H = -16t2 + 64t + 80 Determine the maximum height of the rocket. Show your work.

1 answer:

3 0

H = -16t² + 64t + 80 (:16)
H = -t² + 4t + 5
/\ = b²-4ac
/\ = 4²-4.(-1).5
/\ = 16+20
/\ = 36
Yv = -/\ / 4a
Yv = -36/4.(-1)
Yv = -36/-4
Yv = 9

What property was applied to solve the equation below? Negative StartFraction 3 over 8 EndFraction x = 48 Negative StartFraction

Soloha48 [4]

Multiplication property of equality

Step-by-step explanation:

We are given that the equation

$-\frac{3}{8}x=48$

We have to find the property which was applied to solve the equation.

$-\frac{3}{8}x=48$

Reason: Given

Multiply by -8/3 on both sides

$-\frac{8}{3}\times -\frac{3}{8}x=-\frac{8}{3}\times 48$

By using multiplication property of equality.

$x=\frac{-384}{3}$

After simplification

$x=-128$
