Dorji adds some sugar cubes that has a volume of 20 cm3 and pours 200 ml of hot water in a mug to the brim. What will be the capacity of mug? A.180 ml
B.220 ml
C.400 ml
D.4000 ml
Pls explain step by step ☺

The sugar cubes do not remove volume but add to it. A is eliminated for 200 mL cannot decrease. If it is only one sugar cube the equation to find the capacity is 200+20=220. This equation could change with new amounts of sugar cubes in which your equation would be 200+20x with x being the number of sugar cubes added.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
