a) 1/2
b) 250
Step-by-step explanation:
The start of the question doesn't matter entirely, although is interesting to read. What we are trying to do is find the value for such that is maximized. Once we have that , we can easily find the answer to part b.
Finding the value that maximizes is the same as finding the value that maximizes , just on a smaller scale. So, we really want to maximize . To do this, we will do a trick called completing the square.
.
Because there is a negative sign in front of the big squared term, combined with the fact that a square is always positive, means we need to find the value of such that the inner part of the square term is equal to .
.
So, the answer to part a is .
We can then plug into the equation for p to find the answer to part b.
.
So, the answer to part b is .
And we're done!
In the diagram, P1P2 and Q1Q2 are the perpendicular bisectors of AB and BC, respectively. A1A2 and B1B2 are the angle bisectors of ∠A and ∠B, respectively <span>the center of the circumscribed circle of ΔABC is P </span><span>because both perpendicular bisectors go through the center

Answer=C
Let's first solve for the volume of the cube
V=s³
V=9³
V=729cm³
1 liter is 1000cm³
1L=1000cm³
1L x L
_______ = _______
1000cm³ 729cm³
Cross multiply
1000x=729
divide both sides by 1000
x=0.729L
Answer=0.729L
