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

Step-by-step 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,   :

the image of (6, 9) under a dilation is (4, 6). the scale factor is

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
