On this circle, line segment AB is the:
circumference |
|
radius |
|
chord |
|
diameter |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
Which of the following expressions contains exactly two terms?
quadratic |
|
polynomial |
|
binomial |
|
monomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
If side x = 10cm, side y = 12cm, and side z = 10cm what is the perimeter of this triangle?
| 26cm | |
| 32cm | |
| 25cm | |
| 42cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 10cm + 12cm + 10cm = 32cm
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
Last |
|
Inside |
|
First |
|
Odd |
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 -6c + 9c = -3c + 9z + 4 for c in terms of z.
| -\(\frac{1}{4}\)z + \(\frac{5}{8}\) | |
| z - 1\(\frac{1}{3}\) | |
| z + \(\frac{3}{8}\) | |
| \(\frac{3}{14}\)z - \(\frac{1}{7}\) |
To solve this equation, isolate the variable for which you are solving (c) on one side of the equation and put everything else on the other side.
-6c + 9z = -3c + 9z + 4
-6c = -3c + 9z + 4 - 9z
-6c + 3c = 9z + 4 - 9z
-3c = + 4
c = \( \frac{ + 4}{-3} \)
c = \( \frac{}{-3} \) + \( \frac{4}{-3} \)
c = z - 1\(\frac{1}{3}\)
