Answer:
Part A:
P(x)=15x^4+30x^3-50
Part B:
P(4)=$4270
Step-by-step explanation:
Part A:
In order to find the profit function P(x) we have to integrate the P'(x)
P'(x)=x(60x^2+90x)
P'(x)=60x^3+90x^2

P(x)=15x^4+30x^3+C
when x=0, C=-50
P(x)=15x^4+30x^3-50
Part B:
x=4
P(x)=15x^4+30x^3-50
P(4)=15*4^4+30*4^3-50
P(4)=$4270
Profit from selling 400 pounds is $4270
Answer:
Step-by-step explanation:
All you need to do is simplify 5-8 and it doesn't simplify any more so your ratio would be 5 to 8
455 cubic centimeters =
455 milliliters
A 90º degree angle is a right angle. Anything below is an acute angle and anything more than 90º is an obtuse angle.
