Answer:
f(g(2))=84
Step-by-step explanation:
Step one:
Given data
f(x)= x*2 +3
g(x) = 4x + 1
Step two
Let us find g(2) first then we proceed to find f(g(2))
g(2)=4(2) +1
g(2)=8+1
g(2)=9
Since g(2)=9
f(g(2))=x*2 +3
f(g(2))=9*2 +3
f(g(2))=81+3
f(g(2))=84
between 3 and 4 would be 3.5cm
Answer:
-2/3 gallon/minute
Step-by-step explanation:
In three minutes the water volume has decreased by 2 gallons (7 less 5 is 2). The unit rate of decrease of the amount of water in the tank is thus:
- 2 gallons
------------------- = -2/3 gallon/minute
3 minutes
