Answer:
2,400 foot-pounds
Step-by-step explanation:
Say at any instant x is length of Rope
Work done in lifting rope by dx amount will be:
dw = -(2.5x + 10)dx
w = -(40)∫(2.5x+10)dx
w = (2.5(40)^2) / 2 + 10(40)
w = 2000 + 400
w = 2,400 foot-pounds
For this case we have the following numbers:
3.1 × 10-2
2.01 × 10-3
4.2 × 10-5
1.03 × 10-1
2.32 × 10-4
To order the numbers, we must look at the exponent. The greater the exponent, the greater the number.
We have then that the order of greatest to least is:
1.03 × 10-1
3.1 × 10-2
2.01 × 10-3
2.32 × 10-4
4.2 × 10-5
Answer:
Part 5) Option b
Part 6) Option d.
Step-by-step explanation:
Part 5) we know that
The area of a square is equal to
where
b is the length side of the square
we have
substitute
Solve for b
take square root both sides
Remember that
substitute
Applying property of exponents
Part 6) we know that
The volume of a cube is equal to
where
b is the length side of the cube
we have
substitute
Solve for b
take cubic root both sides
Remember that
substitute
Applying property of exponents
