The number 'n' of cars produced at a certain factory in 1 day after 't' hours of operation is given by n(t)=100t-5t^2, 0< or equal t < or equal 10. if the cost 'c' (in dollars) of producing 'n' cars is c(n)=15,000+8000n, find the cost 'c' as a function of the time 't' of operation of the factory then interpret c(t) when t=5 hours as a new function.

We know that:

So first we need to substitute the next equation in the C(N) equation

And therefore we have:

Finally we replace at t = 5 in the equation above and we have:

The interpretation is that after 5 hours of operation, we have wasted 3015000 dollars producing cars.  

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

answer: 10 turtles

step-by-step explanation: as turtles have four legs so 4.10=40 therefore birds are 4 which sue counted
