A pelican flying in the air over water drops a crab from a height of 30 feet. Th distance the crab is from the water can be represented in the function h(t)= -16t^2+30, where t is time in seconds. To catch the crab as it falls, a gull flies along a path represented by the function g(t)= -8t^2+15. Can the gull catch the crab before it hits the water? If u do answer plz explain. thx

1) A street light is mounted at the top of a 15 ft pole. A man 6 ft tall walks away from the pole with a speed of 5 ft/s along a straight path. How fast is the tip of his shadow moving when he is 40 ft from the pole.
2) Water is leaking out of an inverted conical tank at a rate of 10,000 cm cubed/minute at the same time that water is being pumped into the tank at a constant rate. The tank has height 6 m and the diameter at the top is 4 m. If the water level is rising at a rate of 20 cm/min when the height of the water is 2 m, find the rate at which water is being pumped into a tank.

I know this is so dumb but I haven't seen this one guy I have a crush on in years and he is coming up here to see me. Anyway he says he is 6 ft even and I'm 5'10 so i wanted to compare are heights. Anyway how many inches are in 6ft. We are supposed to be getting back together because I guess he is moving up here for me. All I have is inch ruler nothing else and I am trying to convert inches to feet so can you help me please. The question again is how many inches are in 6ft?

I have a set of numbers, W_i, where

0
And I know that

sum( 1 / (1+W_i) ) = 1 (summed over all n, sorry but I can't remember LaTeX).


Define P_i with

P_i = W_i/4 .

From the information above, how do I find the boundaries of

sum(1/(1+P_i)) ???

Does it belong somewhere between 2 and 4?
