Which is an example of periodic motion? • A, completing a long football pass
B. bouncing a basketball
C, hitting a homerun
r
• D. stopping a soccer ball with your foot

I’m pretty sure the answer is B. Periodic motion is when the motion of an object is repeating itself, like back and forth or circling in an orbit and whenever you bounce a ball, you continuously bounce it back and forth.

the formula for the cost is

c = l + p

Total cost is £47

Step-by-step explanation:

Let c represent the cost in £ of a monthly phone contract made up of the fixed line rental l in £ and the price p in £ of the calls made.

The formula for the cost, c would be

c = l + p

if the line rental is £35 and the price of calls made is £12, then, the total cost, c would be

c = 35 + 12 = £47
