Just divide 99.6 by 21...

Because you want to know how many meters per second..

99.6 / 21 = around 4.74 meters

so the rate of descent is around 4.74 meters

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}.
