Answer:

f(x) = x^3 - 2(x)^2+3(x)-1

Step-by-step explanation:

Since h(x) is the combination of function f and g, you have to seprate g(x) from f(x).

To do this, you subsitute x for each and every (8-4x) because g(x)=(8-4x)

h(x) = (8-4x)^3 - 2(8-4x)^2+3(8-4x)-1 so

f(x) = x^3 - 2(x)^2+3(x)-1

BigorU [14]

Answer:

52 miles/week (12 more miles per week)

Step-by-step explanation:

In order to know the miles per week with this increasement, we'll use the rule of 3, assuming that 40 miles is the 100% innitially so:

If:

40 miles --------->100%

X miles ----------> 30%

Solving for X we have the following:

X = 30 * 40 / 100 = 12 miles

So, if Adam wants to increase his weekly mileage by 30%, he needs to run 12 more miles, and that makes a total of 52 miles/week
