The roots of the quartic polynomial f(x) = x⁴ + 8x³ + 11x² - 9x + 28 are ±1, ±2, ±3, ±4, ±7, ±14, ±28

In the given problem, we have to find the roots of the fourth degree polynomial and factorize the given polynomial equation first in order to obtain three equations which are linear and quadratic equation. We can easily determine the zeros of the  fourth degree polynomial.

Generally, polynomials of fourth degrees are called quartic polynomials.

f(x) = x⁴ + 8x³ + 11x² - 9x + 28

When we factorize this, we wouldn't get a lower value because this quartic polynomial cannot be factorized.

However, we can still find the roots which are the solution to the polynomial and are

x = ±1, ±2, ±3, ±4, ±7, ±14, ±28

These values are the solution to the polynomial.

Answer:

the probability that the mean number of pieces in a sample of 28 scoops is more than 350 pieces is approximately 0.0228

Step-by-step explanation:

To find the probability that the mean number of pieces in a sample of 28 scoops is more than 350 pieces, we can use the normal distribution.

The standard error of the mean for a sample of size 28 is the standard deviation of the population divided by the square root of the sample size, or 16 / sqrt(28) = 2.8.

This means that the distribution of the sample means is approximately normally distributed with a mean of 344 pieces and a standard error of 2.8 pieces.

To find the probability that the sample mean is more than 350 pieces, we can use the cumulative distribution function of the normal distribution. In this case, we want to find the probability that a normally distributed random variable is greater than 350.

Using a normal distribution calculator or table, we can find that the probability that a normally distributed random variable with a mean of 344 and a standard error of 2.8 is greater than 350 is approximately 0.0228.

Therefore, the probability that the mean number of pieces in a sample of 28 scoops is more than 350 pieces is approximately 0.0228.

If Frida chose a blue ball, there is a 3/4 probability that she chose a ball from the first box.

The probability is calculated by dividing the total number of possible outcomes by the number of possible ways the event could occur.

Probabilistic and odds are two distinct ideas.

Odds are determined by dividing the likelihood of an event by the likelihood that it won't.

So, we have:

Initial box:

3 white balls

2 blue balls.

Next box:

4 white balls.

1 blue ball.

If Frida chose a blue ball, the likelihood that she chose a ball from the first box is:

Probability (P) = (required outcome / Total possible outcomes)

Probability of picking the first box : P(F) = 1/2

Probability of not picking the second box :P(S) 1/2

Probability of picking blue from the first box : P(B | F) = 3/5

Probability of picking blue, but not from the first box : P(Blue not from the second box) P(B|S) = 1/5

If Frida chose a blue ball, there is a chance she chose a ball from the first box:

P(F) * P(B|F) ÷ (P(F) * P(B|F)) + (P(S) * P(B|S))

(1/2 * 3/5) ÷ ((1/2 *3/5) + (1/2 * 1/5)

3/10 ÷ (3/10 + 1/10)

3/10 ÷ 4/10

3/10 * 10/4

= 3/4

Therefore, if Frida chose a blue ball, there is a 3/4 chance that she chose a ball from the first box.

The area of the courtyard is given by the expression 24(5x - 1), and the area of the cement walkway is given by the expression 32(5x-1 + 8)- 24(5x-1). To find an equivalent expression for the area of the cement walkway, we can first distribute the 32 and the 24 in the second expression to get:

Area of cement walkway = 32 * (5x-1 + 8) - 24 * (5x-1)

= 32 * 5x-32 - 24 * 5x+24 + 32 * 8 - 24

= 160x-1024 - 120x+576 + 256 - 24

= 40x-448 + 256 - 24

= 40x-192

Therefore, an equivalent expression for the area of the cement walkway is 40x - 192. This expression represents the area of the cement walkway in square yards.

So toms equation is y= 4x + 6 and addisons equation is y=10x so they will meet eachother in 1 hour. You can use a desmos calculator to input the equations for the answer

Answer:

1 hour

Step-by-step explanation:

Let's set up an equation for Tom's and Addison's distances: T(x) = 4x + 6, A(x) = 10x, where x is the amount of time since Addison started (in hours).

We solve for A(x) = T(x) and get:

10x = 4x + 6 → subtract 4x from both sides

6x = 6 → divide both sides by 6

x = 1

Therefore, it took Addison 1 hour to catch up with Tom

Step-by-step explanation:

You want to know the measures of angles ADB and ADC given that inscribed angle BAC is 21° and exterior angle CBE is 58°.

Angle CBE is exterior to triangle CBA with remote interior angles BAC (21°) and ACB. The exterior angle is equal to the sum of the remote interior angles, so ...

  ∠CAB +∠ACB = ∠CBE

  21° +∠ACB = 58°

  ∠ACB = 37° . . . . . . . . subtract 21°

The measure of an inscribed angle is half the measure of the arc it intercepts. This means the measures of all inscribed angles that intercept the same arc are the same.

  ∠ADB = ∠ACB = 37°

  ∠BDC = ∠CAB = 21°

By the Angle Addition theorem, ...

  ∠ADC = ∠ADB +∠BDC = 37° +21°

  ∠ADC = 58°

As we just saw, ...

  ∠ADB = 37°

For angle CAD = 69°, the total of the inscribed angles with vertex A is ...

  ∠CAD +∠CAB = ∠BAD

  69° +21° = 90° = ∠BAD

This means angle BAD intercepts an arc BD of 180°, hence segment BD is a diameter.

What is the supplementary angle?

Angles that add up to 180 degrees are referred to as supplementary angles. For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°.

2.

Given that, ∠1 and ∠4 are vertical angle.

According to the vertical angle theorem, if two angles are vertical then they are congruent.

Therefore,

∠1 = ∠4

3x + 14 = 5x − 52

Subtract 5x from both sides:

3x - 5x + 14 = -52

-2x + 14 = -52

Subtract 14 from both sides:

-2x = -66

x = -33

Putting x = -33 in ∠1 = 3x + 14

∠1 = 3× 33 + 14 = 113°

3.

Given that, ∠1 = 3x + 8 and ∠2 = 2/3x + 62 are supplementary angles.

Therefore ∠1 + ∠2 = 180°

3x + 8 + 2/3x + 62 = 180°

11/3 x + 70 = 180°

Subtract 70 from both sides:

11/3 x = 110

x = 110 × (3/11)

x = 30

Putting x = 30 in ∠1 = 3x + 8 and ∠2 = 2/3x + 62

∠1 = 3x + 8 = 3×30 + 8 = 98°

∠2 = 2/3x + 62 = (2/3)×30 + 62 = 82°

4.

Given that, Angle 2 and Angle 3 are vertical angles. If the measure of angle 2 equals 13x + 27 and the measure of angle 3 equals 9x + 59.

Therefore,

∠2  = ∠3

13x + 27 = 9x + 59

Subtract 9x from both sides:

13x - 9x + 27 = 9x -9x +59

4x +27 = 59

Subtract 27 from both sides:

4x = 32

x = 8

5. Given that m∠ABC = 163° and ∠XYZ = 5x + 2 are supplementary angles.

m∠ABC + m∠XYZ =180°

Answer:

2)  m∠1 = 113°

3)  98° and 82°

4)  x = 8  

    Angles = 131°

5)  x = 3

Step-by-step explanation:

If Angle 1 and Angle 4 are vertical angles, then according the Vertical Angles Theorem they are congruent.

Therefore:

⇒ m∠1 = m∠4

⇒ 3x + 14 = 5x - 52

⇒ -2x + 14 = -52

⇒ -2x = -66

⇒ x = 33

To find the measure of Angle 1, substitute the found value of x into the expression for the angle:

⇒ m∠1 = 3x + 14

⇒ m∠1 = 3(33) + 14

⇒ m∠1 = 99 + 14

⇒ m∠1 = 113°

Given:

If the angles are supplementary, they sum to 180°:

⇒ 3x + 8 + ²/₃x + 62 = 180

⇒ ¹¹/₃x + 70 = 180

⇒ ¹¹/₃x = 110

⇒ 11x = 330

⇒ x = 30

Substitute the found value of x into the expressions for the angles:

⇒ ∠ = 3x + 8

⇒ ∠ = 3(30) + 8

⇒ ∠ = 98°

⇒ ∠ = ²/₃x + 62

⇒ ∠ = ²/₃(30) + 62

⇒ ∠ = 82°

If Angle 2 and Angle 3 are vertical angles, then according the Vertical Angles Theorem they are congruent.

Therefore:

⇒ m∠2 = m∠3

⇒ 13x + 27 = 9x + 59

⇒ 4x + 27 = 59

⇒ 4x = 32

⇒ x = 8

Substitute the found value of x into the expressions for the angles:

⇒ m∠2 = 13x + 27

⇒ m∠2 = 13(8) + 27

⇒ m∠2 = 104 + 27

⇒ m∠2 = 131°

⇒ m∠3 = 9x + 59

⇒ m∠3 = 9(8) + 59

⇒ m∠3 = 72 + 59

⇒ m∠3 = 131°

Given:

If ∠ABC and ∠XYZ are supplementary, they sum to 180°:

⇒ m∠ABC + m∠XYZ = 180°

⇒ 163 + 5x + 2 = 180

⇒ 5x + 165 = 180

⇒ 5x = 15

⇒ x = 3

The side length of Figure B is 14 feet. Using these values, the corresponding side length of Figure A can be calculated to be 7 feet.

The missing corresponding side length of Figure A can be determined using the ratio of areas and the known side length of Figure B. If two shapes are similar, then their corresponding sides are in the same ratio as their areas. Since the area of Figure A is 18 square feet and the area of Figure B is 98 square feet, the ratio of their areas is 18/98. Since the side length of Figure B is 14 feet, the corresponding side length of Figure A can be calculated by multiplying 14 feet by the ratio of 18/98, which is 0.1837. This value can be rounded to 7 feet. Therefore, the missing corresponding side length of Figure A is 7 feet. This result can be verified by calculating the area of Figure A using the known side length and the missing side length.
