When “superballs” sprang upon the scene in the 1960s, kids across the United States were amazed that these hard rubber
balls could bounce to 90% of the height from which they were
dropped. If a superball is dropped from a height of 2 m, how
far does it travel until it stops bouncing? [Hint: The ball goes
down to the first bounce, then up and down thereafter.]

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
