrite the equation as:

x = √(t - x)

Squaring both sides to eliminate the square root:

x^2 = t - x

Rearranging the equation:

x^2 + x - t = 0

To find the largest four-digit value of t, we can iterate through the values of t starting from 9999 and solve the quadratic equation for x. We are looking for a positive integer solution for x. Once we find the largest value of t that satisfies this condition, we have our answer.

By solving the quadratic equation for different values of t, the largest four-digit value of t that satisfies the condition is 9985.
