Answer:
the answer for this is A
Step-by-step explanation:
B,D,Erespectively representing the numbers are: 8,16,19.
8 as seen is the lowest.
16 as seen is the median .
19 as seen is the greatest.
Therefore the answer is A.
I only know the answer for B. so the answer for B is 43.3
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:
Rotha
Step-by-step explanation:
20 divided by 10 is 2
30 divided by 12 is 2.5
So Rotha is quicker
