6⁵x6⁴
6⁹
circle area and circumference
a=πr² c=2πr
order of operations
PEMDAS
real numbers
everything but imaginary numbers
y³/y⁴
y³-y⁴=y-¹→→→→1/y
(4y)²
4²y²
perpendicular angle
90 degree
median
in the middle
(4²)³
4²x³=4⁶
x²+2xy+y²
(x+y)(x+y) or (x+y)²
vertical axis (height)
2b
inequalities multiply or diving by neg number
flip sign
similar triangles vs congruent triangles
similar - same shape, different size, = angles, sides are proportional congruent - same shape, same size
rational numbers
any whole number→no fractions or decimals
Vertical <
always equal each other
open circle VS closed circle on number line
open----not included closed---pt included in line
Distance Formula
d = √[( x₂ - x₁)² + (y₂ - y₁)²] OR extend lines on triangle then use phythag.
the 30-60-90
√3/16
√3/√16 = √3/4
slope formula
m=(y₂- y₁) / (x₂- x₁)
anything to the power of 0
is 1
8²/³
³√8²
circle degree
360
Equation for Horizontal Ellipse
(x-h)²/a² + (y-k)²/b² = 1
multiplying/dividing fraction
across for multiplying flip recip for dividing
Factoring: 2√5 + 4√125 =
2√5 + 4(√25)(√5)= 2(√5)+ 4⊗5 (√5)=22(√5)
x²-y²
(x + y) (x - y)
supplementary <
adds up to 180
subtracting or adding fraction
same denom and then add/subtract across
absolute value
distance between # and 0 on the number line→→→|6|=6 AND |-6|=6 |3x+1|=1 3x+1=1 AND 3x+2=-1
x²-2xy+y²
(x-y)²
mode
numbers that shows up the most
isosceles rt triangle
line degree
180
Average
total↓÷/÷↑# of things*average
(1/2)²
1/4
5√×+20√×
25√X
irrational numbers
nothing is a fraction, goes on forever and doesn't repeat
equation to find the radius of a circle
r^2= (x-h)^2 + (y-k)^2
√x⊗√y
√xy OR 3√5 ⊗ 6√2= 18√10
prime numbers
can be divided equally by 2 and only 2 distinct numbers. ( So 1&#= 1&11)
logₙy=Z
n^z=y
integers
everything, except decimals and neg fractions 0 is a even integer
trapezoid area formula
1/2(b+b)h
x³/²
=1÷x³/₂=1/³√x²
ratios: If the ratio of 2x to 5y is 1/20 what is the x to y ratio
(5/2)2x/5y= 1/20 (5/2)==5/40
midpoint formula
(x1+x2/2, y1+y2/2)
horizontal axis (width) ellipse
2a
combo problems as you to figure out the possibly of combos
basically multiply by #s together 4/G x 3/G x 2/G x 1/G
