Answer: f(x)=(x+3)^2-13 = (-3|-13)
Step-by-step explanation:
x^2+6x-4
x^2+6x+3^2-3^2-4
(x+3)^2-3^2-4
(x+3)^2-13
Answer:
the right answer is x+1
Step-by-step explanation:
1/2x+1
therefore :
2×1/2x+1
x+1

Determine the volume of the cone
The volume of a square pyramid is:

Where
a = base dimension
From the attachment, the base dimension of the square pyramid is 2r.
So:

The volume becomes;

To calculate the volume of the cone, we simply multiply the given ratio and the volume of the prism.
So, we have:

![V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}]](https://tex.z-dn.net/?f=V_2%20%3D%20%5Cfrac%7B%5Cpi%7D%7B4%7D%20%5B%20%5Cfrac%7B%282r%29%5E2h%7D%7B3%7D%5D)

Open bracket;

Cancel out 4

The above can be written as:


So, we have:
![V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}]](https://tex.z-dn.net/?f=V_2%20%3D%20%5Cfrac%7B%5Cpi%7D%7B4%7D%20%5B%20%5Cfrac%7B%282r%29%5E2h%7D%7B3%7D%5D)
