Answer:
E
Step-by-step explanation:
because it makes sense
For the derivative tests method, assume that the sphere is centered at the origin, and consider the
circular projection of the sphere onto the xy-plane. An inscribed rectangular box is uniquely determined
1
by the xy-coordinate of its corner in the first octant, so we can compute the z coordinate of this corner
by
x2+y2+z2=r2 =⇒z= r2−(x2+y2).
Then the volume of a box with this coordinate for the corner is given by
V = (2x)(2y)(2z) = 8xy r2 − (x2 + y2),
and we need only maximize this on the domain x2 + y2 ≤ r2. Notice that the volume is zero on the
boundary of this domain, so we need only consider critical points contained inside the domain in order
to carry this optimization out.
For the method of Lagrange multipliers, we optimize V(x,y,z) = 8xyz subject to the constraint
x2 + y2 + z2 = r2<span>. </span>
12 because the 23 3/8 is rounded down and the 11 2/9 is rounded down as well
So using a calculator this question is really easy 125,000x 1.35 ^10 =.

Easy.
7x + 2 = 2
7x = 2 - 2
7x = 0
x = 0 / 7
x = 0
Verify this by putting x = 0 ...
7 ( 0 ) + 2 = 2
0 + 2 = 2
2 = 2
Hence, "0" is the final answer.
Hope helps ........
