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,   :

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
