Allie went to space camp and her final project was a rocket launch. She is being graded on the maximum height that her rocket re

aches. 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

This looks hard so i think someone else could help

Answer:

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,   :DDDD

What is the midpoint of the segment of the segment that would be created between points L and N on a graph?
il63 [147K]

Option A:

Midpoint of LN = (2, 3)  

Solution:

In the given graph we can find the coordinates of L and N.  

Coordinates of L = (–2, 3)

Coordinates of N = (6, 3)

Here, x_{1}=-2, x_{2}=6, y_{1}=3, y_{2}=3

Let us find the midpoint of the segment LN.

<u>Midpoint formula:</u>

$\text { Midpoint }=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)

                \begin{aligned}&=\left(\frac{-2+6}{2}, \frac{3+3}{2}\right)\\&=\left(\frac{4}{2}, \frac{6}{2}\right)\\&=(2,3)\end{aligned}

Midpoint of LN = (2, 3)  

Option A is the correct answer.  

Hence the coordinates of the midpoint of the line segment LN is (2, 3).

What is the volume of the triangular prism shown below ?
jekas [21]

Answer:

B

Step-by-step explanation:

The volume (V) of a triangular prism is

V = area of triangular end × length

area of Δ = \frac{1}{2} bh

where b is the base and h the perpendicular height

here b = 8 and h = 5, so

area = 0.5 × 8 × 5 = 20 units²

the length of the prism is 10, hence

V = 20 × 10 = 200 units³
