Answer:
Length = 5
Width = 21
Step-by-step explanation:
(x)(x + 16) = 105
x^2 + 16x = 105
x^2 + 16x - 105 = 0
(x - 5) x ( x + 21) = 0
x - 10 = 0
x = 5
x + 21 = 0
x = -21
Now that we have the zeroes.
We have to find the most viable one to put in.
Using -21 would not make sense, so we will use 5.
Plug it in:
x = 5
(5) (5 + 16) = 105
5 ( 21) = 105
The cylinder is symmetric across the plane

, so we need only consider half of the cut-out region.
This region can be parameterized by

with

and

. Then the area of this half is given by the surface integral



Doubling this gives a total area of 72.
Answer:
4 batches
Step-by-step explanation:
4.8/1.2 = 4
Answer:
B) 6 tan(35°)
Step-by-step explanation:
from the right angle tan° = opposite / adjacent
therefore tan (35°) = (x) / 6
by multiplying 6 to both sides
tan (35°) * 6 = (x) / 6 * 6
therefore (x) = 6 tan (35°)
6 = 1/13 (6-7)
Thats mostlikely wrong im sorry \(._.)/
