The polynomial p(x) = x^3 - 21x - 20 has a known factor of (x-5). Rewrite p(x) as a product of linear factors.

Answers

Answer 1

Answer:

p(x) = (x - 5)(x + 1)(x + 4)

Step-by-step explanation:

Using Synthetic division to find the quotient on dividing p(x) by (x - 5)

5 | 1  0  - 21   - 20 ← 0 to represent the coefficient of x² term

        5    25     20

    -----------------------

     1  5   4        0 ← remainder is zero

quotient = x² + 5x + 4 = (x + 1)(x + 4)

p(x) = (x - 5)(x + 1)(x + 4)

Answer 2

The polynomial p(x) = x^3 - 21x - 20 can be written as a product of linear factors as follows;

(x-5) (x+4) (x+1).

According to the question, the polynomial, p(x) = x^3 - 21x - 20 has a known factor of (x- 5).

To further factorise this polynomial such that it becomes a product of linear factors, we must first, perform the long division of x³ - 21x - 20 divided by (x-5).

The polynomial long division is as in the image attached;

The result of the division of x³ - 21x - 20 by (x-5) yields;

x² + 5x + 4.

The expression, x² + 5x + 4 can however be further factorised so that we have;

x² + 5x + 4 = (x+4) (x-1)

Ultimately, the polynomial p(x) = x^3 - 21x - 20 can be written as a product of linear factors as follows;

(x-5) (x+4) (x+1).

Question 9 (5 points)
Moe has been offered two different summer jobs. Job A would pay him an hourly rate of $12. Job B would pay him $510 for a 40-hour work week. Which job has a higher rate of pay? There isn't enough information to determine which job has a higher rate of pay.
Job B
Job A and Job B have equal rates of pay.
Job A

Answers

Job B, because you divide the total pay (510) and the hours (40), so 510/40= 12.75

Answer:

$12.75

Step-by-step explanation:

Moe has been offered two different summer jobs. Job A would pay him an hourly rate of $12. Job B would pay him $510 for a 40-hour work week. First, you have to set up the problem like this:

$510/40 hr = ?/1 hr

The next step is to either cross multiply or you can divide the numerator and denominator by the denominator number because 40/1 is still going to be 40. That means, $510/40= what number?

Answer: $12.75 per 1 hour

ellie buys a mobile phone in spain €352.50 her brother jack buys an identical phone in japan for ¥39856 work out how much it is in £

Answers

Answer:

a) The best deal was in Japan

b) The difference is £38

Step-by-step explanation:

First, find out the cost in pounds for both of the purchases.

Japan:

          39856 / 188 = 212.

          the Japanese phone cost £212.

Spain:

          352.50 / 1.41 = 250.

          the Spanish phone cost £250.

Then, subtract the costs to find the difference:

          250 - 212 = 38

The Identical phone in Japan is €28163.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Price of the phone in Spain = €352.50

Price of the phone in Japan = ¥39856

Now,

€1 = ¥141.52

Multiply 39856/141.52 on both sides.

39856/141.52 x 1€ = 39856/141.52 x ¥141.52

€28163 = ¥141.52

Thus,

The cost of a phone in Japan is €28163.

Triangle ABC was translated according to the rule (x, y) = (x + 1.5, y-3.5) to create the image AA'B'C' shown on the
coordinate plane
Which graph shows the pre-image, ABC?

Answers

Answer:

Option D

Step-by-step explanation:

Hope this helps! :)

The coordinates of the preimage will be at A(-2.5, 5.5), B(-2.5, 2.5) and C (-6.5, 2.5)

What is translation?

Translation is a transformation technique for changing the size and position of an object on the x-y plane.

From the given diagram, the coordinate A'B'C' is given as:

A' = (-1, 2)

B' = (-1, -1)

C' = (-5, -1)

If the triangle ABC was translated according to the rule (x, y) = (x + 1.5, y-3.5) to create the image A'B'C'

A (x + 1.5, y-3.5) = (-1, 2)

x + 1.5 = -1

x = -2.5

y - 3.5 = 2

y = 5.5

Hence A = (-2.5, 5.5)

B = (x + 1.5, y-3.5) = (-1, -1)

x + 1.5 = -1

x = -2.5

y - 3.5 = -1

y = 2.5

Hence B = (-2.5, 2.5)

C (x + 1.5, y-3.5) = (-5, -1)

x + 1.5 = -5

x = -6.5

y - 3.5 = -1

y = 2.5

Hence C = (-6.5, 2.5)

Hence the graph that shows the pre image ABC is attached below

John runs 5 miles in 3/4 of an hour.
At the same pace, how many hours will
it take him to run only 1 mile?

Answers

Final answer:

John's speed is 6.67 miles per hour. Therefore, it would take him approximately 0.15 hours or 9 minutes to run 1 mile at the same pace.

Explanation:

The subject of this problem is rate. We can calculate John's speed by dividing the distance he covers by the time it takes. In this case, John ran 5 miles in 3/4 of an hour. So, his speed is 5 miles divided by 3/4 hour, which equates to 6.67 miles per hour. This means he runs 6.67 miles in 1 hour.

Given that speed is constant, if John wants to run only 1 mile, we simply divide this distance by his speed. So, 1 mile divided by 6.67 miles per hour gives 0.15 hours, or approximately 9 minutes. So, it would take John about 0.15 hours or 9 minutes to run 1 mile at the same pace.

What is the equation of the line?

Answers

Answer:

y = 1/4x - 3.

Step-by-step explanation:

We see that the line passes through the points (4, -2) and (0, -3) so the slope is (-3 - (-2) / (0-4)

= -1 / -4

= 1/4 = the slope of the line.

The slope-intercept form of a straight line is y = mx + b where m = slope and b = y-intercept. Here the y-intercept is at (0, -3) so b = -3.

So the equation of the line is y = 1/4x - 3.

Option B.

Step-by-step explanation:

The given vertices of triangle ABC are (-1, -1), (-1, -5) and (0.5, -5).

We need to find the coordinates of triangle when it is translated two units left.

So, the rule of translation is

[tex](x,y)\rightarrow (x-2,y)[/tex]

Using this rule, we get

[tex]A(-1,-1)\rightarrow A'(-1-2,-1)=A'(-3,-1)[/tex]

[tex]B(-1,-5)\rightarrow B'(-1-2,-5)=B'(-3,-5)[/tex]

[tex]C(0.5,-5)\rightarrow C'(0.5-2,-5)=C'(-1.5,-5)[/tex]

The vertices of triangle A'B'C' are A'(-3,-1), B'(-3,-5) and C'(-1.5,-5).

Therefore, the correct option is B.

Use the value 3.14 for , and round your answer to the nearest whole number.

Be sure to include the correct unit in your answer.

Answers

Answer: 201 square feet

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a cylinder: π x radius² x height (in our case the length of the pipe)

Since:

Diameter = radius x 2

In our case D =4

4 = 2radius

Radius= 4/2 = 2 ft

Now that we have the radius, we can use the volume formula replacing with the values given:

V = 3.14x 2² x 16 = 3.14 x 4 x16 =200.96 = 201 square feet

What is a Circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the radius of the circle be represented as r

Now , the equation will be

The circumference of the circle C = 28π inches

And , circumference of circle = 2πr

On simplifying , we get

2πr = 28π

Divide by π on both sides , we get

2r = 28

Divide by 2 on both sides , we get

r = 14 inches

Hence , the radius of the circle is 14 inches
