Step-by-step explanation:
If we convert
to a Cartesian equation,
So we have a circle with center (-5,0), with a diameter of 10.
Answer:
4th option
Step-by-step explanation:
angle CBE and Angle EBG
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.
ACUTE ANGLE.
this is because the angle is less than 90 degree and greater than 0 degree
There would be 8 tigers in the exhibit. Hope this helps.
