Answer:
<u>z = -4</u>
Step-by-step explanation:
<u>Given</u> :
- x = -2
- y = -5
- z divides xy in the ratio 2 : 1 (m : n)
<u>Solving</u> :
- Take the section formula
- z = [my + nx] / [m + n]
- z = [2 x -5 + 1 x -2] / [2 + 1]
- z = -10 - 2 / 3
- z = -12 / 3
- <u>z = -4 </u>
For this case we have the following expression:
h (t) = -16t ^ 2 + 64t + 80
For t = 0 we have:
h (0) = -16 (0) ^ 2 + 64 (0) + 80
h (0) = -0 + 0 + 80
h (0) = 80 feet
Therefore the number 80 represents the initial height of the rocket
Answer:
the 80 in the expression represented:
the initial height of the rocket
