A coordinate grid is composed of which of the following?
x-axis |
|
y-axis |
|
origin |
|
all of these |
The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.
The endpoints of this line segment are at (-2, -7) and (2, 3). What is the slope of this line?
| \(\frac{1}{2}\) | |
| 2 | |
| 2\(\frac{1}{2}\) | |
| 1\(\frac{1}{2}\) |
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, -7) and (2, 3) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(3.0) - (-7.0)}{(2) - (-2)} \) = \( \frac{10}{4} \)If a = c = 5, b = d = 1, and the blue angle = 55°, what is the area of this parallelogram?
| 8 | |
| 45 | |
| 36 | |
| 5 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 5 x 1
a = 5
The dimensions of this cube are height (h) = 8, length (l) = 2, and width (w) = 1. What is the volume?
| 378 | |
| 96 | |
| 16 | |
| 432 |
The volume of a cube is height x length x width:
v = h x l x w
v = 8 x 2 x 1
v = 16
On this circle, line segment AB is the:
chord |
|
circumference |
|
diameter |
|
radius |
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).
