Answer:

The correct answer is 82

Step-by-step explanation:

1st piece=x

2nd piece=3x+3

3rd piece=4x-8

Combine like terms:

x+3x+4x=8x

3-8= -5

8x-5=175

8x-5+5=175+5

8x=180

x=22.5

1st piece=22.5 in

2nd piece=70.5 in

3rd piece= 82

3rd piece is the biggest, so the correct answer is 82

Answer:

  • a) 6.5 seconds
  • b) 13 seconds
  • c) 679 ft

Step-by-step explanation:

<u>Given function:</u>

  • h(t) = -16t^2 + 208t + 3

a) <u>Maximum height is the vertex.</u> The ball reaches the maximum after:

  • h = -208/2(-16) = 6.5 seconds

b) <u>Time the ball was in the air:</u>

  • -16t^2 + 208t + 3 = 0

Solving we get approximately t = 13 seconds

c) <u>Maximum height is at vertex, we found t above:</u>

  • h(6.5) = -16(6.5)^2 + 208*6.5 + 3 = 679 ft
