Answer:
2) 2
Step-by-step explanation:
Subtract each equation from each other
x + 2y = 9
<u>-x+ y = -3</u>
<u>3y </u>= <u>6</u>
3 3
So y = 2
Not necessarily. Consider the series
and
. Here
.
The first series converges by the alternating series test, which says
converges if
is a decreasing sequence and converges to 0. This is the case, as
as
, and each term is decreasing. (Indeed the series converges to
.)
On the other hand, the second series is a classic example of a divergent sum.
Assuming the diameter is one, it should be (pi)/2 or 1.57 units.
