What do we call the lines connecting the foci in an ellipse?
-
Minor Axis
-
Ellipsoid
-
Vertex
-
Major Axis
Correct Answer
A. Major AxisExplanation
The lines connecting the foci in an ellipse are called the major axis. The major axis is the longest diameter of the ellipse and passes through the two foci. It divides the ellipse into two equal halves, known as the major semiaxes. The major axis is an important characteristic of an ellipse and helps determine its shape and orientation.Rate this question:

What kinds of numbers do not terminate and do not repeat?
-
Rational Numbers
-
Irrationals Numbers
-
Integers
-
Whole Numbers
Correct Answer
A. Irrationals NumbersExplanation
Irrational numbers are numbers that cannot be expressed as a fraction or ratio of two integers. They do not terminate (end) or repeat (have a recurring pattern) when expressed as decimals. Examples of irrational numbers include the square root of 2 (√2), pi (π), and e.Rate this question:

What is the solution to: x + y = 6 and x - y = 2?
-
(3,1)
-
(1,3)
-
(2, 4)
-
(4, 2)
Correct Answer
A. (4, 2)Explanation
The solution to the given system of equations is (4, 2). This can be found by solving the equations simultaneously. By adding the two equations, we get 2x = 8, which means x = 4. Substituting this value of x into either of the original equations, we can solve for y. Substituting x = 4 into the first equation, we get 4 + y = 6, which means y = 2. Therefore, the solution is (4, 2).Rate this question:

What is x, if the absolute value of x is 3?
-
0
-
3
-
3 & -3
-
-3
Correct Answer
A. 3 & -3Explanation
The absolute value of a number is the distance of that number from zero on the number line. In this case, the absolute value of x is given as 3. This means that x can be either 3 or -3, as both numbers are 3 units away from zero in opposite directions. Therefore, the correct answer is 3 & -3.Rate this question:

If two equations intersect at one point, what do we call that system?
-
Consistent
-
Coincident
-
Dependent
-
Inconsistent
Correct Answer
A. ConsistentExplanation
When two equations intersect at one point, we call that system consistent. This means that there is a unique solution to the system of equations. If the system was inconsistent, it would mean that the equations do not intersect at any point and there is no solution. Dependent systems have infinitely many solutions and coincident systems refer to equations that are essentially the same.Rate this question:

If two graphed equations produce the same line, what do we call them?
-
Coincident
-
Inconsistent
-
Independent
-
Consistent
Correct Answer
A. CoincidentExplanation
When two graphed equations produce the same line, we call them coincident. This means that the two equations have the same slope and y-intercept, resulting in identical lines on the graph. In other words, the equations represent the exact same relationship between the variables and have an infinite number of solutions in common.Rate this question:

What kind of line is y = 3?
-
Curved
-
Horizontal
-
Vertical
-
Slanted
Correct Answer
A. HorizontalExplanation
The equation y = 3 represents a horizontal line because the value of y remains constant at 3 regardless of the value of x. In a horizontal line, the slope is always zero, indicating that the line does not rise or fall. Therefore, the line y = 3 is a horizontal line that is parallel to the x-axis.Rate this question:

What is tan 18 degrees?
-
-3249
-
-0.3249
-
3249
-
0.3249
Correct Answer
A. 0.3249Explanation
The answer to the question "What is tan 18 degrees?" is 0.3249. This value represents the tangent of the angle 18 degrees. The tangent function calculates the ratio of the length of the side opposite the angle to the length of the adjacent side in a right triangle. In this case, when the angle is 18 degrees, the tangent is positive and equal to 0.3249.Rate this question:

What values of x will make x^2 = 16 a true statement?
-
0
-
4
-
-4
-
4 & -4
Correct Answer
A. 4 & -4Explanation
The values of x that will make the equation x^2 = 16 true are 4 and -4. This is because when we square 4, we get 16, and when we square -4, we also get 16. Therefore, both 4 and -4 satisfy the equation x^2 = 16.Rate this question:

To complete the square for x^2 - 8x = 0, what do we add to both sides?
-
16
-
-16
-
4
-
-4
Correct Answer
A. 16Explanation
To complete the square for the equation x^2 - 8x = 0, we need to add half of the coefficient of x, squared, to both sides of the equation. In this case, the coefficient of x is -8, so half of it is -4. Squaring -4 gives us 16. Therefore, to complete the square, we add 16 to both sides of the equation.Rate this question:

What equation can be written given a slope and a y-intercept?
-
Vertical
-
Point-Slope Form
-
Horizontal
-
Slope-Intercept Form
Correct Answer
A. Slope-Intercept FormExplanation
The slope-intercept form of an equation is y = mx + b, where m represents the slope and b represents the y-intercept. Therefore, the equation that can be written given a slope and a y-intercept is the slope-intercept form.Rate this question:
