Question 1015636: The president of a major housing construction firm reports that the number of construction jobs (in millions) created is given by N(x)=1.42x where x denotes the number of housing starts. Suppose the number of housing starts in the next t months is expected to be x(t)= 7(t+10)^2 / (t+10)^2+2(t+15)^2 million units/year.
a) Find an expression for the number of jobs created per month in the next t months.
b) How many jobs will have been created 6 months from now?

The president of a major housing construction firm reports that the number of construction jobs (in millions) created is given by N(x)=1.42x where x denotes the number of housing starts. Suppose the number of housing starts in the next t months is expected to be x(t)= 7(t+10)^2 / (t+10)^2+2(t+15)^2 million units/year.
a) Find an expression for the number of jobs created per month in the next t months.
N(t) = 1.42[7(t+10)^2 / (t+10)^2+2(t+15)^2] million units/year
------
b) How many jobs will have been created 6 months from now?
N(6) = 1.42 [7(16^2)/[16^2+2*21^2]]
etc.
