The equation of the polar curve 
is an even cosine function.
<h3>Polar curves</h3>
In geometry, polar curves are curves that are represented by the polar coordinates such that they are drawn around a fixed point
The equation of the polar curve is given as:
To graph the polar curve, we make use of the following representations:
- r represents the y-axis
represents the x-axis
Using the above representation, we can graph the polar curve
See attachment for the graph that represents

Answer:
Marci is the faster runner.
Step-by-step explanation:
Sandi can run 348 cm in a second. Let's find out how many cm she can run in a minute: in a minute there are 60 seconds. So lets multiply 348cm times 60, this gives you 20,880. That is how much she travels in a minute, now let's find out how much she runs in an hour: if she runs 20,880 cm in an minute and there are 60 minutes in an hour, then all you have to do is multiply 20,880 times 60, this gives you 1,252,800. That is how many cm she runs in an hour. Now let's change from cm to miles. There are 160,934 cm in a mile. If we divide 1,252,800 by 160,934 this will give you
Hey there!
Since it's 30n, 30 is the coefficient and it's being multiplied by n.
We plug in n.
30(2) =
60
Hope this helps!
