This is the formula for compounded interest. P is the principal investment, r is the rate (6%=0.06) n is the number of times compounded per year (n=12 is monthly, n=2 is twice per year) T is the number of years past And A is the amount of money after t years with a rate r compounded n times per year staring at P amount Final answer: n is the number of times per year the interest is compounded. Hope I helped, and sorry it took this long for you to get an answer.
The mapping rule for 90 degrees counterclockwise would be (-y,x). So if you had (x,y) it would transfer to (-y,x). Yours is wrong it should be (4,-3). Remember -(-4) is 4 and -3 stays as -3.
