The distance between two points is the number of units between them.
The distance between Q and R is 3.61 units
<em>It is impossible to determine your friend's error, because the steps are not given in the question. So, I will calculate the distance between Q and R, instead.</em>

The distance (d) between two points is:
So, the distance QR is:
Evaluate exponents
Take square root of 13
Hence, the distance between Q and R is 3.61 units

Answer:
D
Step-by-step explanation:
To convert from polar to rectangular form
• x = rcosΘ , y = rsinΘ
• r = 
⇒ r² = x² + y²
Given
r = 8cosΘ
r = 8 × 
( multiply both sides by r )
r² = 8x, hence
x² + y² = 8x ⇒ D
Answer:
10.846 hours
Step-by-step explanation:
