V=hpir²
h=8
d=2r
d/2=r
5/2=2.5=r

V=8pi2.5²
V=8pi6.25
V=50pi
aprox pi=3.14

V=50 times 3.14
V=157 in³

This table shows values represented by an exponential function.

Bad White [126]

Answer:

$a = 2 , f(2)=9$

$b = 4 , f(4)=64$

And replacing the data into the average rate formula we got:

$m = \frac{64-9}{4-2}= 27.5$

And then the best answer for this case would be:

C. 27.5

Step-by-step explanation:

For this cae we know that the average rate of change of a function is given by this general expresion:

$m = \frac{f(b) -f(a)}{b-a}$

For this special case from the info of the table we have:

$a = 2 , f(2)=9$

$b = 4 , f(4)=64$

And replacing the data into the average rate formula we got:

$m = \frac{64-9}{4-2}= 27.5$

And then the best answer for this case would be:

C. 27.5

What is f(5) if f(1)=3.5 and f(x+1)=5\2 f(x)

katen-ka-za [31]

Answer:

f(5) = 136.71875‬

Step-by-step explanation:

f(5) if f(1)=3.5 and f(x+1)=5\2 f(x)

f(2) = (5/2)* f(1) = (5/2)* 3.5 = 8.75

f(3) = (5/3)*f(2) =(5/2) * 8.75

f(4) = (5/3)*f(3) =(5/2)*(5/2) * 8.75

f(5) = (5/3)*f(4) = (5/3)*(5/2)*(5/2) * 8.75

f(5) = (5/2)^4 * 3.5 = (625/16) * 3.5 = 136.71875‬

f(5) = 136.71875‬
