Lateral area is the area of the faces, while surface area is the area of the faces and and bases.
Answer:
I'm guessing none because the discrimant (sqrt of b squared - 4ac is less than zero, signifying it has no real roots
Step-by-step explanation:
have a happy holidays!
Answer:
-2
Step-by-step explanation:
In a linear regression model we have the equation
that relates
and
, where
is the estimator of the slope and
is the estimator of the Y-intercept. The coefficients
and
can be estimated with the equations:

. Thus,

ANSWER TO QUESTION 1
.
EXPLANATION
The function given to us is,

According to rational roots theorem,
are possible rational zeros of
.
We find out that,




Also




This implies that
are factors of
and hence
is also a factor.
We perform the long division as shown in the diagram.
Hence,
.
ANSWER TO QUESTION 2
Sketching the graph
We can see from the factorization that the roots
and
have a multiplicity of 1, which is odd. This means that the graph crosses the x-axis at this intercepts.
Also the root
has a multiplicity of 2, which is even. This means the graph does not cross the x-axis at this intercept.
Now we determine the position of the graph on the following intervals,









We can now use these information to sketch the function as shown in diagram
