The altitude of a triangle is increasing at a rate of 2.5 2.5 centimeters/minute while the area of the triangle is increasing at a rate of 1.5 1.5 square centimeters/minute. at what rate is the base of the triangle changing when the altitude is 8 8 centimeters and the area is 84 84 square centimeters?

At that moment dB/dt=0

Step-by-step explanation:

The area of a triangle is given by

A=bh/2

A=area, b=base, h=height

If we differentiate over time:

(product differentiation)

we have that:

When H=8 and A=84 then B is equal to

Therefore

the answer

b. they are parallel and will never intersect.

the answer is 2/54
