Answer:
B) ![(-2)^{3}](https://tex.z-dn.net/?f=%28-2%29%5E%7B3%7D)
Step-by-step explanation:
Given Quotient :
![\frac{(-2)^4}{-2}](https://tex.z-dn.net/?f=%5Cfrac%7B%28-2%29%5E4%7D%7B-2%7D)
We will use the property of exponents to simplify the quotient.
Applying quotient rule of exponents which can be given as:
![\frac{a^x}{a^y}=a^{x-y}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%5Ex%7D%7Ba%5Ey%7D%3Da%5E%7Bx-y%7D)
We have
![\frac{(-2)^4}{-2}](https://tex.z-dn.net/?f=%5Cfrac%7B%28-2%29%5E4%7D%7B-2%7D)
Any number without an exponent is known to have power of 1.
Thus the quotient can be written as:
⇒ ![\frac{(-2)^4}{(-2)^1}](https://tex.z-dn.net/?f=%5Cfrac%7B%28-2%29%5E4%7D%7B%28-2%29%5E1%7D)
Applying quotient rule.
⇒ ![(-2)^{4-1}](https://tex.z-dn.net/?f=%28-2%29%5E%7B4-1%7D)

Answer:
The angle of elevation is equal to 68.2 degrees
Step-by-step explanation:
As you can see from the image below we are trying to find the angle on the bottom right.
We know that the hypotenuse is equal to 14 and we know that the opposite is equal to 14. This means that we will be using Sine.
sin x = 13/14
divide:
sin x = 0.9285714286
now we need to use sin^-1
sin^-1 (0.9285714286) = 68.21321071
Round 68.21321071 to the nearest tenth:
68.2
The angle of elevation is 68.2 degrees!
