Describe how the graph of each function is related to a basic trigonometric graph. then, graph two periods.

1. y=0.5 cos(3x) description:

2. y=-2 sin(2πx/3) description:

The answer is y= -2

Step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk
