If c is a set with c elements how many elements are in the power set of c

There would be 2 raised to c elements in the power set. Elements of the power set are formed by making a binary decision on each element of the input set: include or do not include. Since there are two choices for each element of the input set, and there are c elements in the input set, there are 2^c possible arrangements of these input elements.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
