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
Answers
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.

Answers
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.

Step-by-step explanation:
Given
trigonometric function is
[tex]\dfrac{\cos 2x-\cos 4x}{\sin 2x+\sin 4x}[/tex]
Applying trigonometric formulae
[tex]\Rightarrow \cos C-\cos D=-\sin (\dfrac{C+D}{2})\sin (\dfrac{C-D}{2})\\\\\Rightarrow \sin C+\sin D=\sin (\dfrac{C+D}{2})\cos (\dfrac{C-D}{2})[/tex]
[tex]\Rightarrow \dfrac{\cos 2x-\cos 4x}{\sin 2x+\sin 4x}=\dfrac{2\sin 3x\cdot \sin x}{2\sin 3x\cdot \cos x}\\\\\Rightarrow \dfrac{\sin x}{\cos x}=\tan x[/tex]
option (b) is correct
[tex]\Rightarrow \dfrac{\cos 2x+\cos 4x}{\sin 2x-\sin 4x}=\dfrac{2\cos 3x\cdot \cos x}{2\cos 3x\cdot \sin (-x)}=-\cot x[/tex]

Answers
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.
