Question

At noon, ship A is 150 km west of ship B. Ship A is sailing east at 35 km/h and ship B is sailing north at 30 km/h. How fast is the distance between the ships changing at 4:00 PM?

Gravel is being dumped from a conveyor belt at a rate of 30
ft^{3}/min, and its coarseness is such that it forms a pile
in the shape of a cone whose base diameter and height are always
equal. How fast is the height of the pile increasing when the pile
is 8 ft high? (Round your answer to two decimal places.)

A ladder 10 ft long rests against a vertical wall. If the bottom of the ladder slides away from the wall at a rate of 0.6 ft/s, how fast is the angle between the ladder and the ground changing when the bottom of the ladder is 8 ft from the wall? (That is, find the angle's rate of change when the bottom of the ladder is 8 ft from the wall.)

Boyle's Law states that when a sample of gas is compressed at a
constant temperature, the pressure *P* and volume *V*
satisfy the equation *PV* = *C*, where *C* is
a constant. Suppose that at a certain instant the volume is 200
cm^{3}, the pressure is 160 kPa, and the pressure is
increasing at a rate of 40 kPa/min. At what rate is the volume
decreasing at this instant?

Answer #1

(A)At noon, ship A is 140 km west of ship B. Ship A is sailing
east at 25 km/h and ship B is sailing north at 20 km/h. How fast is
the distance between the ships changing at 4:00 PM?
(b) If a snowball melts so that its surface area decreases at a
rate of 5 cm2/min, find the rate at which the diameter
decreases when the diameter is 9 cm.

At noon, ship A is 120 km west of ship B. Ship A is sailing
east at 20 km/h and ship B is sailing north at 15 km/h. How fast is
the distance between the ships changing at 4:00 PM?
km/h

At noon, ship A is 50 km west of ship B. Ship A is sailing south
at 20 km/h and ship B is sailing north at 10 km/h. How fast is the
distance between the ships changing at 4:00 PM? (Round your answer
to one decimal place.)

3. (5pts) At noon, ship A is 120km west of ship B. Ship A is
sailing north at 35km/h and Ship B is sailing south at 25km/h. How
fast is the distance between the ships changing at 4:00pm

At noo. Ship A is 50km west of Ship B. Ship A is
sailing at 20 km/h and Ship B is sailing north at 10 km/h. How fast
is the distance between the ships changing at 4:00 Pm. Round to one
decimal place.

Gravel is being dumped from a conveyor belt at a rate of 25
ft3/min, and its coarseness is such that it forms a pile
in the shape of a cone whose base diameter and height are always
equal. How fast is the height of the pile increasing when the pile
is 12 ft high? (Round your answer to two decimal places.)

please don't answer unless you can do all parts, circle answer
and show work please
part 1)
A 13 foot ladder is leaning against a wall. If the top slips
down the wall at a rate of 3 ft/s, how fast will the foot be moving
away from the wall when the top is 9 feet above the ground? The
foot will be moving at ft/s.
