Answer:
A
Step-by-step explanation:
The two angles add up to 90 degrees
Answer:
45°
Step-by-step explanation:
Well, compared to 90°, it looks like it's just smaller, but not too small. It couldn't be 15° degrees, or 60°, as it was probably too much. I Don't think it's 30° either, because it looked bigger than what a 30° angle would be.
Hope it helped!

Answer:
the answe is 100.53088
Step-by-step explanation:
You multiply 3.14159 or pi by the 32, which is the answer, and it gives you 100.53088
Looks like

The solid described by
is the interior of the region bounded by the paraboloid
and the plane
. Call this region
.
By the divergence theorem,

The divergence is

so that the surface integral reduces to

or in cylindrical coordinates,

What matters is the base for the exponentiation to tell if its increasing or decreasing. Among positive numbers, smaller than 1 means decreasing, bigger than one means increasing. That's because for each increase of 1 in x we get another factor of the base. If it's bigger than 1 that's growth.
There are no negative bases here, but it's similar -- less than -1 (bigger in absolute value) grows, even though it oscillates back and fourth between positive and negative.
It's blurry but I see bases of 3, .6, .74, 1.3
3: growth
.6: decay
.74: decay
1.3: growth
