I'm having problems with a differential equation word problem. A home buyer can afford to spend no more than $800/month on mortgage payments. suppose that the interest rate is 9% and that the term of the mortgage is 20 years. Assume that interest is compounded continuously and that payments are also made continuously. (a) determine the max amount that this buyer can afford to borrow (b) determine the total interest paid during the term of the mortgage.

Anyone? 15m is what percent of 60m; 3m; 30m; 1.5 km?

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?

What is 100,000 times 1/100,000, using the standard method of multiplication? write the answer as 10 to a power.
