If h moves the graph left or right,

(moves left)

(moves right)
If a vertical stretch by a factor of |h|, then

If h moves the graph up or down,

(moves up)

(moves down)

and h = 1
0.72 repeating is the sum of a geometric series with first term 0.72 and common factor 1/100. The sum is given by:
(first term) 0.72 0.72 72
--------------------------- = --------------- = ------------ = ------------
1 - common factor 1 - 1/100 99/100 99
This 72/99 can be reduced to 8/11.
0.72 repeating can be rewritten as the fraction 8/11.
Answer + step-by-step explanation:
125
c = a2 + b2 = 75^2 + 100^ 2=125
