I dont know how to do this problem because the answers i plugged into it was wrong. someone please help me and show me how to do it.
what is the minimum power (P) in joules per second (j/s) and in horse power (hp) of the motor which lifts the silver bullet and riders to the top of the first incline? the distance of the incline (d) is 150m and it takes 45 seconds for the silver bullet to go tot he top of the incline. (assume the silver bullet has a mass of 10,000 kg and each rider averages 73.0kg and 100 passengers ride at a time.)
***Remember p=work/time=Fd / t =mgd/t, where m = mass, g=10m/s^2, d=total distance of the incline and 1 hp = 746w.***
Answer is P=5.76 x 10^5 W=773hp

The answer to your Binomial Coefficients problem would be these simple, yet easy steps.
The Column of a Matrix is what you're looking for and you need to first realize your objective.
So you have 150m and it takes 45 seconds, no problem. You just have to first use the quadratic formula for that bit which is x=-b + or - the 2 root of b2 - 4ac divided by 2a and you need to plug in your answers there. So you take 150m and replace it in for x and you put 45 into the a sections, only because that's the seconds. Then you solve and you can find what b is equivalent to, and then b is your answer for P. How to find W is more complicated, you have to use the Explicit Formula of a Sequence type of formula and x is your answer for W.
