7 & 8/10 or 78/10 ( which is the same thing)
What question are you trying to ask?
W=2L-3
W*L=193
replace W with 2L-3: (2L-3)L=193
2L^2-3L-193=0
Cannot factor
are you sure the numbers are correct?
If it cannot be factored, use the quadratic formula to find out L, then you can find out W
use the Pythagorean theorem to find the diagonal. I don't see an easier way.
Answer:
i saed to answer it and it didnt show me the image so im conf
Step-by-step explanation:
so probably they are, unlees one is acxute and the other is obtuse then.... ur on ur own buddy,
An alternating series
converges if
is monotonic and
as
. Here
.
Let
. Then
, which is positive for all
, so
is monotonically increasing for
. This would mean
must be a monotonically decreasing sequence over the same interval, and so must
.
Because
is monotonically increasing, but will still always be positive, it follows that
as
.
So,
converges.
