The domain is (-∞,∞)
the range is (−∞,2]
Answer: 90°
Step-by-step explanation:
Angle b is vertical to the angle that has a measure of 90°
It’s A. 38! You divide the diameter in half and use the radius to find the area of the circle
The sum formula for a geometric sequaence is:
sum(n) = a1(1-r^n)/1-r
Where n is the number of terms, a1 is the first term and r is the common ratio:
s(8) = 3(1-1/2^8) / (1-1/2)
s(8) = 3(1-1/256) / 1/2
s(8) = 2 253/256 / 1/2
s(8) = 765/128
The answer is C.
