Answer:
A rational expression that has the nonpermissible values
and
is
.
Step-by-step explanation:
A rational expression has a nonpermissible value when for a given value of
, the denominator is equal to zero. In addition, we assume that both numerator and denominator are represented by polynomials, such that:
(1)
Then, the factorized form of
must be:
(2)
If we know that
, then the rational expression is:
(3)
A rational expression that has the nonpermissible values
and
is
.
Answer: The angles of ΔA'B'C are congruent to the corresponding parts of the original triangle.
Step-by-step explanation:
Given : Triangle ABC was rotated 90 degrees clockwise. Then it underwent a dilation centered at the origin with a scale factor of 4.
A rotation is a rigid transformation that creates congruent images but dilation is not a rigid transformation, it creates similar images but not congruent.
Also, the corresponding angles of similar triangles are congruent.
Therefore, The angles of ΔA'B'C are congruent to the corresponding parts of the original triangle.
Answer:
80 degrees
Step-by-step explanation:
We can use the Central Angle Theorum, which states that if the vertex of the angle is the center of the circle, then the arc is the same measurement as the angle.
In this case, m<COB is 80 degrees, and the vertex is the center of the circle, which means that measure of arc CB is also 80 degrees
Answer:
The answer should D) I, II, and III
The Median should be your best answer.
Usually, using the mean would be best, however, note that one of the numbers is larger than all the others ($1,110,000), and so will throw the median off. This means that median would be your best choice.
hope this helps
