I need help with this question

1 answer:

7 0

28 laps/hour

You divide 35 by 1.25, and you get 28.

Another way is to look at it as 5/4. So 35 divided by 5 gives you 7 laps per 1/4 hour. Then 7 times 4 gives you 28 laps per hour.

$\bf \begin{cases}
g(x)=2x\\
h(x)=x^2+4
\end{cases}\qquad 
\begin{array}{llll}
(h\circ g)(x)\implies h[~~g(x)~~]\\\\
(h\circ g)(-5)\implies h[~~g(-5)~~]
\end{array}\\\\
-------------------------------\\\\
g(-5)=2(-5)\implies g(-5)=-10
\\\\\\
h[~~g(-5)~~]\implies h[~~-10~~]\implies h(-10)=(-10)^2+4
\\\\\\
h(-10)=100+4\implies h(-10)=104$

m = 6°
