The data below shows the temperature of the water in a swimming pool over a two week period. Week 1 DayTemperature (°F) Monday58 Tuesday48 Wednesday49 Thursday61 Friday58 Saturday51 Sunday39 Week 2 DayTemperature (°F) Monday68 Tuesday74 Wednesday73 Thursday75 Friday70 Saturday67 Sunday63 How many degrees greater is the mean temperature in week 2 than in week 1? a0°

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

answer: 100

step-by-step explanation:

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
