At a sports camp, there is one counselor for every 12 campers. If there are 156 campers attending the camp, which equivalent rat

Pepsi [2]

Hello There!

It is 1:12 for counselor to camper
If there are 156 campers, follow these steps:
1 + 12 = 13
156/12 = 13
1 x 13 = 13
12 x 12 = 156
The ratio now is 13:156.
Meaning there are 13 counselors.

Hope This Helps You!
Good Luck :)

What is the vertex of the graph of the function f(x)=x^2+8x-2 !?

Viktor [21]

Answer:

(-4, -18).

Step-by-step explanation:

f(x = x^2 + 8x - 2 Completing the square on x^2 + 8x:-

= (x + 4)^2 - 16 - 2

= (x + 4)^2 - 18

- which is the vertex form of f(x)

The vertex of

(x - h)^2 + k is at (h, k)

So the vertex of f(x) is at (-4, -18)
