A fourth-degree polynomial with a leading coefficient of 1 has gone through several transformations, including a vertical compression by a scale factor of 1/3 and a reflection across the x-axis. Two of the zero polynomials are -i and 3i.

Find a y-intercept of this polynomial, if it exists

Answers

Answer 1

The y-intercept of the resulting polynomial is equal to - 3.

How to derive a fourth-degree polynomial generated by rigid transformations

Herein we assume that the other two zeros of the polynomial are i and - i 3, otherwise the polynomial will have at least a complex number as coefficient of the expression. This is because we need to find values from a Cartesian plan, whose ordered pairs are real numbers.

Initially, we have the following expression by algebra properties:

f(x) = (x + i) · (x - i) · (x + i 3) · (x - i 3)

f(x) = (x² + 1) · (x² + 9)

f(x) = x⁴ + 10 · x² + 9

Then, we proceed to use the two rigid transformations described in the statement. Please notice that rigid transformations are transformations applied on polynomials such that Euclidean distance is conserved:

Vertical compression

f'(x) = (1 / 3) · f(x)

f'(x) = (1 / 3) · (x⁴ + 10 · x² + 9)

f'(x) = (1 / 3) · x⁴ + (10 / 3) · x² + 3

Reflection across the x-axis

g(x) = - f'(x)

g(x) = - (1 / 3) · x⁴ - (10 / 3) · x² - 3

The y-intercept is found for x = 0:

g(0) =  - (1 / 3) · 0⁴ - (10 / 3) · 0² - 3

g(0) = - 3

The y-intercept of the resulting polynomial is equal to - 3.

To the nearest whole number, what is the surface area of the right triangular prism?

Answers

Answer: 797.4 m²

Step-by-step explanation:

The surface area is just the total of the areas of each face of of a solid. In this solid, we have 2 triangles and 3 rectangles.

Triangles

We know that the two triangles of this solid are congruent, so they will have the same area. Since the area of a triangle is [tex]\frac{1}{2}bh[/tex], two triangles would have an area of [tex]bh[/tex]. Hence, the total area is

[tex]A=9 * 15\\A=135[/tex]

Rectangles

The area of a rectangle is lw, where l is the length and w is the width. Let's find the total area of all of them.

[tex]A=9*16+15*16+17.4*16[/tex]

All of the areas are a product of some number and 16. This makes sense as the length of this prism is 16. We can un-distribute this 16 to make the calculation easier.

[tex]A=16(9+15+17.4)\\A=16(41.4)\\A=662.4[/tex]

Total

We can add both totals to get the total surface area of the solid.

[tex]135+662.4\\=797.4[/tex]

The surface area of this right triangular prism is 797.4 m².

Which is the inequality in factored form that represents the region greater than or equal to the quadratic function with zeros –3.5 and 11.5 and includes the point (8.5, –54) on the boundary?

Answers

The inequality is represented by the polynomial y ≥ 3.6 · (x - 11.5) · (x + 3.5).

What is the expression of the quadratic inequality?

Herein we must derive the quadratic expression within an inequality of the y ≥ f(x) based on its two roots and a known point on the curve. We can find the coefficients of the quadratic equation by solving this system of linear equations:

(x₁, y₁) = (- 3.5, 0)

12.25 · a - 3.5 · b + c = 0       (1)

(x₂, y₂) = (11.5, 0)

132.25 · a + 11.5 · b + c = 0       (2)

(x₃, y₃) = (8.5, - 54)

72.25 · a + 8.5 · b + c = - 54     (3)

The solution of the system is a = 3.6, b = - 54, c = 144.9. Thus, the inequality is represented by the polynomial y ≥ 3.6 · x² - 54 · x + 144.9, whose factored form is determined by the quadratic formula:

y ≥ 3.6 · (x² - 15 · x + 40.25)

Answer:

B.) f⁻¹(x) = (1/9)x - 7/9

Step-by-step explanation:

Remember, f(x) is another way of writing "y". The inverse can be found by swapping the positions if the "x" and "y" variables and then solving to isolate the "y" variable.

f(x) = 9x + 7                            <----- Original function

y = 9x + 7                               <----- Substitute f(x) for "y"

x = 9y + 7                               <----- Swap variable positions

x - 7 = 9y                                <----- Subtract 7 from both sides

(x - 7) / 9 = y                           <----- Divide both sides by 9

(1/9)x - 7/9 = y                      <----- Divide each term individually by 9

Answers

x > 1 is the required solution of the given inequality - 3x + 7 < 4. This can be obtained by solving the inequality the same way as we solve an algebraic equation.

Solve the inequality:

The inequality can be solved as the same way as we solve an algebraic equation.

Combine the terms with variables to one side and constants to other side.To multiply the whole inequality with negative terms we reverse the sign of the inequality.

Here in the question the inequality to be solved is given:

- 3x + 7 < 4

By subtracting 7 from both sides of the inequality we get,

⇒ - 3x + 7 - 7 < 4 - 7

⇒ - 3x < - 3

To make the side of the inequality with variable x positive we multiply the whole equation with - 1, then we have to reverse the sign of inequality since we have to multiply the whole inequality with a negative term,

we get,

⇒ 3 x > 3

Now finally by dividing the whole inequality by 3 we get,

x > 1

The number line representation can be done by marking values from 1 to numbers greater than 1.

Hence x > 1 is the required solution of the given inequality - 3x + 7 < 4.

4. 6p + 22 = 4
5. 84 = 51 + 11c

Answers

===> Exercise 13k − 8 = 7

Add 8 to both sides.

3k = 7 + 8

Add 7 and 8 to get 15.

3k = 15

Divide both sides by 3.

k = 15 / 3

Divide 15 by 3 to get 5.

k=5 ===> Answer

===> Exercise 28b + 9 = −15

Subtract 9 from both sides.

8b= −15 − 9

Subtract 9 from −15 to get −24.

8b = −24

Divide both sides by 8.

b = -24 / 3

Divide −24 entre 8 para obtener −3.

b=−3 ===> Answer

===> Exercise 38 = 3x − 13

Swap the sides so that all the terms of the variables are on the left side.

3x −13 = 8

Add 13 to both sides.

3x = 8 + 13

Add 8 and 13 to get 21.

3x = 21

Divide both sides by 3.

x = 21 / 3

Divide 21 by 3 to get 7.

x = 7 ===> Answer

===> Exercise 46p + 22 = 4

Subtract 22 from both sides.

6p = 4 − 22

Subtract 22 from 4 to get −18.

6p = −18

Divide both sides by 6.

p = -18 / 6

Divide −18 entre 6 para obtener −3.

p = −3 ===> Answer

===> Excercise 584 = 51 + 11c

Swap the sides so that all the terms of the variables are on the left side.

51 + 11c = 84

Subtract 51 from both sides.

11c = 84 − 51

Subtract 51 from 84 to get 33.

11c = 33

Divide both sides by 11.

c = 33 / 11

Divide 33 by 11 to get 3.

c = 3 ===> Answer

Solution 1 :-

>> 3k - 8 = 7

>> 3k = 7 + 8

>> 3k = 15

>> k = 15 / 3

>> k = 5

Solution 2 :-

>> 8b + 9 = -15

>> 8b = -15 - 9

>> 8b = -24

>> b = -24 / 8

>> b = -3

Solution 3 :-

>> 8 = 3x - 13

>> 3x = 13 + 8

>> 3x = 21

>> x = 21 / 3

>> x = 7

Solution 4 :-

>> 6p + 22 = 4

>> 6p = 4 - 22

>> 6p = -18

>> p = -18 / 6

>> p = -3

Solution 5 :-

>> 84 = 51 + 11c

>> 11c = 84 - 51

>> 11c = 33

>> c = 33 / 11

>> c = 3

Den pushes a desk 400 cm across the floor. he exerts a force of 10 n for 8 s to move the desk. what is his power output? (power: p = w/t)

Answers

The power output is  = 5W

Correct option is B.

What is Power ?

Power is the quantity of energy that is transferred or transformed in a certain length of time. The unit of power is the watt, which in the International System of Units is equivalent to one joule per second.. Power may also be referred to as activity in earlier writings. The scalar property of power

Power is characterized as the rate at which a thing performs labor.

According to the given information:

P = W/T ..... (1)

Work is calculated as the product of force applied to an item and the distance that object has traveled.

W = F.s

When we plug this value into the equation above, we get:

P = (F. s)/t

where,

power = P =?W

F = 10N Force Exercised

s = Displacement = 400cm = 4m  (1 meter = 100 centimeters).

t = Time required = 8s

Using the values in the equation above, we obtain

P = (10 x 4)/8

P = 5W

Hence, the correct option is Option b.
