Determine the range, amplitude, period, horizontal translation, and equation of the midline y = 0.25 cos 0.5(x – 1) – 3

the answer is 13 cm

cool? what is the actuall ?

step-by-step explanation:

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75

hope this !
