Answer:


Step-by-step explanation:
A parallelogram is a quadrilateral (4-sided polygon) that has two pairs of parallel sides.
In this sense, this figure shows a especial parallelogram called <u>rectangle</u>, since its four sides form right angles (
).
Hence:






So, the correct choices among the given options are:


Answer: 88
Step-by-step explanation:
a. Note that
is continuous for all
. If
attains a maximum at
, then
. Compute the derivative of
.

Evaluate this at
and solve for
.




To ensure that a maximum is reached for this value of
, we need to check the sign of the second derivative at this critical point.

The second derivative at
is negative, which indicate the function is concave downward, which in turn means that
is indeed a (local) maximum.
b. When
, we have derivatives

Inflection points can occur where the second derivative vanishes.




Then we have three possible inflection points when
,
, or
.
To decide which are actually inflection points, check the sign of
in each of the intervals
,
,
, and
. It's enough to check the sign of any test value of
from each interval.




The sign of
changes to either side of
and
, but not
. This means only
and
are inflection points.
Answer: 0
35X +14=3X +14
35X = 3X
35X-3X=0
32X = 0 divide both sides by 32
x=0
There could be 14 different groups of 2 players.
All you have to do to find out how many different groups there could be is to multiply 7 (players) by 2 (groups).
7 x 2 = 14
Hope this helped! :D
