Find all roots of the polynomial function f(x) = 2x^4-x^3-13x^2+5x+15

Answers

Answer 1

Answer:

Roots are :  1, -7 and -7

Step-by-step explanation:

When we put x = -1 in F(x) it is equal to 0

Thus, (x + 1) is factor of given function.

When we divide F(x) by (x + 1) it gives the value (x² - 6x - 7)

factorizing the work  x² - 6x - 7 by middle term splitting.

> x² - 6x - 7 = x² - 7x + x - 7

>  x(x - 7) + 1(x - 7)

>  (x + 1) (x - 7)

then,  x³ - 5x² - 13x - 7 = (x + 1)(x + 1)(x - 7)

x = -1, -1, 7 the factor.

D and C is the answers.

Answers

Answer:

171 m

Step-by-step explanation:

Okay, so we have to find the area of all the shapes that make up the prism:

I'm going to start with the side rectangles:

5 x 7 = 35

There's 2 of them so:

35 x 2 = 70

Now let's go onto the side triangles:

4 x 6 = 24 (normally it would then be ÷ 2, but because there's 2 triangles, you don't have to do that)

Then we do the bottom rectangle:

6 x 7 = 42

So, adding them all together:

35 + 70 + 24 + 42 = 171

So the surface area of the prism is 171 m

hope this is right:)

Two numerical patterns are shown below:

Pattern A: 6, 12, 18, 24, 30
Pattern B: 12, 24, 36, 48, 60

Select the statement that describes the numerical patterns.

The rule for Pattern B is "multiply by 2."
The rule for Pattern A is "multiply by 2."
Each term in Pattern B is one half the corresponding term in Pattern A.
Each term in Pattern A is one half the corresponding term in Pattern B.

Answers

it’s each term in pattern B is one half the corresponding term in Pattern A because half of 12 is 6 and half of 24 is 12 and so on so on

The correct numerical patterns are shown would be,

⇒ Each term in Pattern A is one half the corresponding term in Pattern B.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We have to given that;

Two numerical patterns are shown below:

Pattern A: 6, 12, 18, 24, 30

Pattern B: 12, 24, 36, 48, 60

Now, We get;

⇒ 12 / 2 = 6

Thus, Each term in Pattern A is one half the corresponding term in Pattern B.

Therefore, Each term in Pattern A is one half the corresponding term in Pattern B.

4 would be 47 because of outer exterior angles

Answer:

so basically these angles in the first pictures would be the same so it would equal 53 degrees and in the second picture they would also be the same so 47 degrees. is the angles dont look the same then youd subtract the number you have from 180 and that would equal up too the next angle but if your angles look like the same they will be.

Answers

Answer:

90 - x

Step-by-step explanation:

90 - 80 = 10

90 - 25 = 65

90 - 54 = 36

90 - x

The other angles of these complementary pairs are 10°, 65°, 36°,        (90-x)°.

What is complementary angle?

Two angles are Complementary when they add up to 90 degrees (a Right Angle). The two angles can be part of the same or different figures.

For the given situation,

The table shows the degree measures of two complementary angles.

We need to find the other angle, which when added sums up 90°.

1.  One angle = 80°

Another angle = [tex]90-80[/tex]

⇒ [tex]10[/tex]°

2. One angle = 25°

Another angle = [tex]90-25[/tex]

⇒ [tex]65[/tex]°

3. One angle = 54°

Another angle = [tex]90-54[/tex]

⇒ [tex]36[/tex]°

4. One angle = x°

Another angle = [tex]90-x[/tex]

⇒ [tex](90-x)[/tex]°

Hence we can conclude that the other angles of these complementary pairs are 10°, 65°, 36°, (90-x)°.
