The volume of water flowing through a pipe varies directly wlth the square of the radius of the pipe. If the water flows at a ra

Rashid [163]

Answer:

A

Step-by-step explanation:

Volume varies directly with the square of the radius, so:

V = k r²

When V = 80, r = 4.

80 = k (4)²

k = 5

V = 5r²

When r = 3:

V = 5 (3)²

V = 45

The flow is 45 L/min.

Use f(x)=(2x+1)/(3x-2) and g(x)=5x-1 to find <br> (gof)(x)

Orlov [11]

Answer:

From the functions f(x) and g(x) we have $(g\circ f)(x)=\frac{7(x+1)}{3x-2}$

Step-by-step explanation:

Given that the functions f is defined by $f(x)=\frac{2x+1}{3x-2}$

and g is $g(x)=5x-1$

To find the $(g\circ f)(x)$ :

$(g\circ f)(x)=g(f(x))$

$=g(\frac{2x+1}{3x-2})$

$=5(\frac{2x+1}{3x-2})-1$

$=\frac{10x+5}{3x-2}-1$

$=\frac{10x+5-1(3x-2)}{3x-2}$ ( by using the distributive property )

$=\frac{10x+5-3x+2}{3x-2}$

$=\frac{7x+7}{3x-2}$ ( adding the like terms )

$=\frac{7(x+1)}{3x-2}$

Therefore $(g\circ f)(x)=\frac{7(x+1)}{3x-2}$ .
