Part 4) -1/4 → 
Step-by-step explanation:
<u><em>The complete question in the attached figure</em></u>
we know that
To find out the non permissible replacements for y, equate the denominator of each expression equal to 0.
step 1
we have

Equate (2y-3) equal to 0.

solve for y
Adds 3 both sides.

Divide both sides by 2.

therefore
3/2 is the non permissible replacement for y.
step 2
we have

Equate (4y+1) equal to 0.

Subtract 1 both sides

Divide by 4 both sides

therefore
-1/4 is the non permissible replacement for y.
step 3
we have

Equate -5(y-1) equal to 0.

Divide by -5 both sides

Adds 1 both sides

therefore
1 is the non permissible replacement for y.
step 4
we have

Equate -2(y+7) equal to 0.

Divide by -2 both sides

Subtract 7 both sides

therefore
-7 is the non permissible replacement for y
Answer:
h = -0.0166t^2 + 30.
Step-by-step explanation:
The graph of the flight is a parabola which opens down and is symmetrical about the y axis, passes through the x axis at -42.5 and 42.5 and has a vertex at (0, 30).
So we have -a(t^2) + 30 = 0 where t is the time
(42.5)^2 * -a = -30 (42.5 as its 1/2 * 85).
a = 30/2806.25
= 0.01661
So the equation is height h = -0.0166t^2 + 30
