Answer:
Perpendicular ⇒
m = -1/-4 = 1/4
g(x) = (1/4)x + b
3/4 = (1/4)(5) + b
b = -1/2
g(x) = (1/4)x - 1/2

Answer:

Step-by-step explanation:
A road is perpendicular to a highway leading to a farmhouse d miles away.
An automobile passes through the point of intersection with a constant speed
= r mph
Let x be the distance of automobile from the point of intersection and distance between the automobile and farmhouse is 'h' miles.
Then by Pythagoras theorem,
h² = d² + x²
By taking derivative on both the sides of the equation,




When automobile is 30 miles past the intersection,
For x = 30

Since 
Therefore,
