Harley is riding her bicycle 9.88 miles from her house to work. If she rides at a speed of 13 miles per hour, how long will it t
1 answer:
It would take Harley 46 minutes to arrive at work.
Step-by-step explanation:
Given,
Distance from house to work = 9.88 miles
Speed of bicycle = 13 mph
Distance = Speed*Time
Time =
Time =
Time = 0.76 hour
We know that 1 hour = 60 minutes
0.7 hours = 60*0.76
0.7 hours = 45.6 minutes
Rounding off to nearest whole minute
0.7 hour = 46 minutes
It would take Harley 46 minutes to arrive at work.

Answer:
Step-by-step explanation:
An equation in the vertex form is written as
Where the point (h, k) is the vertex of the equation.
For an equation in the form the x coordinate of the vertex is defined as
In this case we have the equation .
Where
Then the x coordinate of the vertex is:
The y coordinate of the vertex is replacing the value of in the function
Then the vertex is:
Therefore The encuacion excrita in the form of vertice is:
To find the coefficient a we substitute a point that belongs to the function
The point (0, -1) belongs to the function. Thus.
<em>Then the written function in the form of vertice is</em>
