Which of the following is not required to define the slope-intercept equation for a line?

42% Answer Correctly

	y-intercept
	x-intercept
	\({\Delta y \over \Delta x}\)
	slope

Solution

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.

On this circle, line segment AB is the:

70% Answer Correctly

	diameter
	radius
	circumference
	chord

Solution

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).

If AD = 30 and BD = 21, AB = ?

76% Answer Correctly

	6
	8
	9
	1

Solution

The entire length of this line is represented by AD which is AB + BD:

AD = AB + BD

Solving for AB:

AB = AD - BD
AB = 30 - 21
AB = 9

The dimensions of this cylinder are height (h) = 7 and radius (r) = 5. What is the volume?

62% Answer Correctly

	175π
	45π
	245π
	150π

Solution

The volume of a cylinder is πr²h:

v = πr²h
v = π(5² x 7)
v = 175π

What is the circumference of a circle with a diameter of 19?

71% Answer Correctly

	1π
	2π
	19π
	11π

Solution

The formula for circumference is circle diameter x π:

c = πd
c = 19π
