What is the phase shift of a periodic function?
a horizontal translation of the function
the horizontal length of one cycle of the function
the number of cycles of the function that occur in one horizontal unit
a vertical translation of the function

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

step-by-step explanation:

cats

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.
