Step-by-step explanation:
Answer:
8 seconds
Step-by-step explanation:
Given :
h(t) = -16t2 + initial height
Initial height = 1024 feets
By the time it hits the ground, h(t) = 0
Equation becomes :
0 = - 16t² + 1024
Solve for t
-16t² = 1024
t² = 1024 / -16
t² = 64
t = √64
t = 8
Hence, it will take 8 seconds
D + 3r = 15
d = r + 3
r + 3 + 3r = 15
4r + 3 = 15
4r = 15 - 3
4r = 12
r = 12/4
r = 3 ....he bought 3 roses, at $ 3 per rose = $ 9 <==
d = r + 3
d = 3 + 3
d = 6....he bought 6 daisies, at $ 1 per daisy = $ 6
Answer:
400
Step-by-step explanation:
6/8 = 0.75 or 75% expected to respond favorably.
Margin of error 2.5%:
Lower bound: 0.75 - .025 = 0.725
Upper bound: 0.75 + .025 = 0.775
Range:
Lower bound: 8000 * 0.725 = 5800
Upper bound: 8000 * 0.775 = 6200
6200 - 5800 = 400
