Order the following types of angle from least number of degrees to most number of degrees.
acute, obtuse, right |
|
right, acute, obtuse |
|
right, obtuse, acute |
|
acute, right, obtuse |
An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
On this circle, line segment CD is the:
radius |
|
circumference |
|
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 is not required to define the slope-intercept equation for a line?
y-intercept |
|
slope |
|
x-intercept |
|
\({\Delta y \over \Delta x}\) |
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.
Solve for c:
-2c - 2 > -4 - 3c
| c > -\(\frac{7}{8}\) | |
| c > -2 | |
| c > -1\(\frac{2}{5}\) | |
| c > -1\(\frac{1}{2}\) |
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.
-2c - 2 > -4 - 3c
-2c > -4 - 3c + 2
-2c + 3c > -4 + 2
c > -2
On this circle, a line segment connecting point A to point D is called:
