The answer to this question should be True. The perpendicular bisector, by definition, is the midpoint between two points that forms a right angle with them. It must be equidistant from R and S in order to be a perpendicular bisector.
It is asking for the length of that leg of the triangle. You would use the Pythagorean theorem. So 11^2+12^2=c^2. The answer is he square root of 265.
Pie is an irrational number because it is 3.14. It is not a even number.
Answer:
First term = -41.
Common difference = -15.
Step-by-step explanation:
nth term: an = a1 + (n - 1)d where a = first term and d = the common difference.
-671 = a1 + (43 - 1)d
-806 = a1 +(52 - 1)d
-671 = a1 + 42d
-806 = a1 + 51d
Subtracting ( to eliminate a1):
-671 - (-806) = 42d - 51d
-9d = 135
d = -15
Substitute for d in the first equation:
-671 = a1 + 42*-15
-671 = a1 - 630
a1 = -671 + 630 = -41.
, we have 
. So we have
