Answer:
If the expression is 
, then the answer is the first option.
If the expression is 
, then the answer is the third option.
Step-by-step explanation:
Remember that when you have a radical expression in the form ![\sqrt[n]{x}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%7D)
, you can rewrite as:
Then:
- If the expression is , then you can rewrite it in the following radical form:
![=4\sqrt[7]{x^3}](https://tex.z-dn.net/?f=%3D4%5Csqrt%5B7%5D%7Bx%5E3%7D)
(This form matches with the first option.)
- If the expression is , then you can rewrite it in the following radical form:
![=\sqrt[7]{(4x)^3}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B7%5D%7B%284x%29%5E3%7D)
(This form matches with the third option).
Answer:
C. 76.81
Step-by-step explanation:
We must use one of the trigonometric ratios to find the length, L, of the ramp. If we use 16 as the reference angle, the 22 in would be our opposite side and the ramp length is the adjacent.
Therefore, we must use tan, which is 
:
The answer to your question is -19
