Question

The altitude (height) of a triangle is increasing at a rate of 1 cm/min while the area of the triangle is increasing at a rate of 2 square cm per min. At what rate is the base of the triangle changing when the altitude is 10 cm and the area is 100 square cm?

Answer #1

The altitude of a triangle is increasing at a rate of 1 cm/min
while the area of the triangle is increasing at a rate of 2
cm2/min.
At what rate is the base of the triangle changing when the altitude
is 20 cm and the area is 160 cm2?

The
altitude of a triangle is increasing at a rate of 2.5 cm/min
while the area the triangle is increasing at a rate of 2.5 cm² per
minute. At what rate is the base of the triangle changing when the
altitude is 8.5 cm and the area is 94 cm² ?

The altitude (i.e., height) of a triangle is increasing at a
rate of 1.5 cm/minute while the area of the triangle is increasing
at a rate of 2.5 square cm/minute. At what rate is the base of the
triangle changing when the altitude is 11.5 centimeters and the
area is 87 square centimeters?

The height of a triangle is decreasing at a rate of 1 cm/min
while its area is increasing at a rate of 2 cm^2/min.
(a) What is the base of the triangle when its height is 10 cm
and its area is 100 cm^2?
(b) At what rate is the base of the triangle changing when its
height is 10 cm and its area is 100cm^2?

The altitude of a triangle is increasing at a rate of
1 centimeters/minute while the area of the triangle is increasing
at a rate of 5 square centimeters/minute. At what rate is the base
of the triangle changing when the altitude is 12 centimeters and
the area is 85 square centimeters?
________cm/min

the height of a triangle increases at a rate of 3 cm /
min while the area increases at a rate of 4 cm ^ 2 / min. At what
rate does its base change when the height is 10 cm and the area is
90 cm ^ 2

(a) The altitude of a triangle is increasing at a rate of 1
centimeters/minute while the area of the
triangle is increasing at a rate of 2 square centimeters/minute. At
what rate is the base of the
triangle changing when the altitude is 7 centimeters and the area
is 88 square centimeters?

The radius of a circular cylinder is increasing at rate of 3
cm/s while the height is decreasing at a rate of 4 cm/s.
a.) How fast is the surface area of the cylinder changing when
the radius is 11 cm and the height is 7 cm? (use A =2 pi r2 +2 pi
rh )
b.) Based on your work and answer from part (a),is the surface
area increasing or decreasing at the same moment in time? How do...

The radius of a cylinder is increasing at a rate of 3cm/min
while the height is decreasing at a rate of 10cm/min. What is the
rate of change of the volume of the cylinder when the height is
100cm and the radius is 20cm?
Please solve the question step by step
