Answer:
he airplane’s altitude was 400 feet at 8:00 a.m. is the best describes
the meaning of the statement h(0)=400 ⇒ answer a
Step-by-step explanation:
The altitude of an airplane is described by a certain function h ,
where h(t) is the altitude in feet of the airplane t minutes after
8:00 a.m.
That means:
1. The altitude of the airplane can be calculated by using this function
at any time after 8:00 a.m.
2. At 8.00 a.m. the value of t = 0
3. h(0) is the initial altitude of the airplane
∵ The altitude of the airplane h at any time t after 8:00 a.m. can be
calculated from the function h(t)
∵ At 8:00 a.m. t = 0
∵ h(0) = 400
∴ The altitude of the airplane at t = 0 is 400
∴ The initial altitude of the airplane is 400
The airplane’s altitude was 400 feet at 8:00 a.m
