Answer:
C, 6!
Step-by-step explanation:
so h(x) is 21
21=2x+9
12=2x
x is 6
The sequence is times 2 minus 2
3 x 2 = 6 - 2 = 4
10 x 2 = 20
20 - 2 = 18
Answer:
try using the point (1,13)
Step-by-step explanation: I pulled up and online graph to help and the distance from A to B is 7/2. So then you would do B, plus 7/2. If that's wrong, I'm sorry, but i tried.
The formula for the vertical height, h, attained with a vertical take off speed of u is
u² - 2gh = 0
where
g = 9.8 m/s², acceleration due to gravity.
Because h = 1.29 m, therefore
u² = 2*9.8*1.39 = 27.244
u = 5.2196 m/s
Also, the time of flight, t, required when the vertical take-off speed is u is given by
ut - 0.5gt² = 0.
Therefore
5.2196t - 0.5*9.8*t² = 0
5.2196t - 4.9t² = 0
t(5.2196 - 4.9t) = 0
t = 0, or t = 5.2196/4.9 = 1.0652 s
t = 0 corresponds to take-off.
t = 1.0652 s corresponds to landing.
The hang time is 1.0652 s.
Answer:
Take-off speed = 5.22 m/s (nearest hundredth)
Hang time = 1.065 s (nearest thousandth)
