Given the function f(x) = √x-8 + 3 which of the following is the value of f(24)

kvasek [131]

Answer:

The answer is 7.

Step-by-step explanation:

You have to substitute the value of x into the function :

$f(x) = \sqrt{x - 8} + 3$

$f(24) = \sqrt{24 - 8} + 3$

$f(24) = \sqrt{16} + 3$

$f(24) = 4 + 3$

$f(24) = 7$

The velocity v of the flow of blood at a distance r from the central axis of an artery of radius R is given below, where k is th

andrew11 [14]

The average rate of blood flow is given by

$\displaystyle\frac1{R-0}\int_0^Rv(r)\,\mathrm dr=\frac kR\int_0^R(R^2-r^2)\,\mathrm dr$
$=\dfrac kR\left(R^2r-\dfrac13r^3\right)\bigg|_{r=0}^{r=R}$
$=\dfrac kR\left(R^3-\dfrac13R^3\right)$
$=\dfrac{2kR^2}3$
