Write The Simplest Polynomial Function With The Given Zeros 2 2, 5 And -3

Answers

Answer 1

Answer:

A. P(x) = x⁵ + 3x⁴ - 13x³ - 39x² + 40x + 120

Step-by-step explanation:

With the given zero's, the polynomial is:

P(x) = (x - 2√2)(x - √5)(x + 3)

Open parenthesis in steps:

1. (x - 2√2)(x - √5) = x² - (2√2 + √5)x + 2√10 = x² - 2x√2 - x√5 + 2√10

2. (x² - 2x√2 - x√5 + 2√10)(x + 3) =

x³ - 2√2x² - √5x² + 2√10x + 3x² - 6√2x - 3√5x + 6√10 =

x³ + 3x² - 2x²√2 - x²√5 - 6x√2 - 3x√5 + 2x√10 + 6√10

This is not matching any options so we add two more zero's: -2√2 and -√5

New polynomial looks like:

P(x) = (x - 2√2) (x + 2√2)( x - √5)(x - √5)(x + 3)

Open parenthesis in steps:

1. (x - 2√2) (x + 2√2) = x² - 82. (x - √5) (x + √5) = x² - 53. (x² - 8)(x² - 5) = x⁴ - 8x² - 5x² + 40 = x⁴ - 13x² + 404. (x⁴ - 13x² + 40)(x + 3) = x⁵ + 3x⁴ - 13x³ - 39x² + 40x + 120P(x) = x⁵ + 3x⁴ - 13x³ - 39x² + 40x + 120

Find a point E on CD such that the ratio of CE to CD is [tex]\frac{3}{8}[/tex].

Answers

Answer:

Sorry if it’s wrong. But I think the answer is: -3

Step-by-step explanation:

Formula:

E= x1 + a/b (x2 -x1)

E=-9 + 3/8(7+9)

E= -9 + 3/8(16)

E= -9 + 6

E= -3

The location of point E will be at negative  3. Then the correct option is C.

What is the section of the line?

Let A (x₁, y₁) and B (x₂, y₂) be a line segment. Then the point P (x, y) divides the line segment in the ratio of m:n. Then we have

x = (mx₂ + nx₁) / (m + n)

y = (my₂ + ny₁) / (m + n)

The information is given below.

CE / CD = 3 / 8

CE / ED = 3 / 5 = m / n

Then the location of the point E will be

x = [3 × (7) + 5 × (-9)] / (3 + 5)

x = (21 - 45) / 8

x = - 24 / 8

x = -3

Thus, the location of point E will be at negative  3. Then the correct option is C.

Step-by-step explanation:

r = E/I

IF the bottom number of a fraction is multiplied the it's whole number version, the bottom of the fraction is gone and the letter moves to the other side

I*r = E/I * I

IR = E

divide both sides by R to get I by itself

IR/R = E/R

I = E/R

Isaac wants to play miniature golf. Go Golf charges $2.50 for ball and club rental and $4.25 per game. Golf Games charges $3.25 for ball and club rental and $8.50 for two games. For how many games would the cost be the same? Write and solve an equation to determine the number of games for which the cost would be the same.​

Answers

The cost would be the same for 47 Go golf and 54 golf games.

What is the Multiplication operation?

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

Given data as:

Charges for Go Golf -

Renting a ball and a club costs $2.50.

$4.25 for one game and

Charges for Golf Games -

3.25 for the rental of a ball and a club

$8.50 for two games

We have to determine the number of games would the cost be the same.

Total charges of Go golf per game = $2.50 + $4.25 = $6.75

Total charges of Golf game for 2 games = $3.25 + $8.50  = $11.75

For per game = $11.75 / 2 = $5.875

Let the game would be x for  Go golf and

And let game would be y for the golf game

As per the given condition,

6.75 x = 5.875y

27/4 x = 47/8 y

Apply cross multiplication operation,

54x = 47y

x/y = 47 / 54

x = 47

So y = 54.

Hence, the cost would be the same for 47 Go golf and 54 golf games.

The cost would be the same for 47 games at Go Golf and 54 games at Golf Games.

Total charges of Go golf per game = $2.50 + $4.25 = $6.75

Total charges of Golf game for 2 games = $3.25 + $8.50  = $11.75

Cost per game at Golf Games

= Total charges for 2 games / 2

= $11.75 / 2

= $5.875

Let the number of games be x for Go Golf and y for Golf Games.

As per the given condition,

6.75x = 5.875y

To find the relation between x and y, cross-multiplication can be used:

27/4 x = 47/8 y

54x = 47y

x/y = 47/54

Comparing the value gives

x = 47 and y = 54.

Hence, the cost would be the same for 47 games at Go Golf and 54 games at Golf Games.
