2x+3y=60 solve for x...
x=(60-3y)/2
p=xy^3, using x from above:
p=y^3(60-3y)/2
p=(60y^3-3y^4)/2
dp/dy=(180y^2-12y^3)/2
dp/dy=90y^2-6y^2
dp/dy=0 when:
90y^2-6y^3=0
6y^2(15-y)=0, we know y>0 so
y=15, since x=(60-3y)/2
x=7.5
(We solved it this way because otherwise you get quartic equations and cubic derivatives, yuck :P)
By factor theorem, f(-4)=7,therefore x+4 is not a factor of f..and remainder when decided by x+4 is 7
Answer:
The answer is the Kiki word problem
Step-by-step explanation:
It’s True liner y= 3 - 10x
I think it’s 135
12x15=180
180 divided by 4/3 or 1 1/3 = 135
