Question

I need help I have searched everywhere and nothing

Answer 1

Answer:

See attached

Step-by-step explanation:

All answers in one graph, refer to attached

The function we need is

• C(x) = 100(2*5280 - x) + 180$\sqrt{800 +x^2}$, where 2*5280= 2 miles

Table included as well

The vertex is about x = 19 ft which corresponds the minimum cost

Any other value, including negative reveal greater cost

• Note. there is a bit confusion over 2 miles or 2000 ft, but the graph is going to be same in shape and vertex for x, the value for cost will be different
