For items 1-5
A 10-ft ladder is leaning against a house on flat ground.
The house is to the left of the ladder. The base of the
ladder starts to slide away from the house. When the base
has slid to 8 ft from the house, it is moving horizontally at
the rate of 2 ft/sec. How fast is the ladder's top sliding
down the wall when the base is 8 ft from the house?
Assuming:
x is the distance between the bottom of the ladder and the
wall
y is the distance between the top of the ladder and the
wall
Relation of x and y using Pythagorean theorem is: x^2 +
y^2 = 64
