Step-by-step explanation:
pythagoras theorem: c²=a²+b²
Where c= longest side of a right angle triangle
AB= 6+r = c
AD= 12 =a
CD= r =b
(6+r)² = 12²+ r²
36+12r+r² =144 +r²
12r+r²-r²=144-36
12r=108
r= 108/12
r=9
Answer:
The domain of the given function is
{x | x= -4,-1, 3, 5, 6}
Im pretty sure that it would be a 1 out of 52, so go with D.
Answer: C= 100+7n
