For the first three you need to find volume, so the formula for volume is b*w*h. base*width*hight. so multiply all three numbers together and you will find your answer.
Answer:
a^4+2ab^2+b^4+a^16+2ab^8+b^16
Step-by-step explanation:
(a^2+b^2)^2+(a^8+b^8)^2
(a^2+b^2)^2=(a^2+b^2)(a^2+b^2)
=a^2(a^2+b^2)+b^2(a^2+b^2)
=a^4+(ab)^2+(ba)^2+b^4
=a^4+2ab^2+b^4
(a^8+b^8)^2=(a^8+b^8)(a^8+b^8)
=a^8(a^8+b^8)+b^8(a^8+b^8)
=a^16+(ab)^8+(ba)^8+b^16
=a^16+2ab^8+b^16
(a^2+b^2)^2+(a^8+b^8)^2=(a^4+2ab^2+b^4)+(a^16+2ab^8+b^16)
the answer is a^4+2ab^2+b^4+a^16+2ab^8+b^16
i think it is simplified answer

Answer:
The value of r to have maximum profit is 3/25 ft
Step-by-step explanation:
To find:
The size of the sphere so that the profit can be maximized.
Manufacturing cost of the solid sphere = $500/ ft^3
Selling price of sphere (on surface area) = $30 / ft^2
We see that the manufacturing cost dealt with he volume of the sphere where as the selling price dealt with the surface area.
So,
To maximize the profit (P) .
We can say that:
⇒
⇒
⇒
⇒
Differentiate "" and find the "" value then double differentiate "", plug the "" values from to find the minimum and maximum values.
⇒
⇒
Finding r values :
⇒
Dividing both sides with 240π .
⇒ ⇒
⇒ and
To find maxima value the double differentiation is :
⇒ ...first derivative
Double differentiating :
⇒ ...second derivative
⇒
Test the value r = 3/25 dividing both sides with 240π
⇒
⇒
⇒
It passed the double differentiation test.
Extra work :
Thus:
⇒
⇒
⇒
Finally r =3/25 ft that will maximize the profit of the manufacturing company.
