Answer:

(D) and (E)

Step-by-step explanation:

From the properties of square, we know that all the four sides of the square are always congruent, the diagonals of the square are always equal and the four angles of the square are equal and are of the measure 90°.

Therefore, from the options, D and E are the correct ones because the sides of square are congruent and the angles are also congruent but the diagonals are not perpendicular.

When using the rational root theorem, which of the following is a possible root of the polynomial function below f(x)=x^3-5x^2-1
uranmaximum [27]

Answer:

\Large \boxed{\sf \ \ 7 \ \ }

Step-by-step explanation:

Hello, please consider the following.

The polynomial function is

x^3-5x^2-12x+14

The rational root theorem states that each rational solution

   x=\dfrac{p}{q}    

, written in irreducible fraction, satisfies the two following:

   p is a factor of the constant term

   q is a factor of the leading coefficient

In this example, the constant term is 14 and the leading coefficient is 1. It means that p is a factor of 14 and q a factor of 1.

Let's proceed with the prime factorisation of 14:

14 = 2 * 7

Finally, the possible rational roots of this expression are :

   1

   2

   7

   14

and we need to test for negative ones too

   -1

   -2

   -7

   -14

From your list, the correct answer is 7.

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Answer: \frac{6}{2}

Step-by-step explanation:

1. Use this \frac{f(b)-f(a)}{b-a} to find the average rate of change

2. Average rate of change = \frac{f(8)-f(6)}{8-6}

3. f(8) = - 4 and f(6) = -10 (To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))

4. Replace -4 to f(8) and -10 to f(6)

5. So it will look like\frac{-4-(-10)}{8-6}

6. Solve \frac{6}{2}
