<h3>Answer:</h3>

2 seconds

<h3>Explanation:</h3>

Equation: g(x) = -16x² + 64x + 80

<u>In order to find the maximum</u>:

vertex : -b/2a

           = -64/2(-16)

           = -64/-32

           = 2

Maximum Height:

= -16(2)² + 64(2) + 80

= 144 ft

The vertex should be maximum as a is negative and parabola opening downwards

So

x coordinate of vertex

  • -/2a
  • -64/-32
  • 2

y coordinate is max height

  • -16(2)²+64(2)+80
  • -16(4)+128+80
  • -64+128+80
  • 128+16
  • 144ft

Vertex at (2,144)

The rocket would take 2s

Make y the subject of these equations.<br> by² = d<br> Jay = 6<br> ay - cy = d.<br> cy - b) = y
allsm [11]

Answer:

See all the answers  below.

Step-by-step explanation:

by² = d

Jay = 6

ay - cy = d.

cy - b) = y

Option A

by² = d

divide both side by b

y² = d/b

square both sides

y=√d/b

Option B

Jay = 6

Divide both sides by Ja

y= 6/Ja

Option C

ay - cy = d

y(a-c)=d

divide both sides by (a-c)

y= d/(a-c)

Option D

(cy - b) = y

y-cy=-b

y(1-c)=-b

y= -b/(1-c)
