Use the green's theorem area formula, area of upper r equals one half modifyingbelow contour integral with upper c x dy minus y dx , to find the area of the region, r, enclosed by the astroid, bold r (t )equals (5 cosine cubed t )iplus(5 sine cubed t )bold j such that 0 less than or equals t less than or equals 2 pi.

i think 5 miles per hour

step-by-step explanation:

eve and marks ratios are equivalent

step-by-step explanation:

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
