Answer:
Step-by-step explanation:
Hooke's Law applies here, which is a linear relationship. It would be easier to solve this using proportions with N of force on the top and the amount of stretch in cm on the bottom. Set up with our unknown, the number of cm:
and cross multiply:
20x = 300 so
x = 15 cm
Answer:
11) a or d 12) b
Step-by-step explanation:
sorry, I don't feel like looking at number 11 properly I'm half asleep
V =
where r is radius and h is height
so when radius is (x+8) and height is (2x+3),
volume =
15+5•y/2
15+5•4 / 2
15+20 / 2
15+10
=25
The formula for this is 2
