  • how many different ways

    A spymaster has a network of 11 operatives whom he pays out of a slush fund containing $24000. For accounting reasons, his service requires him to use up his entirefund and to pay his operatives in integer multiples of $1000.(a) How many different ways can he pay his operatives?(b) Since an unpaid operative is unreliable, the spymaster decides that every operative will get at least $1000. With this rule, how many different ways can he pay hisoperatives?How do I approach this problem?

  • Antiderivatives

    The question is: Since raindrops grow as they fall, their surfacearea increases and therefore the resistance to their fallingincreases. A raindrop has an initialdownward velocity of 10m/s andits downward acceleration isa=9-0.9tif0if t > 10If the raindrop is initially 500m above the ground, how longdoes it take to fall?
