Answer:
Step-by-step explanation:
f(x)=(x²+20x+100) -3 because : 97 = 100 - 3
f(x) = (x+10)² -3 ....vertex form
30% can also be written as .3, which is easier to use in this case.
To find how many just sat around, multiply the number of people by the percentage of how many just sat around.
1400*.3=420
Given:
ratio of altitude height = 2/3
Required:
ratio of volume
Solution:
Assuming that the only difference that the cylinders has is the height, we can solve for the ratio of the volume.
The volume of a cylinder is equal to πr²×height.
ratio of volume = πr²×2/πr²×3
We cancel the pi and the r² since we assume that the cylinders have the same radius.By cancelling, we are left with:
ratio of volume = 2/3
