Need with this . given the following functions: f(u)=tan(u) and g(x)=x^9. find:

f′(g(x))=
(f∘g)′(x)=

i found the other functions, just need with these two.

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
