Any number that you can completely write down on paper using digits ... and a fraction bar or decimal point if necessary ... is a rational number. If you add it to 0.5, then the sum is another rational number.
Hello! For these kinds of problems, the formula for finding the principal is I / rt. That means, divide the simple interest by the rate and time (rate should be in decimal form). In order to find simple interest, just do prt, which means multiply the principal (initial amount) by the rate (simple interest rate, in decimal form) by the amount of time (could be in months or years). With that being said, if you solve it correctly, here are your answers:
Principal: $14,181
Interest rate: 10%
Time: 4 years
Simple Interest: $5,672.40
Principal: $83,079
Interest rate: 9%
Time: 2 years
Simple Interest: $14,954.22
Principal: $659,379.96
Interest rate: 11.7%
Time: 28 months
Simple Interest: $179,753.57
Principal: $18,936
Interest Rate: 2.41%
Time: 3 Months
Simple Interest: $114.09
Note: If the time is in months, be sure to convert it into a decimal and multiply. If a decimal repeats, just convert it to the nearest hundredth.
First one is -6 and the second one is -3
Using the classification for even and odd functions, it is found that the function is even, because f(-x) = f(x).
<h3>How we verify if the function is even, odd, or neither?</h3>
- If for all values of x, f(x) = f(-x), the function is even.
- If for all values of x, f(-x) = -f(x), the function is odd.
- If neither of these statements are true, the function is neither even nor odd.
Graphing the function 
, for every value of x, f(x) = -f(x), that is, the function is symmetric over the y-axis, hence it is even.
