Step-by-step explanation:
Answer:
the domain of the function = [0,12]
Step-by-step explanation:
Given that:
f(t) = 60 t - 5t²
at time t = 0
f(0) = 60 (0) - 5(0)²
f(0) = 0
the differential of f(t) is:
f(t)' = 60 - 10t
for the maximum height
f'(t) = 0
i,e
60 - 10t = 0
60 = 10t
t = 60/10
t = 6
Now, t = 6,
f(6) = 60(6) - 5(6)²
f(6) = 360 - 180
f(6) = 180
Hence, after 6 seconds, the stone is noticed to have raise to 180 m and 180 m drop after 6 seconds.
Hence, the domain of the function = [0,12]
If Sheila can ride her bike 6000 meters in 15 minutes, then you can divide
6000 ÷ 15 to find how far she can ride in 1 minute.
6000 ÷ 15 = 400.
So, Sheila can ride her bike 400 meters in 1 minute.
To find how many meters she can ride in 2 minutes, multiply 400 by 2.
400 x 2 = 800.
Sheila can ride her bicycle 800 meters in 2 minutes.
