Afuel is purified by passing it through a clay pipe. each foot of the clay pipe removes a fixed percentage of impurities in the fuel. let f(x) represent the amount of pollutants, in tons, left in the fuel after it had passed through x feet of the clay pipe: f(x) = 10(0.8)x what does the number 0.8 represent? every foot of the pipe keeps 80% of the pollutant. every foot of the pipe removes 80% of the pollutant. the original amount of pollutant present in the fuel was 80 tons. the original amount of pollutant present in the fuel was 20 tons.

The equation calculates the amount of pollutants left in the fuel, so the 0.8 in the equation would represent that every foot of the pipe keeps 80% of the pollutant.

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
