Check the picture below.
notice, the pairs in the Unit Circle are the (cosine , sine) pair, which are equivalent to (x , y) values in a cartesian plane.
Answer:
x=8
y=11
Step-by-step explanation:
2(8) + 2(11) = 38
8 + 3 = 11
Answer:
-1/4 if you prefer the answer written as a fraction.
-0.25 is you prefer the answer written as a decimal.
Step-by-step explanation:
Common ratio of a geometric sequence can be found by doing term divided by previous term.
That is you could do:
80/-320
or
-20/80
or
5/-20
If all these ratios are not equal, it isn't a geometric sequence and does not have a common ratio.
Let's see what these reduce to:
80/-320=1/-4 =-1/4 or -0.25
-20/80=-1/4 or -0.25
5/-20=1/-4=-1/4 or -0.25
So the common ratio is -0.25 or yo you can write it as -1/4.
Answer:
Step-by-step explanation:
r = 12
V = 4*pi * r^3 / 3
V = 4 * 3.14 * 12^3 /3
V = 4 * 3.14 * 1728 / 3
V = 4 * 5425.92 /3
V = 21703.68/3
V = 7234.56
None of the answers look correct.
