Answer:
5ff5yvy hh h
Step-by-step explanation:
ctvtvh j h h h j
When the penny hits the ground, h will = 0.
So: Set h(t) = 0 = -4.9t^2 + 0t + 150 m
Then 4.9t^2 = 150, and so t^2 = sqrt(150 / 4.9) = plus or minus 5.53 sec.
We can use only the positive root, as we're measuring time.
t = 5.5 sec (answer)
X ÷ 9 = 6
Multiply both sides by 9
x ÷ 9 • 9 = 6 • 9
x = 54
No, so lets simplify it.
20/100 =
20/20 = 1
100/5 = 20
Answer: 1/20
