R^2 = [tCos(t)]^2 + [tSin(t)]^2 = t^2(Sin(t)^2 + Cos(t)^2) = t^2
So the curve is a circle with the center at the origin.
When t=pi, x=-1 is the equation of the tangent to the curve at that point.

</h3><h3>1.) <u>Graph:</u></h3>
- Since we know
, you graph 
on the 
-axis. And this is an ending, meaning it doesn't go on forever.
- However, we don't know what
is. So because we don't know what is we still graph it but it'll go on forever.
<em> - You can either graph this like this, OR graph this using desmos.com. </em>
<h3><u /></h3><h3><u>Vertical or Horizontal?</u> </h3>
Horizontal, Left and Right.
- <em />
<em> </em>Vertical, Up and Down.
- So since we know is, (Horizontal,) we have to graph , (Vertical.) So to sum this up, this just means whatever variable you don't know yet, that will be the one that you graph as an infinite.

Answer:
Neither the ranges nor the interquartile ranges for the data sets are the same.
Step-by-step explanation:
In a visual display, the boxplot presents five sample statistics: the minimum, the lower quartile, the median, the upper quartile and the maximum, and the box length gives an indication of the sample variability and the line across the box shows where the sample is centred, with an end at each quartile. The length of the box is thus the interquartile range of the sample and, whether the sample is symmetric or skewed, either to the right or left, the "shape" of the sample, and by implication, the shape of the population from which it was drawn, considering appropriate analyses of the data.
