Answer:
You are correct!
Step-by-step explanation:
The formula is:
V=πr^2h
V = (3.14)(5^2)(8)
V of a cone = 1/3 * (3.14)(5^2)(8)
I think the answer is C.50 miles
Answer:
D. N = w² + 8w + 12
Step-by-step explanation:
The current size is w by w+4, so the area is ...
A = w(w+4)
When each dimension is increased by 2, the new size is (w+2) by (w+4+2). The latter dimension can be simplified to (w+6). Now, the new area is ...
N = (w+2)(w+6) = w² +8w +12 . . . . . . . matches choice D
Answer:
![y \ge \frac{4x-1}{5}](https://tex.z-dn.net/?f=y%20%5Cge%20%5Cfrac%7B4x-1%7D%7B5%7D)
Step-by-step explanation:
Given
![4x - 5y \le 1](https://tex.z-dn.net/?f=4x%20-%205y%20%5Cle%201)
Required
Solve for y
![4x - 5y \le 1](https://tex.z-dn.net/?f=4x%20-%205y%20%5Cle%201)
Subtract 4x from both sides
![- 5y \le 1-4x](https://tex.z-dn.net/?f=-%205y%20%5Cle%201-4x)
Divide both sides by -5 (the inequality sign changes)
![y \ge \frac{1- 4x}{-5}](https://tex.z-dn.net/?f=y%20%5Cge%20%5Cfrac%7B1-%204x%7D%7B-5%7D)
![y \ge \frac{4x-1}{5}](https://tex.z-dn.net/?f=y%20%5Cge%20%5Cfrac%7B4x-1%7D%7B5%7D)
Answer:
f(x)=-2x+1
Step-by-step explanation:
Once points are plotted, you can use the rise/run method to find the slope which is 2/1=2. Then you can determine that its a negative function since the y values decrease as x increases. Lastly, since the y-intercept is a 1, you can fill in the blanks for the basic y=mx+b equation.
