Answer:
A
outdoor temperature as a function of time
Step-by-step explanation:
If you put the temperture as a function of time, every passing hour or minute the tempurture decreases resulting in a decrease in your function.
This can also be shown in a graph were the tempuerture is the x and the time is the y. Each hour that passes the temputure goes down until night falls and the temputure reaches a constant rate of tempurture
8*60 minutes = 480
4*60 minutes = 240
480-240=240
240 miles
Im unsure about g(f(4)) though.
Answer:
d≈7.07
Step-by-step explanation:
Using the formulas
P=4a
d= \sqrt{2} a
Solving ford
d= \sqrt{2} P/4=2·20
/4≈7.07107
