The vertex form is 
Step-by-step explanation:
The given equation 
is a parabola. The vertex of the parabola is of the form 
The parameters of the parabola are 
and 
The vertex of the x-coordinate is given by 
Thus, substituting the values of a and b in , we get,
Now, substituting 
in , we get,
Thus, the vertex is 
The equation of parabola to be in vertex form is 
where a is the coefficient of 
, h is vertex of the x-coordinate and k is the vertex of the y-coordinate.
Hence, 
and 
Thus, substituting the values in the equation of the vertex form,
Hence, the vertex form is
Answer:
The distance is 10.5 miles
Step-by-step explanation:
Mathematically; we want to calculate the distance between the two towns in the question
Distance = speed * time
15 minutes to hours is 15/60 = 1/4 hours
So the distance would be;
Distance = 42 mph * 1/4 = 10.5 miles
1/11 is half of 2/11. (1/11 + 1/11 = 2/11)
As 2/11 = 0.18, 1/11 must equal half of 0.18.
Half of 0.18 is 0.09. Thus the decimal for 1/11 is 0.09.
678 × 7 = 4,746 here go man you are smart lol
