To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
Last |
|
First |
|
Inside |
|
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.
The dimensions of this trapezoid are a = 5, b = 7, c = 8, d = 9, and h = 4. What is the area?
| 10 | |
| 32 | |
| 16\(\frac{1}{2}\) | |
| 19\(\frac{1}{2}\) |
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(7 + 9)(4)
a = ½(16)(4)
a = ½(64) = \( \frac{64}{2} \)
a = 32
Solve for z:
-3z - 9 > -5 - z
| z > -\(\frac{7}{9}\) | |
| z > -2 | |
| z > 1\(\frac{3}{4}\) | |
| z > 8 |
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 > sign and the answer on the other.
-3z - 9 > -5 - z
-3z > -5 - z + 9
-3z + z > -5 + 9
-2z > 4
z > \( \frac{4}{-2} \)
z > -2
On this circle, line segment CD is the:
radius |
|
circumference |
|
diameter |
|
chord |
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 is not required to define the slope-intercept equation for a line?
\({\Delta y \over \Delta x}\) |
|
x-intercept |
|
slope |
|
y-intercept |
A line on the coordinate grid can be defined by a slope-intercept equation: y = mx + b. For a given value of x, the value of y can be determined given the slope (m) and y-intercept (b) of the line. The slope of a line is change in y over change in x, \({\Delta y \over \Delta x}\), and the y-intercept is the y-coordinate where the line crosses the vertical y-axis.
