Convert a-5 to remove the negative exponent.
| \( \frac{-1}{-5a} \) | |
| \( \frac{1}{a^5} \) | |
| \( \frac{5}{a} \) | |
| \( \frac{1}{a^{-5}} \) |
To convert a negative exponent to a positive exponent, calculate the positive exponent then take the reciprocal.
What is the next number in this sequence: 1, 6, 11, 16, 21, __________ ?
| 22 | |
| 34 | |
| 29 | |
| 26 |
The equation for this sequence is:
an = an-1 + 5
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 5
a6 = 21 + 5
a6 = 26
Charlie loaned Damon $400 at an annual interest rate of 1%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $72 | |
| $30 | |
| $9 | |
| $4 |
The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:
interest = annual interest rate x loan amount
i = (\( \frac{6}{100} \)) x $400
i = 0.01 x $400
i = $4

|
-1 |
An integer is any whole number, including zero. An integer can be either positive or negative. Examples include -77, -1, 0, 55, 119.
What is \( \frac{4}{6} \) x \( \frac{3}{6} \)?
| \(\frac{1}{3}\) | |
| \(\frac{2}{21}\) | |
| \(\frac{1}{6}\) | |
| \(\frac{1}{10}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{4}{6} \) x \( \frac{3}{6} \) = \( \frac{4 x 3}{6 x 6} \) = \( \frac{12}{36} \) = \(\frac{1}{3}\)
