Workers on a factory floor are painting one side of circular discs that will be placed on an assembly line. For every gallon of paint, a worker can paint an area that measures 1,256 square feet. If each disc has a radius of 2 feet, how many discs can they paint with one gallon of paint? Use 3.14 for π.

=====================================

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer

the answer is:

mean: 6

mad: 2.14

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely
