What is the average rate of change for this function for the interval from x=3 to x=5?​
timofeeve [1]

Answer:

B

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [ a, b ] = [ 3, 5 ]

From the table of values

f(b) = f(5) = 32

f(a) = f(3) = 8

Hence

average rate of change = \frac{32-8}{5-3} = \frac{24}{2} = 12

A conical tent made of canvas has a base that is 34 feet across and a slant height of 12 feet. To the nearest whole unit, what i
tresset_1 [31]
Here you'll need to do some online research, using "area of a cone" as your search term.  There is a formula!  But it's complicated.

Once you've found this formula online, substitute 17 feet for r.  The height of the cone has to be calculated from the slant height (these are not the same):

(slant height)^2 = (12 feet)^2 = r^2 + h^2, where h is the actual height of the cone.

The area of the base is pi*r^2, or pi*17^2 square feet.
