Answer: Ann's distance from home staying is increasing the fastest from the 5th to the 6th minute

Step-by-step explanation: The slope from the 5th minute to the 6th minute is 40, meaning that she increased 40 mph in one minute. This increase is greater than any other time periods. At first, you might think that minute 0 to 1 is the greatest but the slope from minute 0 to 1 is actually 30 mph, so therefore my answer can be proven correct.

I need to find the volume for number 10
kumpel [21]

Using the diagonal dimension and the height we can solve for the diameter of the cylinder using the Pythagorean theorem.


x^2 + 9.5^2 = 19.3^2

x^2 + 90.25 = 372.49

x^2 = 372.49 - 90.25

x^2 = 282.24

x = √282.24

x = 16.8


Now we know the diamteer and height, we can calculate the volume using the formula V = pi * r^2 * h

r = 1/2 the diameter = 16.8/2 = 8.4

using 3.14 for pi

Volume = 3.14 * 8.4^2 * 9.5

V = 3.14 * 70.56 * 9.5

v = 3.14 * 670.32

v = 2104.8 cubic meters
