h(t)=-5t^2+10t+3 is the height of a diver above the water, t seconds after the diver leaves the springboard. How high above the
Kobotan [32]

Answer:

3 units

Step-by-step explanation:

So if we want to know how high the spring board is, this will need to be the time at which the diver is still at the top of the board, in this case t = 0 seconds.

So we will need to find h(0)

  • h(0) = 5(0)² + 10(0) + 3 = 0 + 0 + 3 = 3

lora16 [44]

Answer:

  • 425 min
  • $80

Step-by-step explanation:

<u>The equation to reflect the monthly plans:</u>

  • Plan A f(x) = 0.16x + 12
  • Plan B g(x) = 0.12x + 29

<u>We need to find the value of x when f(x) = g(x):</u>

  • 0.16x + 12 = 0.12x + 29
  • 0.16x - 0.12x = 29 - 12
  • 0.04x = 17
  • x = 17/0.04
  • x = 425 minutes

<u>The cost is:</u>

  • $0.16*425 + $12 = $80
