the distance d (in yard) of the first tower on a bridge from the road and the height h (in inches) above the road of a bridge is modeled by equation d^2 -39d + 324=h. At the first tower, if the driver of a car is looking down at the road from the bridge, how far away could the tower be from the road.​

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

4y - 6 + y^2 - 9 = y^2 + 4y - 15
