PLEASE HELP Two identical rubber balls are dropped from different heights. Ball 1 is dropped from
a height of 131 feet, and ball 2 is dropped from a height of 272 feet. Use the
function f(t) = -16t2 + h to determine the current height, f(t), of a ball dropped from a
height h, over given time t.
When does ball 2 reach the ground? Round to the nearest hundredth.

9514 1404 393

  4.12 seconds

Step-by-step explanation:

Use the given initial height for Ball 2 to fill in that value in the function.

  f(t) = -16t² +272

You want to find t when f(t) = 0.

  0 = -16t² +272

  0 = -t² +17 . . . . . . . divide by 16

  t² = 17 . . . . . . . . . add t²

  t = √17 ≈ 4.123 . . . . take the positive square root

Ball 2 reaches the ground after 4.12 seconds.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

imma say 16%. sorry if its wrong. i'm doing the same stuff right now
