For the function y=-1+6 cos(2pi/7(x-5)) what is the minimum value?

The value of y lie in the interval [-7,5] and the minimum value of given function is -7.

Step-by-step explanation:

The given function is

We know that the value of cosine function lies between -1 and 1.

By the above property of cosine function we get

Multiply 6 each side.

Subtract 1 from each side.

Therefore the value of y lie in the interval [-7,5] and the minimum value of given function is -7.

the answer is c.

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
