From the graph shown it can be seen that the bridge is represented by a parabola with vertex of (5, 8) and roots of 1 and 9.
Recall that the vertex form of the equation of a parabola with vertex (h, k) is given by

Thus, the equation of the given graph in vertex form is given by

Also, recall that the equation of a parabola with roots, p and q, is given by

Thus the equation of the given graph can be given by

To get the value of a, we equate both equations and solve as follows:

Rate of change = (1350 - 750)/(2010 - 2000) = 600/10 = $60
Initial value = $750
Equation is y = 60x + 750; where y is the amount charged to customer and x is the number of years from 2000.
Answer:
D. 36 feet
Step-by-step explanation:
One yard is 3 feet
So you do 12*3
which equals 36 ft
