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
![\int\limits {p'(x)} \, dx =\int\limits {60x^3+90x^2} \, dx](https://tex.z-dn.net/?f=%5Cint%5Climits%20%7Bp%27%28x%29%7D%20%5C%2C%20dx%20%3D%5Cint%5Climits%20%7B60x%5E3%2B90x%5E2%7D%20%5C%2C%20dx)
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:
-13 2/3
Step-by-step explanation:
-5 5/6 5x6= 30 4x5= 20
+ 20/30= 2/3
-8 4/5
----------- -5 + -8 = -13
-13 2/3
hope this helps
D. 28
this is because 48 divided by 12 is 4, 4 times 7 is 28.
183.9 millimeters is the answer
