Circumference = 2πr = 27 cm
= 2 × 3.14 × r = 27
= 3.14 × r = 27/2
so, r = 
× 
= 4.2 cm

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)
Step-by-step explanation:
two answers either
x = 8
or
x = -1
Answer:
12a^3-6a^2+2a+9
Step-by-step explanation:
12a^3-6a^2-2a+7+4a+2
12a^3-6a^2+2a+7+2
12a^3-6a^2+2a+9
