The work done by
is

where
is the given curve and
is the given parameterization of
. We have

Then the work done by
is


In order for the work to be 1, we need to have
.
Remember that

Thus, we can solve for x.
x + 22 = 90 - (2x - 7)
x + 22 = 97 - 2x
3x + 22 = 97
3x = 75
x = 25
20,809,204 is the answer because 20,000,000+800,000+9,000+200+4
Answer:
Neither.
Step-by-step explanation:
you are correct about the pattern, so it's not adding the same number and not multiplying by the same number. So it's neither.
y > 5x-1, because it is just a greater than sign, the shaded area would be to the left of a dotted line.
y ≤ x +3, because the sign is less than or equal to, the line is solid and the shaded area would be to the right.
Combine the shaded areas would make Graph B. the correct answer.
