OAE 055 Math Questions and Answers
Slope Correct Ans-the steepness of a line on a graph, rise over run
Standard form Correct Ans-Ax + By = C
Slope intercept form Correct Ans-y=mx+b
where m is the slope and b is the y-intercept of the line
point slope form Correct Ans-y-y₁ = m(x-x₁)
where m is the slope and (x₁,y₁) is a point on the line
Two-point form Correct Ans-((y-y1)/(x-x1)) = ((y2-y1)/(x2-x1)), where (x1, y1) and (x2, y2)
are two points on the given line
midpoint formula Correct Ans-(x₁+x₂)/2, (y₁+y₂)/2
Distance Formula Correct Ans-d = √[( x₂ - x₁)² + (y₂ - y₁)²]
Multiplying Polynomials/Binomials Correct Ans-FOIL (first, outer, inner, last)
(Ax + By)(Cx + Dy)
, Quadratic Formula Correct Ans-x = -b ± √(b² - 4ac)/2a
standard form Correct Ans-Ax + By = C
Domain Correct Ans-The set of input values of a function.
Range Correct Ans-The set of all possible output values of a function
scientific notation Correct Ans-A method of writing or displaying numbers in terms of a
decimal number between 1 and 10 multiplied by a power of 10
(230,400,000 = 2.304 x 10^8)
