A fifth-degree polynomial has three real roots and two imaginary roots.

The given polynomial function f(x) is a fifth-degree polynomial, meaning it has five roots. We are given three of the roots: -2, 2, and 4 + i. Since the coefficients of a polynomial with real coefficients are either real or come in conjugate pairs for complex roots, the remaining two roots must be the complex conjugates of 4 + i, which are 4 - i. Therefore, f(x) has three real roots -2, 2, and 4, and two complex roots 4 + i and 4 - i.

The function f(x), a fifth degree polynomial, has three real roots and two complex (imaginary) roots due to the Conjugate Root Theorem. The roots are –2, 2, 4, 4 + i and 4 - i. Therefore, option D is correct.

The function f(x) is a fifth degree polynomial. Given the roots available, –2, 2, and 4 + i, we already have three roots, two real and one complex (or imaginary). From the Conjugate Root Theorem, which states that if a polynomial has real coefficients, then any imaginary root must have its conjugate as a root. Thus, the conjugate of 4 + i, which is 4 - i, is also a root of this function. Therefore, the fifth degree polynomial has three real roots –2, 2, and 4, and two imaginary roots 4 + i and 4 - i, indicating that option D: 'f(x) has three real roots and two imaginary roots' is correct.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign. For example, 3x – 5 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 7.

There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.

An equation is a mathematical statement that two things are equal. It consists of two expressions, one on each side of an 'equals' sign. For example x=y is an equation where two expressions x and y are equal. Whereas f(x)=x is a function with variable x and hence f(x)=x is not an equation.

Answer:

C. AB/XY = AC/XZ

Step-by-step explanation:

Dilation:

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. The original figure either stretches or shrinks by a certain factor.

In the problem, the dilation is by a factor of 5 and we can see that ABC shrinks to form XYZ.

So, ABC and XYZ are similar triangles which means that the ratio of their corresponding sides will be equal:

AB/XY = AC/XZ = BC/YZ = 5

Answer with explanation:

When ΔABC is dilated by a Scale factor of 5 we will get ΔX Y Z.

Pre-Image = ΔABC

Image = ΔX Y Z

When a triangle is dilated , then the two Triangles that is Original ΔABC and Triangle after dilation ΔX Y Z will be Similar.

The percent of the cash discount being offered is 5%.

The terms 5/10 EOM mean that the customer is eligible for a cash discount of 5% if the invoice is paid within 10 days from the end of the month. In this case, the invoice date is August 1st, so the end of the month is August 31st. To calculate the number of days allowed for the cash discount, we subtract 10 days from August 31st, which gives us August 21st. Therefore, the cash discount is valid until August 21st and the percent of the cash discount being offered is 5%.

For this case we have that by definition, the distance between two points is given by:

Remember that

If two lines are parallel, then their slopes are the same

Line A and Line B have the same slope m=-2 and different y-intercept

therefore

The lines are parallel

Answer:

Second option: Parallel.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope and "b" is the y-intercept.

Solve for "y" in each equation:

Equation 1

[tex]2x=-3-y \\\\2x+y=-3\\\\y=-2x-3[/tex]

Equation 2

[tex]4+y=-2x-2\\\\y=-2x-2-4\\\\y=-2x-6[/tex]

You can notice that the slope of the Equation 1 is:

[tex]m_1=-2[/tex]

And the slope of the Equation 2 is:

[tex]m_2=-2[/tex]

Observe that [tex]m_1=m_2[/tex], then you can conclude that the lines are: Parallel.

Answer:

82 notes

Step-by-step explanation:

3×8=24

16×3=48

4×3=12

24+48+12=84

Final answer:

To find the total number of notes played throughout the song, add the notes from each measure (8 + 16 + 4 = 28) and multiply by the times they are played (28 x 3), resulting in 84 notes played in total.

Explanation:

The question pertains to calculating the total number of notes played in a song where specific measures of music are repeated a certain number of times. First, we need to calculate the number of notes in a single iteration of the three measures:

Measure 1: 8 notes

Measure 2: 16 notes

Measure 3: 4 notes

Adding these together, we get a total of 28 notes for one iteration of the 3 measures. Since these measures are played 3 times throughout the song, we multiply 28 by 3, which equals 84 notes. Therefore, 84 notes are played throughout the song.

Answer:

$[tex]1g[/tex]

Explanation:

If the number of granola bars is represented by the variable [tex]g[/tex], and each granola bar costs $1, then we need to multiply the amount per granola bar by the number of granola bars.

This is $[tex]1 * g[/tex], or $[tex]1g[/tex].

In this scenario, the total cost of the granola bars can be represented by the mathematical expression 'g', as each granola bar costs $1.

If each granola bar costs $1 and 'g' is representing the number of granola bars, then the total cost of the granola bars can be represented by the expression 1 * g or simply g. This is because for every granola bar you buy, you are adding $1 to your total. So if you bought 'g' granola bars, your total cost would be $1 times the number of granola bars 'g'. This is an example of direct proportionality, where the total cost increases with the increase in number of granola bars.

Answer:

sin(B)=cos(90°-B)

Step-by-step explanation:

we know that

In the right triangle of the figure

sin(B)=b/c -----> The sine of angle B is equal to divide the opposite side to angle B by the hypotenuse

cos(A)=b/c -----> The cosine of angle A is equal to divide the adjacent side to angle A by the hypotenuse

we have that

sin(B)=cos(A)

Remember that

A+B=90° -----> by complementary angles

so

A=90°-B

therefore

sin(B)=cos(A)

sin(B)=cos(90°-B)

Answer:

sin(B) = cos(90 -B)

Step-by-step explanation:

In triangle ABC by using angle sum property, ∠A + ∠B + ∠C= 180°

∠A + ∠B + 90°= 180°

∠A + ∠B= 180°-90°

∠A + ∠B = 90°

∠A = 90°- ∠B

sin B = b/a.

cos A = b/a.

Hence, sin B = cos A

put the value of ∠A = 90°- ∠B in cos A

sin (B) = cos (90°-B)

Thus, the correct answer is option (2).

Answer:

9

Step-by-step explanation:

Whatever you do to the denominator, you've got to do to the numerator, and vice versa. So for 8 to become 24, you multiply by 3. do that to the numerator 3 as well. 3 × 3 is 9.

For the sake of showing work I will replace the empty space with an x like so...

[tex]\frac{3}{8} =\frac{x}{24}[/tex]

To find out what x is you must cross multiply (aka butterfly)

***Image of this step is attached below

3*24 = 8*x

72 = 8x

Next divide 8 to both sides to finish isolating x. Since 8 is being multiplied by x, division (the opposite of multiplication) will cancel 8 out (in this case it will make 8 one) from the right side and bring it over to the left side.

72 ÷ 8 = 8x ÷ 8

9 = 1x

9 = x

To make these fractions equivalent the empty spot must be 9

[tex]\frac{3}{8} = \frac{9}{24}[/tex]

The equation of f(x) is  B. F(x) = -√x. Therefore , B. F(x) = -√x is correct.

Here's why:

The parent function of the graph is the square root function, which means the original equation is f(x) = √x.

The graph is reflected across the x-axis.

This means that the y-values are multiplied by -1. In other words, if the original point was (x, √x), the reflected point would be (x, -√x).

Therefore, the equation of the reflected function is f(x) = -√x.

The other options are incorrect because:

A. F(x) = √x is the original equation, not the reflected equation.

C. F(x) = √x - 1 shifts the graph down one unit, but it does not reflect it across the x-axis.

D. F(x) = √x + 1 shifts the graph up one unit, but it does not reflect it across the x-axis.
