Given the time t = 2 seconds, simply plug in it to the equation.
h = - 16(2)² + 541
= - 16(4) + 541
= - 64 + 541
h = 477 feet
Answer:
from the similar triangles it will have the ratio is 3/5=15/x ; x=25
Answer:
y = 8.5
Step-by-step explanation:
7y - 4 = 9y +13 - 4y
First arrange to combine like terms.
7y - 4 = 9y - 4y + 13
7y - 4 = 5y + 13 Subtract 5y from each side
7y - 5y - 4 = 5y - 5y + 13
7y - 5y - 4 = 13
2y - 4 = 13 Add 4 to each side
2y - 4 + 4 = 13 + 4
2y = 13 + 4
2y = 17 Divide each side by 2
2y/2 = 17/2
y = 17/2 or 8 or 8.5
Answer:
b = -16.77
Step-by-step explanation:
We could get a quick estimate from b/8 = -2: b is approximately -16.
For an exact answer, multiply both sides by 7.8: b = -16.77
The function has been shifted to the right 3 units
