Interest rates fluctuate with the economy. In the 1980's, the highest CD interest rate was over 16%. By 2017, the highest CD interest rates were approximately 2%.
A. If $1,000 is invested at 16% interest, compounded continuously, for 5 years, what is the ending balance?
Round to the nearest cent.
B. If $1,000 is invested at 2% interest, compounded continuously, for 5 years, what is the ending balance?
Round to the nearest cent.
C. What is the difference between the two ending balances?

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?

The graph shows the decibel measure for sounds depending on how many times as intense they are as the threshold of sound. noise in a quiet room is 500 times as intense as the threshold of sound. what is the decibel measurement for the quiet room? 20 decibels28 decibels200 decibels280 decibels

Find the power set of each of these sets, where a and b are distinct elements. a) {a} b) {a, b} c) {1, 2, 3, 4} show steps
