we have that
(r, ∅)----------> (-7, 5 pi/3)
we know that
5 pi/3--------> 300°-----------> -60°
To convert polar cordinates in rectangular one with use the following formula:
x=r*cos ∅------> x=-7*cos -60°-------> x=-7*(1/2)------> x=-7/2
y=r*sin ∅-------> y=-7*sin -60-------> y=-7*(-√3)/2----> y=7√3/2
the answer is the option
D) ordered pair negative 7 divided by 2 comma 7 square root 3 divided by 2
Change your percents to decimals, then multiply 100 by your 12% decimal, then multiply 79.74 by your 7.25% and you should get the answer
The area equals 38 because the total area is 40 and the area of the white part is 2 and 40-2=38 so the area of the green area is 38
