Answer 1

for question 1), it's just 0,1. if it were negative, 5^-2 is 1/25. question 2 is correct. question 3 is also correct. question 4 is wrong, the answer is 1665.31 because to find an answer to a compounded quarterly question, you divide the interest (3.5%, or 0.035) by 4, getting 0.00875. then the equation is y=1500(1+0.00875)^12 (because, also since its quarterly, you multiply 4 by the amount of time the money is in there, so 3 years.) question 5 is 1657.24, with the same method as question 4. the equation is y=1500(1+0.00625)^16
