Answer:
They would have the bike for 1.7 hours
Step-by-step explanation:
The bike is rented at a charge of $5 for every half an hour,this can be expressed as:
$5 per 0.5 hours, to calculate the time one will have the bike if they pay $17
The amount of paid=Standard Rate per 1/2 of an hour/Number of hours
where;
The amount paid=$17
Standard Rate per 1/2 an hour=$5/0.5
Number of hours
Replacing;
n=(17×0.5)/5=1.7 hours

Given:
The equation of a quadratic function is:

To find:
The equation of the axis of symmetry for the given function.
Solution:
If a quadratic function is  , then the equation of the axis of symmetry is:
, then the equation of the axis of symmetry is:
 ...(i)
        ...(i)
We have,

Here,  . So, the equation of axis of symmetry by using (i), is
. So, the equation of axis of symmetry by using (i), is
 
 
 
 
 
 
Therefore, the correct option is C.
