We can use trigonometry to solve this problem. Let x be the distance from the foot of the ladder to the building, and let y be the length of the ladder. Then, we have:
tan(52) = y/x (since tangent = opposite/adjacent, and y is opposite to the angle of elevation and x is adjacent)
We also know that the ladder reaches 12 feet above the ground, so we have:
y = 12 + x (since y is the hypotenuse of the right triangle formed by the ladder, the ground, and the building)
We can substitute the second equation into the first to get:
tan(52) = (12 + x)/x
Simplifying this equation, we get:
tan(52)x = 12 + x
Using a calculator to find the tangent of 52, we get:
1.2799x = 12 + x
Solving for x, we get:
0.2799x = 12
x = 42.87 feet (rounded to two decimal places)
Therefore, the foot of the ladder is approximately 42.87 feet away from the building.

Find the value of z such that 0.6318 of the area lies between −z and z. Round your answer to two decimal places.
A standard normal distribution table or a calculator again, we can find that the z-score that corresponds to this area is approximately 0.42.
Describe Standard Normal Distribution?The standard normal distribution is useful because it allows us to calculate probabilities for any normal distribution by converting the distribution to a standard normal distribution using a process called standardization. Standardization involves subtracting the mean of the distribution from each observation and then dividing by the standard deviation. The resulting values are called z-scores, and they represent the number of standard deviations that an observation is from the mean of the distribution.
Assuming a standard normal distribution, we know that 0.5 of the area lies between -z and z, since the normal distribution is symmetric around the mean. Therefore, we need to find the value of z such that the area between -z and z is 0.6318 - 0.5 = 0.1318.
Using a standard normal distribution table or a calculator, we can find that the area between the mean and z is 0.5 + 0.1318/2 = 0.5659. Therefore, the z-score that corresponds to this area is approximately 0.18.
Since the distribution is symmetric, the area between -z and z is twice the area between the mean and z, so we can solve for z:
0.1318/2 = 0.0659 of the area lies between the mean and z
Using a standard normal distribution table or a calculator again, we can find that the z-score that corresponds to this area is approximately 0.42.
Therefore, z = 0.42 rounded to two decimal places.

What is a polygon?A polygon is a two-dimensional geometric shape that is defined as a closed figure with straight sides. It is made up of line segments that connect at endpoints called vertices. The term polygon comes from the Greek words "poly" meaning many and "gonia" meaning angle, indicating that polygons have many angles.
Polygons can have different numbers of sides, with the most basic being a triangle, which has three sides and three angles. Other examples of polygons include squares, rectangles, pentagons, hexagons, and octagons. The sides of a polygon do not have to be equal in length or the angles between them do not have to be the same, but they must be straight lines and the polygon must be closed.

What are Heights and Distances in trigonometry?The ideas of angles, right triangles, and the trigonometric functions of sine, cosine, and tangent are used in trigonometry to calculate heights and distances.
It is possible to determine the height of an object or the distance between two objects by measuring the angle of elevation or depression between the observer's line of sight and the object being observed and the distance between them. These ideas are frequently applied in the engineering, navigation, and surveying industries.
14. In a right-angled triangle, if one angle is 45 degrees, then the other acute angle is also 45 degrees and hence,
Let AB = x
Using the trigonometric ratio for the 45 degree angle in the triangle:
tan(45) = opposite/adjacent
We know that the opposite side is BC = [tex]$24{\sqrt{2}}$[/tex] and the adjacent side is AB = x.
tan(45) = BC/AB

The surface area of the rectangular prism is 72 square meters.
Describe Rectangular Prism?A rectangular prism, also known as a rectangular parallelepiped, is a three-dimensional figure that consists of six rectangular faces. It is a polyhedron with two identical and parallel bases, which are rectangles, and four rectangular lateral faces. The height of the prism is the perpendicular distance between the two bases. The volume of a rectangular prism is given by the formula V = l × w × h, where l, w, and h are the length, width, and height of the prism, respectively. The surface area of a rectangular prism is given by the formula SA = 2lw + 2lh + 2wh, where l, w, and h have the same meanings as in the volume formula. Rectangular prisms are commonly encountered in everyday life, such as in the shape of boxes, rooms, and buildings.
The surface area of a rectangular prism can be found by adding up the area of all its faces.
Area of blue rectangles:
= 2 x (length x width)
= 2 x (2.4m x 2m)
= 9.6m²
Area of green rectangles:
= 2 x (length x width)
= 2 x (2.4m x 3m)
= 14.4m²
Area of yellow rectangles:
= 2 x (length x width)
= 2 x (2m x 3m)
= 12m²
Total surface area = sum of all face areas
= (2 x blue rectangles) + (2 x green rectangles) + (2 x yellow rectangles)
= 2(9.6m²) + 2(14.4m²) + 2(12m²)
= 19.2m² + 28.8m² + 24m²
= 72m²
Therefore, the surface area of the rectangular prism is 72 square meters.

Ruby wants to find the height of the tallest building in her city. She stands 190 feet away from the building. There is a tree 31 feet in front of her, which she knows is 20 feet tall. How tall is the building? (Round to the nearest foot.)
To solve this problem, we can use similar triangles. Let's call the height of the building "h". Then, we have two similar triangles: one formed by Ruby, the tree, and the top of the tree; and the other formed by Ruby, the building, and the top of the building.
We know that the height of the tree is 20 feet, and the distance from the tree to Ruby is 31 feet. We also know that the distance from Ruby to the building is 190 feet.
Using these values, we can set up a proportion:
h / (190 + 31) = 20 / 31
Simplifying the proportion, we get:
h / 221 = 20 / 31
Multiplying both sides by 221, we get:
h = (20 / 31) * 221
h ≈ 143.23
Therefore, the height of the building is approximately 143 feet. Rounded to the nearest foot, the height of the building is 143 feet.

Trey purchases 200 shares of Turner stock for per share. Trey pays in cash to complete the purchase. One year later, Trey sells the stock for per share. Part 2 Calculate the return that Trey earned on his investment of .
Answer: Formula
Step-by-step explanation:
Stocks x per share = return
Trey's return on investment, if the stock paid no dividends during the year, is 14.29%.
We have,
Purchase price per share: $50
Number of shares purchased: 200
Total purchase cost (excluding loan interest):
Purchase price per share * Number of shares purchased
= $50 * 200
= $10,000
Loan amount: $5,000
Loan interest rate: 10%
Interest paid on the loan:
Loan amount * Interest rate
= $5,000 * 10%
= $500
Total purchase cost (including loan interest):
Total purchase cost + Loan interest
= $10,000 + $500
= $10,500
Selling price per share: $60
Total revenue from selling the stock:
Selling price per share * Number of shares sold
= $60 * 200
= $12,000
Return on investment (ROI):
(Total revenue - Total purchase cost) / Total purchase cost
ROI = ($12,000 - $10,500) / $10,500
Simplifying the expression:
ROI = $1,500 / $10,500
ROI = 0.1429 (approximately)
To express the ROI as a percentage:
ROI as a percentage = 0.1429 * 100 = 14.29%

B= - 90. Negative number,
So, A=170
C=160. Correct answer
The values of A, B, and C are 30, 50, and 20, respectively.
What is the sum?
The sum is the result of adding two or more numbers together. The sum is found by performing the operation of addition, which involves combining the values of two or more quantities to find the total or the sum.
If A = 80 - B and C = 70 - B, and the sum of A, B, and C is 100, then we can write:
A + B + C = 100
Substituting A and C with their given values, we get:
(80 - B) + B + (70 - B) = 100
Simplifying and combining like terms, we get:
150 - B = 100
Subtracting 150 from both sides, we get:
-B = -50
Dividing both sides by -1, we get:
B = 50
Now that we know B = 50, we can substitute this value back into the equations for A and C:
A = 80 - B = 80 - 50 = 30
C = 70 - B = 70 - 50 = 20
Therefore, the values of A, B, and C are 30, 50, and 20, respectively.

A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. An equation of the form, y = ax² + bx + c where a≠0. We have a quadratic regression function is defined by f(x) = -0.1536x² + 3.3915x +88.738 --(1), where, f(x) = the number of birds in a park relative to the number of people x in the same park. We have to determine quadratic regression to estimate the number of people in the park when there are 80 birds. Now, f(x) = 80, substitute the known value in equation (1),
=> 80 = -0.1536x² + 3.3915x +88.738
=>0.1536x²- 3.3915x -88.738 + 80 = 0
=> 0.1536x²- 3.3915x - 8.738 = 0
=> x² - 22.08x - 56.88 = 0 --(2)
Using the quadratic formula for solution of (2), x = (-b ±√b² - 4ac)/2a, for ax² + bx + c = 0. So, [tex]x =\frac{ -(-22.08) ± \sqrt{(22.08)² + 4× 56.88}}{2}[/tex]
=> x = 24.41 or - 2.3331
but number of people can't be negative hence, the required value is 24.41 ~ 24.
