(-2^3) = -8.
-2 times 3 = -6.
The expression is now -6 - (-8).
-6 + 8 = 2.
The answer should be 2.
Answer:
B
Step-by-step explanation:
Here, we want to find which of the expressions is undefined
kindly note that
sin^-1 is arcsin
cos^-1 is arccos
A. arcsin (1) = 90 degrees
B. arcsin (-2) = undefined
c. arccos 0 = 90 degrees
d. arccos (-1) = 180
ANSWER
The circumcenter is (2,1)
EXPLANATION
The midpoint of BC is (-3,2)
The equation of the perpendicular bisector of BC is x=2
The midpoint of AB is (-1,1)
The midpoint of AB is (-1,1)
The perpendicular bisector of AB is y=1.
These two lines intersect at (2,1).
The point of intersection of the perpendicular bisectors of a triangle is called the circumcenter of the triangle.
