When the two segments intersect they form a 90-degree angle implying that the lines are perpendicular.
Find the value of each variable that makes the equation true.
a. 2^5 x 2^3 = 2^a
b. 7^4/7^b = 7^-2
c. 8^c = 1/64
a. 2⁵ × 2^(3) = 2^(a) is a = 8.
b. 7⁴/[tex]7^b[/tex] = 7⁻² is b = 6.
c. [tex]8^c[/tex] = 1/64 is c = - 2.
What are some rules of exponents?Some common rules of exponents are
[tex]{a^b}\times{a^c} = a^{b + c}[/tex].
[tex]\frac{a^b}{a^c} = a^{b - c}[/tex]
We can only add and subtract exponents only when we have the same base.
Given,
2⁵ × 2³ = [tex]2^a[/tex].
[tex]2^{5+3}[/tex]= 2^(a).
[tex]2^8[/tex] = [tex]2^a[/tex]
a = 8.
[tex]\frac{7^4}{7^b}[/tex] = [tex]7^{-2}[/tex]
[tex]7^{4-b}[/tex] = [tex]7^{-2}[/tex].
4 - b = - 2.
- b = - 6.
b = 6.
[tex]8^c[/tex] = 1/64.
[tex]8^c[/tex] = 1/[tex]8^2[/tex].
[tex]8^c[/tex] = [tex]8^{-2}[/tex]
c = - 2.

Answer:
They are not similar.
Step-by-step explanation:
The angles of a triangle add up to be 180°. If they were similar, the triangle angles would have to be 60°, 40°, and 80°. Because one of the angles is 81°, the triangles cannot be similar.
81° + 40° + 60° does not equal 180.

A rectangle is 1 2/5 in. by 2 1/2 in. What is the rectangle’s perimeter?
Answer:
b. 7 4/5 in
Step-by-step explanation:
First, turn 1 2/5 and 2 1/2 into decimals which would be 1.4 and 2.5. Then, multiply 1.4 by 2 and 2.5 by 2 since you have to add up all the sides of the rectangle. Then, add the products to get the perimeter of 7.8 inches. (4/5 = 0.8).

Identify the area of a regular hexagon with side length 17 in. rounded to the nearest tenth.
Answer:
750.8in squared
Step-by-step explanation:
The area of a regular polygon is one-half times the length of the apothem times the perimeter.
Notice that the formula combines the areas for the six triangles that fit inside the hexagon.
The perimeter is equal to the sum of the six triangle bases and the apothem is the height of each triangle.
The interior angles of the hexagon have a measure of 120°
, so the angles at the base of the triangle (and the third angle) have measure 60°
.The height forms a 30°−60°−90°
triangle, which has one leg equal to half of the hexagon side, or 8.5 in.
, and the other leg equal to 8.53–√ in
The figure shows a regular hexagon. Each angle of the hexagon measures 120 degrees. There is a triangle inside the hexagon. The base of the triangle coincides with one of the sides of the hexagon and one of the vertices of the triangle is the center of the hexagon. The length of the apothem is 8.5 times square root of 3 inches. The angles at the base of the triangle measure 60 degrees. The angle between the apothem and the side of the triangle measures 30 degrees. The apothem divides the base of the triangle into two parts. One of the parts is 8.5 inches long.
Find the perimeter of the hexagon.
P=6(17)
Simplify.
P=102in.
The formula for the area is A=12aP
. Substitute the known values and simplify.
A=12(8.53–√)(102)
=433.53–√in2
Round to the nearest tenth as 750.8 in
Therefore, the area of the regular hexagon with side length 17in.
is A≈7508. in2

Several million lottery tickets are sold, and 21% of the tickets are held by men. Suppose you select a random sample of people and let X represent the number of people in your sample for which are men with winning tickets. What type of random variable is X?
hypergeometric
Bernoulli
poisson
uniform
Answer:
hypergeometric
Step-by-step explanation:
For each winning ticket, there are only two possible outcomes. Either it is held by a men, or it is not.
There is a set number of X, and as the number of winning tickets decrease, the probability of a winning ticket being held by a men can decrease or increase. This is a characteristic of the hypergeometric distribution.
