Answer:

  • 6.25 seconds

Step-by-step explanation:

<u>Using the the equation </u>

  • h = 100t − 16t^2

<u>The ball hits the ground, when h = 0, solving below equation:</u>

  • 100t − 16t^2 = 0
  • 4t(25 - 4t) = 0
  • t = 0 seconds, this is the starting point when ball was hit
  • 25 - 4t = 0 ⇒ 4t = 25 ⇒ t= 25/4 = 6.25 seconds later the ball hits the ground

Problem in image. Explain it too.
alexandr1967 [171]

\sqrt{40}  = 6.32\\\\\\or\\5\sqrt{15} \\\\

this is because when 40 is broken down into two numbers (one divisible to get out of the square root, and one not) you get 25 + 15 under the square root. we know that the square root of 25 is 5, so we can put 5 outside the root and leave 15 inside.

-------------- try the next problem, and if you don't understand, please reply back.

answer is for a) 5\sqrt{15}
