Answer:
The answer is -4x^2-7x-5
Step-by-step explanation:
Answer:
18 units
Step-by-step explanation:
(-4 , 10) and (-4, -8)
Distance = 
![= \sqrt{(-4-[-4])^{2}+(-8-10)^{2}}\\\\= \sqrt{(-4+4)^{2}+(-18)^{2}}\\\\=\sqrt{0 + 324}\\\\=\sqrt{324}\\\\= 18](https://tex.z-dn.net/?f=%3D%20%5Csqrt%7B%28-4-%5B-4%5D%29%5E%7B2%7D%2B%28-8-10%29%5E%7B2%7D%7D%5C%5C%5C%5C%3D%20%5Csqrt%7B%28-4%2B4%29%5E%7B2%7D%2B%28-18%29%5E%7B2%7D%7D%5C%5C%5C%5C%3D%5Csqrt%7B0%20%2B%20324%7D%5C%5C%5C%5C%3D%5Csqrt%7B324%7D%5C%5C%5C%5C%3D%2018)
Step-by-step explanation:
1. x^2 + 10x + 25
2. x^2 - 25

The volume of a cone uses the following formula:

Our diameter is 20 feet, so divide this by 2 to find the radius:

We now have all of our values need to fill in the formula. Plug in these values:




The volume of the cone is
1780 cubic feet.
