Answer:
25 ft
Step-by-step explanation:
The area of this landing pad is 1,962.5 ft², which equals πr².
We solve this equation for r²:
1962.5 ft²
r² = ----------------- = 625 ft²
3.14
Taking the square root of both sides, we get:
r = √(625 ft²) = 25 ft
The radius is 25 ft.
Answer:
![4\sqrt[3]{7x}](https://tex.z-dn.net/?f=4%5Csqrt%5B3%5D%7B7x%7D)
Step-by-step explanation:
Look for the same stuff under the radical symbol. Here, that "stuff" is "7x". Only one answer choice has 7x under the radical.
_____
Here, there are no cubic factors under the radical that can be factored out—either in the problem expression or in the answer choices. If there were cubic factors, you'd want to remove them before making the comparison.
For example, ∛(56x) would be a like radical to ∛(7x) because a cubic factor of 2^3 = 8 can be removed to make it be 2∛(7x).

Answer:

Step-by-step explanation:
Given function
is linear function. This linear function represents the straight line on the coordinate plane. The slope of this line is
Since the slope is negative, the linear function is decreasing for all x. This means

You ar geven the interval
So, the maximum value of the function is at the point x=-4 and the minimum value of the function is at the point x=3.
At x=-4,
