You and a friend are riding your bikes to a restaurant that you think is east; your friend thinks the restaurant is north. You both leave from the same point, with you riding at 16 mph east and your friend riding 12 mph north. After you traveled 4 mi, at what rate is the distance between you changing? 5(H’(t))=3(12)+4(16) 5H’(t) = 36+64 5H’(t)=100 H’(t)=100/5 H’(t)=20 The distance changes at the rate of 20mph after 4 miles 0. Consider a right cone that is leaking water. The dimensions of the conical tank are a height of 16 ft and a radius of 5 ft. How fast does the depth of the water change when the water is 10 ft high if the cone leaks water at a rate of 10 ft3/min?

A tank is shaped like an upside-down square pyramid, with base of 4 m by 4 m and a height of 12 m (see the following figure). How fast does the height increase when the water is 2 m deep if water is being pumped in at a rate of 2/3 m3/sec? a=1/3h Volume=1/27h^3 dV/dt=(h^2/9)(dh/dt) dh/dt=6h^2 = 6(2)^2 = 24m/sec The rate of height of pyramid at which rising in it is 24m/min when the height is 2m 0.

Que 1.
Answer:
Now,
Que 2. You and a friend are riding your bikes to a restaurant that you think is east; your friend
thinks the restaurant is north. You both leave from the same point, with you riding at 16 mph east and your friend riding 12 mph north. After you travelled 4 mi, at what rate is the distance between you changing?
Answer:
    Let distance covered by me and my friend in time t is given by
    Let distance covered by me and my friend in time t is given by
Now distance D between me and my friend is given by
Therefore,
This is the rate of distance between me and my friend, which is constant at any time.
Que 3. Consider a right cone that is leaking water. The dimensions of the conical tank are a height of 16 ft and a radius of 5 ft. How fast does the depth of the water change when the water is 10 ft high if the cone leaks water at a rate of 10 ft3/min?
Answer:
    Let any time , water height is and radius of water at that height is .
Then,
Then volume is
Given, at
Therefore,
Que 4. A tank is shaped like an upside-down square pyramid, with base of 4 m by 4 m and a height of 12 m (see the following figure). How fast does the height increase when the water is 2 m deep if water is being pumped...
