Answer:
Domain = {0.-6}
Range = {-2, 4}
Notes We find coordinates and radius and state
Then we show formula (x -x1)^2 + (y +y1) = r ^2 and show
(x -3 )^2 + (y − 1)^2 = 9 = R^2 THE RADIUS^2
then ;
Domain formula = x - r and x + r
Range formula = y - r and y + r
Step-by-step explanation:
The graph is a circle so all the points are enclosed in it
The domain is the values for x so you subtract the radius from the centre coordinate and you add the radius to it The range is the values for y so you do the same to the y coordinate If you use
(x- x1) ^2 + (y - y1) ^2
(x -3 )^2 + (y − 1)^2 = 9
However this changes if centre coordinate shows negatives
we change negative x or y to + positive in the formula in bold.
Centre coordinate = (3.,1) radius is 3 SO = MUST BE THE RADIUS ^2
= (x - 3)^2 + (y - 1)^2 = 3^2 = 9
Domain formula = x - r and x + r
Domain = 3 - 3 = 0
and - 3 + 3 = -6
Domain = {0.-6}
Range formula = y - r and y + r
Range = 1 - 3 = -2
and 1 +3 = 4
Range = {-2, 4}
For a cyclic quadrilateral
The opposite angles are supplementary (meaning they sum up to 180 °)
I.e (x +20) ° + 3x ° =180 °
20 + 4x = 180
4x=180 - 20
4x = 160
Divide through by 4
x = 40 °
Angle at point A
(2x + 38) = (2(40) + 38) = 118 °
Angle at point B
3x = 3(40) = 120 °
Angle at point D
x + 20 = 40 + 20 = 60 °
Angle at point C
The total angle in a quadrilateral is 360 °
I.e 118 + 120 + 298 +
Well first you should know that 4/10 is simplified to 2/5 so that part is correct
But to know of the rest is correct , add the Fractions
so the common denominator will be 8 so 1/2 will become 4/8 + 3/8 = 7/8 but 7/8 does not equal 4/10
Answer: 6
Step-by-step explanation:
8x6=48 you would have 6 inches left over
Answer:
(5,9)
(-19, - 15)
(5, - 15)
(-19, 9)
Step-by-step explanation:
Given that :
Coordinate of point A = - 7, - 3
Number of points between point A and B = 12
Possible coordinate of point B
Possible coordinates of point B:
(-7, - 3) + 12 = (5, 9)
(-7, - 3) - 12 = (-19, - 15)
(-7, - 3) = (-7 +12, -3 - 12) = (5, - 15)
(-7, - 3) = (-7 - 12, - 3 + 12) = (-19, 9)
Hence possible coordinates of be are :
(5,9)
(-19, - 15)
(5, - 15)
(-19, 9)
