Which of the following expressions contains exactly two terms?
polynomial |
|
monomial |
|
quadratic |
|
binomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
The dimensions of this cylinder are height (h) = 8 and radius (r) = 2. What is the volume?
| 384π | |
| 32π | |
| 81π | |
| 9π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(22 x 8)
v = 32π
Solve for b:
2b + 2 = \( \frac{b}{7} \)
| -1\(\frac{2}{3}\) | |
| -1\(\frac{1}{14}\) | |
| 1\(\frac{1}{9}\) | |
| -1\(\frac{1}{13}\) |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
2b + 2 = \( \frac{b}{7} \)
7 x (2b + 2) = b
(7 x 2b) + (7 x 2) = b
14b + 14 = b
14b + 14 - b = 0
14b - b = -14
13b = -14
b = \( \frac{-14}{13} \)
b = -1\(\frac{1}{13}\)
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
Inside |
|
First |
|
Odd |
|
Last |
To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.
Solve -2b - 9b = 4b - 8z - 3 for b in terms of z.
| -\(\frac{1}{9}\)z + \(\frac{5}{9}\) | |
| -\(\frac{1}{8}\)z - \(\frac{3}{16}\) | |
| 5\(\frac{2}{3}\)z - 2 | |
| -\(\frac{1}{6}\)z + \(\frac{1}{2}\) |
To solve this equation, isolate the variable for which you are solving (b) on one side of the equation and put everything else on the other side.
-2b - 9z = 4b - 8z - 3
-2b = 4b - 8z - 3 + 9z
-2b - 4b = -8z - 3 + 9z
-6b = z - 3
b = \( \frac{z - 3}{-6} \)
b = \( \frac{z}{-6} \) + \( \frac{-3}{-6} \)
b = -\(\frac{1}{6}\)z + \(\frac{1}{2}\)
