Answer:
7850 mi
Step-by-step explanation:
Area of a circle is:
A = (pi)r²
A = (3.14) (50²)
A = (3.14) (2500)
A = 7850 square miles
Step-by-step explanation:
Looking at the graph, if you plot the point (-1,-4) you'll see that the point is on the area(red one, in the graph I attached) the graph covers, you can also put x=-1 and y=-1 to check if it's true or not
Multiply numerator and denominator by sin(x) * cos(x), getting:
((sin(x) * cos(x)) - cos^2(x) / (((sin^2(x)) - (sin(x) * cos(x))) =
(cos(x) * (sin(x) - cos(x)))
------------------------------------
(sin(x) * (sin(x) - cos(x)))
and after you cancel the two identical terms (sin(x) - cos(x)), you have:
cos(x)
----------- = cot(x) <--------------- Answer
sin(x)
