Answers

Answer:The zeros are 6, -5, 9

Step-by-step explanation:

The zeros of the polynomial function are x = 6, x = -5, and x = 9. The correct option is A.

What are polynomials?

In mathematics, a polynomial is an expression that solely uses the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables. It is made up of coefficients and indeterminates.

The zeros of the polynomial function are the values of x that make f(x) equal to zero.

The polynomial f(x) is written in factored form as:

f(x) = (x - 6)(x + 5)(x - 9)

The zeros of the polynomial are the values of x that make any of the factors equal to zero. Therefore, the zeros are:

x - 6 = 0, which gives x = 6

x + 5 = 0, which gives x = -5

x - 9 = 0, which gives x = 9

Thus, the zeros of the polynomial function are x = 6, x = -5, and x = 9.

If z is the complex number then IzI = 5 represents the equation of the circle.

What is a circle?

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.

And the general formula of the circle,

(x – h)²+ (y - k)² = r²,

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

Given:

The equation of the circle.

IzI = 5.

The set of all complex numbers with a given modulus (such as 5) always has the shape of a circle.

And the modulus represents the radius of the circle.

Answers

the answer is: 2x sqrt 2x

The expression √(2x²) · √(4x) is equivalent to the expression 2x√2x. Then the correct option is D.

What is an equivalent expression?

The equivalent is the expressions that are in different forms but are equal to the same value.

The expressions are given below.

√(2x²) and √(4x)

Then the product of the expressions √(2x²) and √(4x) will be

⇒ √(2x²) · √(4x)

The factor of 2x² will be

2x² = 2 · x · x

The factor of 4x will be

4x = 2 · 2 · x

Substitute in the expression, then the expression will be

⇒ √(2 · x · x) · √(2 · 2 · x)

We know that √x² = x and √4 = 2. Then the expression will be

⇒ x√2 · 2√x

⇒ 2x√2x

Thus, the expression √(2x²) · √(4x) is equivalent to the expression 2x√2x.

Then the correct option is D.

The measure of an angle is twenty-three times the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer:

∡'s are 172.5° and 7.5°

Step-by-step explanation:

x = 23(180-x)

x = 4140 - 23x

add 23x to each side

24x = 4140

x = 4140/24

x = 172.5

So, supplementary angles is an angle pair that adds up to 180 degrees.

If one of the angles is 23 times larger than the other angle, then the other angle would be 1 times larger, due to the reflexive prop.

So combined, the angle pair is 24 times larger than the small angle. And since we know that the supplementary angle is 180, it's something that easy math can solve.

For the small angle:

180 / 24 --> 7.5 degrees.

Now with the big angle that 23 times that:

7.5 * 23 -->  172.5 degrees.

Tara bought a silver coat rack originally priced at $375 but on sale for 20% off. After 12% sales tax, what was the total cost?

Answers

Answer:

$336

Step-by-step explanation:

1 - 20% = .8

1 * 12% = 1.12

375 * .8 * 1.12 = 336

The total cost was of $336.

--------------

This question is solved using percentages/proportions.

The original price is of $375.On sale for 20% off, which means that you pay 1 - 0.2 = 0.8 of the price.Sales tax of 12%, which means that the cost is also multiplied by 1 + 0.12 = 1.12.

Thus, the total cost will be given by:

[tex]C = 375 \times 0.8 \times 1.12 = 336[/tex]

The total cost was of $336.

  (months, dollars) = (1, 675)  and  (4, 600)

Using the slope formula, we have ...

A nutritionist suspected that her company's clients had below average cholesterol. They obtained a random sample of 8 clients of the same age and gender. These clients had a mean cholesterol level of xˉ=4.28 mmol/L (millimoles per liter).
To see how likely a sample like this was to happen by random chance alone, the nutritionist performed a simulation. They simulated 60 samples of n=8 cholesterol levels from a normal population with a mean of 4.6 mmol/L and a standard deviation of 0.5 mmol/L (these are generally accepted values for people with the same age and gender of those in the sample). They recorded the mean of the cholesterol levels in each sample. Here are the sample means from their 60 samples:

They want to test H0:μ=4.6 mmol/L vs. Ha:μ<4.6 mmol/L where μ is the mean cholesterol level for all clients like those sampled.

Based on these simulated results, what is the approximate p-value of the test?
Note: The sample result was xˉ=4.28 mmol/L.

Can someone please help me? Before you ever buy your first stock or bond, it's important to understand what type of investor you are. This depends on a number of factors, including your investment objectives, your time horizon, your tolerance for risk, your personal investment experience, and your overall financial situation. There are three general categories of investors: The conservative investor values protecting principal over seeking capital appreciation. This investor is comfortable accepting lower returns for a higher degree of stability and/or liquidity. The conservative investor wants to minimize risk and loss of principal. The moderate investor values reducing risks and enhancing returns equally. This investor is willing to accept modest risks to seek higher long-term returns. A moderate investor may endure short-term loss of principal and a lower degree of liquidity in exchange for long-term capital appreciation. The aggressive investor values maximizing returns and is willing to accept substantial risk. This investor believes that maximizing long-term returns is more important than protecting principal in the short term and understands that this may mean enduring volatility and significant losses. Liquidity generally isn't a consideration for the aggressive investor. Which of these categories best describes you? Which of the following did Shi Huangdi do in order to control Chinese thought? A.
