Martin's running ability is measured by this proportion:
jek_recluse [69]

Answer:

A = 13 B =0 = 1/2   This way x in a graph can be his start running ability (time) each A value applied will divide by 1/2 to make 6.5 and when x = 21 then y can be 7 with the AB equation above as 13 x 1/2 = 6.5. add multiple 0 doesn't occur because we start with x value 21 to show the starting value. Alternately x= 137 and y = 0. Then the graph can go up or down when his running value changes as a negative decrease 137 - b = -? and a positive increase will show increase 137+b = +?.

The graph of the sine curve below is of electromagnetic energy that represents red light:
nordsb [41]
The general form of sine curve is   f(x) = a sin (nx)
Where: a is the amplitude and n = 2π/period

Given the points of the sine curve which is 
(0, 0) and (160, 1) and (320, 0) and (480, -1) and (640, 0)

the maximum value of f(x) = 1 , and the minimum value of f(x) = -1
∴ amplitude = a =1

And the function complates one cycle from 0 to 640
∴ period = 640  ⇒⇒⇒ n = 2π/640 = π/320

∴ f(x) = 1 * sin (π/320)x = sin (π/320)x

∴ The correct answer is option d
<span>d) f(x) = sin pi over 320x</span>
