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
What is the slope of a line is parallel to y=(1/2)x=3

<h2>Answer:</h2>
<em>You will bike 30.2 miles in the seventh day according to the prediction.</em>
<h2>Explanation:</h2>Here we have the following data, You bike
- 5 miles the first day of your training,
- 5.4 miles the second day,
- 6.2 miles the third day, and
- 7.8 miles the fourth day.
So we can know some facts:
- From the first day to the second day the number of miles increases:
- From the second day to the third day the number of miles increases:
- From the third day to the fourth day the number of miles increases:
By taking a look at the pattern, we can see that each day you increases the number of miles by a factor of 2 compared to the previous day. So:
- From the fourth day to the fifth day the number of miles increases:
- From the fifth day to the sixth day the number of miles increases:
Finally:
- From the sixth day to the seventh day the number of miles increases:
