Question

Allie went to space camp and her final project was a rocket launch. She is being graded on the maximum height that her rocket reaches. Here is her grading rubric: For an A>30 ft high, for a B >25 ft high, for a C>20 ft high, for a D>15 ft high, anything less than 15 ft high Allie would receive an F. What grade did Allie receive? Here is a function of the path that Allie's rocket took

Answer 1

This looks hard so i think someone else could help

Answer 2

Explanation:

Given formula: y= -4x^2+24x+2

max height given by the derivative of above formula, being equal to zero

0 = -8t +24

8t = 24

t = 3

at 3.0000000 seconds there will be a max in the rockets height ( that was nice of who ever figured out this formula to make it so easy )

y = height

y= -4*3^2+24*3+2

h = -36 +72 +2

h = 38 feet? we were not told if the formula is in feet. ( assume that it is , but double check it)

Nice ! so Allie gets an A :) A for Awesome Allie, :DDDD
