The directrix of the parabola 16(y + 3) = (x + 1)2 has the equation y = -7. find the coordinates of the
focus of the parabola.

show how you got the answer to

i'm pretty sure the answer is a. decreases with increase in

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

use photo math thats what i use u can scan the problem and it tells u the answer
