Answer:
I tried to answer but I still would like to know what doesn't make sense.
Considering the identity:
The identity is true whenever both sides are defined. It is not supposed to hold the values when we have division by zero, because it is undefined.
If the value doesn't make sense, it is probably not a function, or it is undefined by the given value of .
Let's go back to the definition of function again:
A function relates a set of inputs and a set of allowable outputs where each input is related to only one output. It basically defines the relation of ordered pairs.
Hope it helped you a bit.
Answer: rectangle.
Step-by-step explanation:
Given points: K(0,0) I(2,2) T(5,-5) E(7,-3)
Distance formula to find distance between and :
i.e. KI = TE and KT= IE, so opposite sides equal.
It can be a parallelogram or rectangle. [if all sides are equal it would be square or rhombus]
IT= KE, i.e. diagonals are equal.
It means KIET is a rectangle.
Answer:
ist the question
Step-by-step explanation:
write question first
First, pull out a factor of
.
Notice that when
(which you can arrive at via the rational root theorem), you have
which means you can pull out a factor of
. Upon dividing you get
The rational root theorem will come in handy again, suggesting that
appears a second time as a root, which means
Now this is more readily factored without having to resort to the rational root theorem. You have
so in fact,
shows up as a root for a third time.
So, you have
Two roots are obvious,
and
(with multiplicity 3). The remaining two are given by
