The Stratosphere Tower is Las Vega dominate the city's landscape by rising 1,149 feet above the desert floor. The restaurant at the top of the tower turns slowly and completes a full revolution in one hour. How many radians will the restaurant have rotated in 52 minutes?

There is a pretty standard way of doing this sort of problem. Keep it in mind when you encounter this sort of expression. Write sqrt(49x^2+x)-7x=[sqrt(49x^2+x)-7x][sq... =[49x^2+x-49x^2]/[sqrt(49x^2+x)+7x] =x/[sqrt(49x^2+x)+7x] =1/[sqrt(49+1/x)+7]-> 1/14 as x->+infinity...

When x gets very large, the -x inside the square root is insignificant in comparison to the 4x^6 so can effectively be ignored. The same thing about the 3 on the bottom in comparison to the x^3. The effectively leaves sqrt(4x^6)/x^3 = 2 It is usually a good idea to check with ...

A ball is dropped from a height of 36 feet. The quadratic equation d=1/2 gt^2 is used to calculate the distance (d) the ball has fallen after t seconds. The constant g is the acceleration of gravity, 9.8m/s^2. How long does it take the ball to hit the ground? A ball in problem...

haha me too ! thanks for the answer !!

Combustion reactions involve reacting a substance with oxygen. When compounds containing carbon and hydrogen are combusted, carbon dioxide and water are the products. Using the enthalpies of combustion for C4H4 (-2341 kJ/mol), C4H8 (-2766 kJ/mol) and H2 (-286 kJ/mol), ...
