Answer:
125600
Step-by-step explanation:
Please specify your answer better next time.
1. If you just want to replace all the "x" with 10, then it would be 403.140100
2. If x is a variable, then 4(10)(3.14)(10)(100)=125,600
We want to find the work done by lifting a book a given distance.
The answer is 200 N*m
We know that the book weighs 100 Newtons and that we lift it a distance of 2 meters.
Remember that the work needed to lift an object of mass M to a height H is:
W = M*g*H
where g is the gravitational acceleration.
Knowing that:
weight = M*g
We can replace the things we know to get the work:
W = 100N*2m = 200 N*m

To find the product of two numbers, you multiply them
1/2*2/5
We have to multiple the numerators, and multiply the denominators
Numerators: 1*2=2
Denominators: 2*5=10
So the answer is 2/10 or 1/5
Hope this helps!
Answer:
A) 0
Step-by-step explanation:
The actual definition of parallel lines are lines that never intersect, so the answer is 0
We know that:
Substituting known values, we have:
