Answer:
A) 
Step-by-step explanation:
The equation of a circle is
where
is the center and
is the radius. If
and
, then:

Therefore, the equation of the circle is 
G(x) is a quadratic function with a parabolic graph that opens up and has vertex at (0,0). If we dilate this vertically by a factor of 6, we get h(x) = 6x^2.
If we translate the graph of h(x) 1 unit up and 4 units to the right, we get
k(x) = 6(x-4)^2 + 1.
A is more because 1/4 is equal to 2/8 and 2/8 is less than 7/8 so you would have more than a minute
B is three minutes 2/8 goes into 7/8 three times
Answer:
yous should multiply it by 3.6;
0.12*3.6=0.432 km/h
