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}
Answer:
There are 16 boxes left in total
Step-by-step explanation:
First we add the amount of boxes at the beginning: 75 + 80 = 155
Then, we add the amount of boxes that were sold: 68 + 71 = 139
Then, we subtract the total amount of boxes sold from the total amount of boxes at the beginning: 155 - 139 = 16
Answer: 30
Step-by-step explanation:
Let the number be y
Add 5 to me
Y+5............equ1
Divide by 7
Y+5/7
Add 12
Y+5/7+12
Subtract 7
(Y+5)/7+(12-7)=10
12-7=5
Substitute
(Y+5)/7+5=10
Find the lowest common multiple
((Y+5)+7(5))/7=10
(Y+5)+35)/7=10
Cross multiply
Y+5+35=70
Y+40=70
Y=70-40
Y=30
The unknown number is 30

Answer:
(a) 2
Step-by-step explanation:
Each inch is 2.54 cm, so 5.08 cm is ...
x / (5.08 cm) = (1 in) / (2.54 cm)
x = (1 in)(5.08/2.54) = (1 in)(2)
x = 2 in
5.08 cm equals 2 inches.
