Find the period of the graph shown below.

π/2

Step-by-step explanation:

Find the period of the graph shown below.

Total time to complete one oscillation is called the period.

The total number of oscillations in the graph is 7 oscillations:

Hence;

7 oscillations = 3π + π/2 = 7π/2

To get the period, we want to know thw angle it takes to complete just one oscillation that is;

1 oscillation = x

Divide both equations:

7/1 = (7π/2)/x

7x = 7π/2

14x = 7π

x = 7π/14

x = π/2

Hence the period of the wave is π/2

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
