Make a table with the angle theta as independent variable and the radius r as dependent variable:
theta radius = 4+2cos theta radius
------- -----------------------------------------
0 4+2 6
pi/6 4+2cos pi/6 = 4+2(sqrt(3)/2
Perhaps you have already plotted this using webassign (but remember that you have not shared an illustration here). (Please don't type "webassign plot" repeatedly, as it accomplishes nothing.)
Generally, when one wishes to find the area of a region defined by polar functions (as is the case here), one first determines suitable limits of integration from the finished curve and checks them through actual integration.
Which formula should you use to find the area: Look up "areas in polar coordinates," as I did. The formula is as follows:
Enclosed area = Integral from alpha to beta of (1/2)r^2 d(theta). Note that the initial radius here is 6 (since r = 4 plus 2 cos theta is 4+2 when theta = 0).
Answer:
Angle 1 is 105°
Angle 2 is 75°
Step-by-step explanation:
Angle 2 is the same angle as angle 6 which is 75°
Angle 1 can be found by subtracting 75° (angle 2) from 180° which is the angle of a straight line. Which equals 105°.
Hope this helps! :)

Answer:
672 meters so very fast
Step-by-step explanation:
12*8=96
3*8=24^2=576
96+576=672
A statistical question is a question isn't too vague nor too broad and can be used to collect statistics and data to answer the question.
An example of this is "In inches, how tall are the giraffes in Exhibit 4 of the Mars Zoo?" Of course, the Mars Zoo isn't real, but this is an example.
The question isn't too vague. If it were, it might only be asking for data from only a single individual. It's also not too broad. Otherwise, it would be asking for much more data, such as all of the exhibits in the zoo, or even the whole world!
This is a great example of a statistical question.
A non-statistical question would be something along the lines of "How much time do team members spend practicing during the off-season?" This question is not a statistical question due to being too broad and the data needed to be collected not specified completely.
In order to create a statistical question, you should first identify what you need to know and what data needs to be collected to answer the question.
The coach wants to know how much times each player on the team spends practicing every week during the off-season. The data that would be collected in this case is time practicing.
Now we can write our statistical question!
Without being too vague or broad, we can ask about how much time, in hours, players on the coach's team spend practicing the sport played by that team during the off-season.
Something like the following question would be a good answer:
"How much time, in hours, do players of the coach's team spend practicing the sport their team plays during the off-season?"
This question isn't too broad. It specifies that only the time data of this specific team spends practicing a single specific sport during a given time range.
The question also isn't too vague, since it specifies the entire team rather than only a couple players, and since it asks for a wider time frame than just a couple days.
Hope this helps!
