If the length of AB equals the length of BD, point B __________ this line segment.
trisects |
|
bisects |
|
midpoints |
|
intersects |
A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
Inside |
|
Last |
|
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.
Simplify 7a x 6b.
| 42ab | |
| 42a2b2 | |
| 42\( \frac{b}{a} \) | |
| 42\( \frac{a}{b} \) |
To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.
7a x 6b = (7 x 6) (a x b) = 42ab
The dimensions of this trapezoid are a = 6, b = 5, c = 9, d = 2, and h = 5. What is the area?
| 17\(\frac{1}{2}\) | |
| 21 | |
| 40 | |
| 9 |
The area of a trapezoid is one-half the sum of the lengths of the parallel sides multiplied by the height:
a = ½(b + d)(h)
a = ½(5 + 2)(5)
a = ½(7)(5)
a = ½(35) = \( \frac{35}{2} \)
a = 17\(\frac{1}{2}\)
The endpoints of this line segment are at (-2, 3) and (2, -7). What is the slope of this line?
| -2 | |
| \(\frac{1}{2}\) | |
| -2\(\frac{1}{2}\) | |
| -1 |
The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, 3) and (2, -7) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(-7.0) - (3.0)}{(2) - (-2)} \) = \( \frac{-10}{4} \)
