Answer:
4:5 or 0.8
Step-by-step explanation:
if the correspond sides are 24 (smaller figure) and 30 (larger figure), then the requred scale factor is:
24:30=4:5 (or 0,8).
Y = cos x begins at (0,1), descends to (pi/2,0), descends to (pi,-1), ascends to (3pi/2,0), and then ascends to (2pi,1). This covers only one full period.
The graph of y = 2cost x is the same, except that the amplitudes (y-values) are 2x as great as before:
(0,2), (pi/2, 0), and so on.
