Answer:
![\sf Period=\dfrac{2}{3} \pi](https://tex.z-dn.net/?f=%5Csf%20Period%3D%5Cdfrac%7B2%7D%7B3%7D%20%5Cpi)
Step-by-step explanation:
The cosine function is <u>periodic</u>, meaning it repeats forever.
<u>Standard form of a cosine function</u>
f(x) = A cos(B(x + C)) + D
where:
- A = amplitude (height from the mid-line to the peak)
- 2π/B = period (horizontal distance between consecutive peaks)
- C = phase shift (horizontal shift - positive is to the left)
- D = vertical shift
Given function:
y = 2 cos (3x - 2π)
Therefore:
<u>Period of given function</u>:
![\sf \implies Period=\dfrac{2 \pi}{B} = \dfrac{2 \pi}{3}](https://tex.z-dn.net/?f=%5Csf%20%5Cimplies%20Period%3D%5Cdfrac%7B2%20%5Cpi%7D%7BB%7D%20%3D%20%5Cdfrac%7B2%20%5Cpi%7D%7B3%7D)

3/8 (14.5) = 43.5/8 = 5.44 (this is rounded)..so he has already biked 5.44 miles
14.5 - 5.44 = 9.06 miles <== this is how many miles he has left to bike
or this way...
if he already biked 3/8, then he has 5/8 left to bike
5/8 (14.5) = 9.06 miles
