1 km = 0.62 miles....so 26 km = (26 * 0.62) = 16.12 miles
If <em>a</em> is fixed and <em>b</em>,<em>c</em> are unknowns then the equation <em>b</em>+<em>c</em>=10-<em>a</em> has 11-<em>a</em> solutions. They are pairs (b,c): (0,10-a), (1,9-a), (2,8-a), ... (10-a,0). As <em>a</em> runs from 0 to 10 we have total number of solutions (11-0)+(11-1)+...(11-1)=11+10+...+1=(1+11)*11/2=66.
Answer:
C
Step-by-step explanation:
We want to determine the vertex of the quadratic equation:

Recall that the vertex is given by the formulas:

In this case, <em>a</em> = -1, <em>b</em> = 2, and <em>c</em> = 1.
Determine the <em>x-</em>coordinate of the vertex:

To determine the <em>y-</em>coordinate, evaluate the function at <em>x</em> = 1:

In conclusion, the vertex of the quadratic equation is (1, 2).
Hence, our answer is C.
