Absolute value
The distance from zero...distance can never be negative
Acute Angle
An angle with a measure less than 90 degrees
radius
Distance in a circle from the center to the outside of the circle
diameter
distance across a circle
coefficient
the number before a variable (assume one if a coefficent isn't written)
Alike terms
Terms that have the same variable and exponent
combining alike terms
add the coefficient keep the variable
complementary angles
two or more angles with measures that have the sum of 90 degrees
supplementary angles
two or more angles with measures the sum of 180 degrees.
inequality on a number line
less than left ray
more than right ray
equal sign closed circle
no equal sign open circle
intervals
The amount each "notch" on your x or y axis is worth (intervals must be consistant...going up by the same amount)
congruent
exact sme shape and size (same measure)
similar
Same shape different size
coordinate grid
a graph with x and y axis'
cube
a solid figure with six congruent sides.
Think of a dice
A square prism
Cylinder
Like a prism but with a circular base
height of a prism
the distance between the two bases
height of a triangle
Drop a line from the top of the triangle straight down to the bottom...(forms the right angle)
difference
subtract
dilation
a change in size proportionally (increase or decrese) in all dimensions .
discrete data
NO lines, a set of points not connected...in word problems there can be no half portions, they points represent items (tickets, magazines...etc.)
Continuous data
data over time or with a liquid or distance...something that changes constantly.
distributive property
Multiply the number outside the ( ) by each term inside the ( ).
Domain
Set of x values
Input values
Range
Set of y values
estimate
you must estimate...do not give them the exact answer!!
Explain
Write down a sentence telling how and why you did something.
Constant
A number without a variable
rational number
any fraction, terminating or repeating decimal, all integers and whole numbers, &
perfect squares.
Irrational numbers
Any number with Pi or a non perfect square root, non terminating non repeating decimals.
Integers
positive and negative whole numbers
whole numbers
0,1,2,3....
natural numbers
1,2,3.... (just not the 0)
Expression
no equal sign
equation
has an equal sign
scientific notation
a number greater than 1 but less than 10 multiplied by 10 with an exponent that represents how you moved your decimal
negative exponent with scientific notation
this starts off as a small, small decimal (always a number less than 1)
positive exponent with scientific notation
this is a large number usually greater than 100 (always greater than 10)
fraction
a fraction means division
multiplying fractions
multiply across the numberator and multiply across the denominator
simplifying fractions
arrow one multiply across the numerator, arrow two divide across the denominator.
hypotenuse
the longest side in a right triangle always directly across from the right angle.
histogram
like a bar graph but without the spaces between them.
ratio
make a fraction
unit rate
how much for one? Divide
intersection
the point where two lines meet
market equilibrium
when your expenses and profit even out (the point where the two lines intersect...)
Isosceles triangle
two congruent sides (same measure), two congruent base angles.
lateral area
the surface area of all the sides (do not include the top or bottom)
box and whisker graph
seperates data into quartiles (25% portions)
easy to find hi and low and median
scatter plot
Used when there are multiple y value possibilities for one x value.
Maximum
the greatest or highest value
minimum
the lowest value
mean
average
outlier
significantly different that the other data.
trend
increasing (going up at the graph moves right)
decreasing (down as the graph moves right)
No trent (all over the place)
In a right triangle, The sum of the squares of the lengths of the legs will be equal to the square of the third side of the triangle.
median
middle number
obtuse angle
angle with a measure larger than 90 degrees
right angle
an angle measure of 90 degrees
coorresponding angles
two congruent angles in the same place on two different parallel lines
vertical angles
congruent angles that are directly across from each other
adjactent angles
angles that share a vertex and a side
vertex
the common endpoint for two rays that form an angle
Origin
Where the x and y axis meet (0,0)
Percent
write a proportion using %/100, partial/total.
odds
are/are not
probability
are/total
Theoretical Probability
used to find the probability of an event when all outcomes are equally likely
Determined by actually trying an experiment and recording the outcomes
polygon
a closed figure with straight lines (hexagon, square, etc...)
perpendicular
two lines that meet to form four right angles
product
multiply
radical
"root" for your purposes...square root
pyramid
three dimensional figure that comes to a point opposite of the base. Divide by 3 at the end for volume...
Range
difference between the high and low values
This word has two different uses...
equation for rate of change
Y- Intercept
point where the line crosses y-axis
x-intercept
the x-coordinate of a point where a graph crosses the x-axis
slope-intercept form
y = mx + b
Slope =
rise/run = change in "y"/change in "x"
reciprocal
"flip" your fraction
when do you flip an inequality?
When you multiply or divide by a negative number
reflection
"flip"
systems of equations
Solve using:
Elimination
Substitution
Graphing
Answer will always be in coordinate form (where the two lines meet.)
Interior angles of a polygon
180(n-2)
n stands for the number of sides
one interior angles measure inside a regular polygon
180(n-2)/n
n is the number of sides
straight angle
an angle measure of 180 degrees
sum
add
degree
the highest exponent
standard form
either:
Ax + By = C (graphing)
or
highest exponent to lowest
variable
a letter representing an unknown number
metric system
anything with meter, liter or gram
customary system
anything not liter, meter or gram
inverse variation
As the x values increase the y values decrease.
direct variation
Any two fractions proportional...if you cross multiply two sets you will get the same number.
probability
written as a fraction in reduced form unless told otherwise
ratio
write a fraction in simplest form
fraction
divide
unit rate
how much for one? Divide
Equation
Must have an equal sign
Expression
No equal sign allowed
Contrast
How are they different
Compare
How are they the same?
Origin
Where the x and y axis meet (0,0)
