Answer:

D Antenna #4

Step-by-step explanation:

As per given graph we can write the function

  • the intercept is zero, as x=0, y=0
  • at x=2, y=30  ⇒ 30= 2*15
  • at x=4, y=60 ⇒ 60= 4*15

The slope is 15, so the function is

  • y=15x

And the function for the antenna revolving at twice the rate would be

  • y=30x

Comparing data in given tables we can see it is D Antenna #4

  • x= 22 ⇒ y= 22*30= 660
  • x=24 ⇒ y= 24*30= 720
