The practical dominion is from t = 0, when the ball starts motion until the time when the ball hits the ground.
To find the time when the ball hits the ground solve the equation:
h(t) = 0
=> -16t^2 + 68t = 0
Factor: t(-16t + 68) = 0 => t = 0 and -16t + 68 = 0
=> 16t = 68
=> t = 68/16
=> t = 4.25
So, the practical domain is 0 ≤ t ≤ 4.25 s.
Which also may be represented by t ∈ [0, 4.25s]
Answer:
Step-by-step explanation:
(-3/4)^-4 = (-4/3)^4 = (4/3)^4
Answer:
11.25 seconds
Step-by-step explanation:
first, we need to figure how how far william can run per second
we can find this by 40 ÷ 4.5
= 8.889 per second
so we know that 8.889 • s (seconds) = 100
8.889s = 100 divide both sides by 8.889
s = 11.25 seconds
Answer:
