Ray
What is a line with one endpoint that extends forever in the other direction?
100
Quadratic function
What is a function where a variable squared is the highest degree polynomial?
100
Pi is defined as the ratio of these two quantities
What is circumference and diameter?
100
Why does area use units squared while volume uses units cubed?
Area is 2-D while volume is 3-D
100
The value of the expression (2+1) * 3^2 - 1
What is 26?
200
Congruent Shapes
What are two shapes that have equal angle and line segment measurements?
200
The period of a sinusoid
What is the time it takes for the wave to complete a full cycle?
200
e is calculated by this exponential expression.
What is (1 + 1/n)^n as n approaches infinity?
200
Why do parallel lines have the same slope?
Since they are going the same direction, the ratio of rise/run will be equal.
200
2 raised to the eighth power
What is 256?
300
Translation
What is "shifting" a geometric shape on the coordinate plan by adding/subtracting to/from the coordinates?
300
Secant, calculated as a ratio of the side lengths of a right triangle
What is hypotenuse/adjacent?
300
f in function notion, f(x), stand for this in the function.
What is a function name?
300
Why do negative numbers in a square root have no real value?
Because negative * negative is positive, and positive * positive = positive; there are no real numbers multiplied together that make a negative number
300
The value of log base 3 of 81
What is 4?
400
Transitive Property
What is: if a = b and b =c, then a = c?
400
Vertex
What is the point at which a parabola peaks?
400
A linear equation in standard form contains the variable "A", which is used in this way.
What is the constant multiplied by x?
400
Why is tangent equal to the ratio of sine/cosine?
Because sine = opp/hyp and cosine =adj/hyp, sin/cos = (opp/hyp)/(adj/hyp), the hyp's cancel, leaving opp/adj (tangent)
400
The value of sin (225 degrees).
What is -1/sqrt(2) or -sqrt(2)/2?
500
Skew Lines
What are lines on separate planes that are not parallel but never intersect?
500
Imaginary number
What is a number that contains i, the square root of -1?
500
In a translated function, the variable "h" stands for a constant that does this.
What is shifting the graph of a function horizontally?
500
Why is the circumcenter of a right triangle on the hypotenuse?
When an inscribed angle in a circle meets the edges of a circle, the inscribed angle is half the arc. An angle of 90 degrees produces an arc of 180 degrees (a semicircle), which makes the hypotenuse a diameter of the circle.
500
The solution to the equations (x = 2y - 1) and (2x + 2y = 10)
What is (3, 2)?
