I WILL GIVE BRAINLIEST TO WHOEVER ANSWERS!!! EVEN IF IT IS WRONG!!!!! Mariano is standing at the top of a hill when he kicks a soccer ball up into the air. The height of the hill is h feet, and the ball is kicked with an initial velocity of v feet per second. The height of the ball above the bottom of the hill after t seconds is given by the polynomial −16t2 + vt + h. Find the height of the ball after 4 seconds if it was kicked from the top of a 25 foot tall hill at 72 feet per second.

Answer:

  57 feet

Step-by-step explanation:

A formula is given for the height of the ball, and all of the values necessary to evaluate the formula are also given. The height of the ball after 4 seconds is found by substituting the given values into the formula and doing the arithmetic.

__

  height = -16t² +vt +h . . . . . for t=4, v=72, h=25

  height = -16(4²) +72(4) +25 = -256 +288 +25 = 57

The height of the ball is 57 feet above the bottom of the hill 4 seconds after it was kicked.
