472 to the nearest 100 is 500
Answer:
h(t) = 40,000 - 1,500t
Step-by-step explanation:
Let h(t) be the height of the airplane after t minutes.
h(t) = 40,000 - 1,500t
I think it would be like how many times does 5 go into 48.. and that would be 9 and 3/5
Answer:

Step-by-step explanation:
The given function is
f(x) = 4x
As we know
f(x) = y, which implies x= 
Therefore,
y = 4x
x = 
as x= 
So,

replacing y by x in the above expression

So our inverse function is 
2-(-x+5)
2+x-5
x-3
I decided to included the steps just in case you needed them
