Answer:
The sprinter
Step-by-step explanation:
Change cyclist to same units as sprinter (m/s)
20 km = 20x1000 m = 20000 m
1 hour = 60 minutes = 60 x 60 = 3600 sec
So 20 km/hr = 20,000 m / 3600 sec = 5.6 m/s
The sprinter is faster as he travels at 8 m/s.
(Similarly if you change the sprinter's speed into km/hr
you should get 28.8 km/hr)

Answer:
i really dont know
Step-by-step explanation:
this is confusing
Well.. for the equation x= 3.5, let's take a look at its values
so.. notice.. no matter what "y" is, "x" will always be 3.5,
so is really just a horizontal line, thus, look at the picture below
A vertical stretching<span> is the </span>stretching<span> of the graph away from the x-axis.
It means you simply need to multiply the scale factor with the x-values.
</span>If point H is located at <span>(-2, 0),and the scale factor is 2,then the stretch would be (-2*2.5,0)
Hence,the new point will be:
A.(-5,0).
