Answer:
A. 2 feet long
Step-by-step explanation:
the weight starts at 0.5 lbs = 10 inches, and after that every extra 0.5 lb means it's 2 inches longer. so the last data point we have is 2.5 lbs = 18 in, so we can assume that 3.0 lbs = 20 in, 3.5 lbs = 22 in, and 4.0 lbs = 24 in, and 24 inches is equal to 2 feet
the inverse of y is =x+7
Step-by-step explanation:
y=5x-7
then solve for x
5x=y+7
x=(y+7)/5
then exchange x with y
y=(x+7)/5
( D. 3$ per lb ) 3 times 15 = 45
the answers are $105.54 and $105.35 to round down the highest you can go is to 4 to round up the lowest you can go is 5 so for example say you wanted to round down from 4 it would go to 0 and say you wanted to round up from 5 it would go to 10. 1, 2, 3, and 4 are qaulifications to round down. 5, 6, 7, 8, and 9 are qaulifications to round up
Work = force * displacement
= 50 N * 20 Meter
=1000 Newton meter = 1000 joule .
