One zero of the polynomial is given. Use it to express the polynomial as a product of linear factors over the complex numbers.
Given: f(x) = x^2 + 3x + 3 and zero: 3
Here's how to approach this problem:
The polynomial f(x) has a root of 3.
f(x) can be expressed as a product of two factors, where the first factor contains (x-3) as one of its roots, as follows:
f(x) = (x-3)(ax + b)
We can obtain the values of a and b by equating the coefficients of this equation to that of the given polynomial:
a + 3 = 1 (since coefficient of x in the given polynomial is 3)
-3a + b = 3 (since the constant term in the given polynomial is 3)
Solving these equations gives us a=-2 and b=9.
f(x) can thus be expressed as:
f(x) = (x-3)(-2x + 9)
Hence, the expression for the polynomial is f(x) = -(x-3)(2x-9).

-5 is smaller than -1
-1 is the greatest negative integer.
what is expressed in both units and dollars to show the number necessary to make enough money to keep going?
In the context of economics, the term “break-even point” is used to indicate the number necessary to make enough money to keep going, and it is expressed in both units and dollars.
What is the break-even point?Break-even point is a term used in cost accounting to describe the point at which total cost and total revenue are equal. At this point, there is no profit or loss; it is a neutral zone. At this point, a firm's revenue from the sale of products and services is just sufficient to cover the total costs of producing those products and services.
The break-even point can be expressed in terms of units sold or in terms of total revenue. The point at which the total revenue equals total cost is the break-even point in terms of dollars. The point at which the number of units sold equals the fixed costs divided by the contribution margin per unit is the break-even point in terms of units sold. Therefore, the break-even point is expressed in both units and dollars to show the number necessary to make enough money to keep going.

According to a survey on part-time workers (their monthly salaries can vary by different
months), the average base salary for women is higher than the average base salary for men. The
average base salary for women is $3000/month, and the average base salary for men is
$2750/month. Assume monthly salaries are normally distributed with a standard deviation of $300
for both men and women. Furthermore, assume salaries are independent across different months. How much would a woman have to make in a year to have a higher salary than 99% of her male
counterparts
To have a higher salary than 99% of her male counterparts, a woman would have to make more than $5229.48 per month, or $62753.76 per year
To find out how much a woman would have to make in a year to have a higher salary than 99% of her male counterparts, we need to find the salary level that corresponds to the 99th percentile of the male salary distribution.
First, we need to calculate the standard deviation of the annual salaries for both men and women. Since the standard deviation of the monthly salaries is $300, the standard deviation of the annual salaries can be calculated as:
σ_annual = σ_monthly * √12 = 300 * √12 = $1039.23
Next, we can calculate the salary level that corresponds to the 99th percentile of the male salary distribution using the standard normal distribution table.
z-score for the 99th percentile = 2.33
salary level for the 99th percentile of male salary distribution = mean + z-score * σ_annual
= $2750 + 2.33 * $1039.23 = $5229.48 (rounded to the nearest cent)
Therefore, to have a higher salary than 99% of her male counterparts, a woman would have to make more than $5229.48 per month, or $62753.76 per year (rounded to the nearest cent).

tan t = -4/3
The equation for the unit circle is

For the point (-3/4, y) we have
(-3/4)2 + y2 = 1
Rearranging this gives us
y2 = 1 - (3/4)2
Solving for y gives us
y = √ (1 - (3/4)2)
Now we can find tan t by using the equation
tan t = y / -3/4

The width of a rectangle measures (9. 8g-4. 5h) centimeters, and its length measures (1. 5g-3. 4h) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
The expression that represents the perimeter of the rectangle in centimeters is 45.2g - 30.6h.
Let's start by finding the length of the top and bottom sides, which are equal to the width. The width is given by (9.8g - 4.5h) centimeters, so the length of the top and bottom sides is:
2(width) = 2(9.8g - 4.5h) = 19.6g - 9h
Next, we need to find the length of the left and right sides, which are equal to the length. The length is given by (1.5g - 3.4h) centimeters, so the length of the left and right sides is:
2(length) = 2(1.5g - 3.4h) = 3g - 6.8h
Now that we have the lengths of all four sides, we can find the perimeter of the rectangle by adding them together:
Perimeter = length + width + length + width
Perimeter = (3g - 6.8h) + (19.6g - 9h) + (3g - 6.8h) + (19.6g - 9h)
Perimeter = 45.2g - 30.6h

According to the SAS (Side-Angle-Side) similarity theorem, two triangles are similar if they have two pairs of corresponding sides that are in proportion and the included angles are congruent.
In this example, we know that ΔLKN and ΔKNM share the angle at vertex K, and we also know that LN/MN and LK/KN are in proportion.
To clarify that MN is parallel to LK and forms a transversal with LN, we must first prove that MN/LK||MN.

There will be 8980 illiterate people in Sylvania 4 years from now if the country continues to reduce the number of illiterate citizens by 5 each year.
We can write a function P(t) to represent the number of illiterate people in Sylvania t years from today, where t is the number of years after the current year.
Given that the country has decided to reduce the number of illiterate citizens by 5 each year, we can subtract 5 from the number of illiterate people each year.
The initial number of illiterate people in the country is 9000. So, the function can be written as:
P(t) = 9000 - 5t
where t is the number of years after the current year.
For example, if we want to find out how many illiterate people will be in Sylvania in 4 years from now, we can substitute t with 4:
P(4) = 9000 - 5(4) = 9000 - 20 = 8980

inextensible string passing over a smooth
pulley at the edge of the table to a particle
of mass 2 kg, which is hanging freely. Find the acceleration of the system
and the tension in the string.
5 kg
2 kg
The acceleration of the system is 0.83 m/s² and the tension in the string is 8.3 N.
The acceleration of the system can be calculated using Newton's second law of motion. The equation is F = ma, where F is the net force on the system, m is the total mass, and a is the acceleration. Since the two masses are connected by a light inextensible string, the net force acting on the system is equal to the tension in the string. Therefore, the equation becomes T = (5 kg + 2 kg)a, where T is the tension and a is the acceleration. Solving for a, the acceleration is found to be 0.83 m/s². The tension in the string can also be calculated using the equation above. Plugging in the acceleration, the tension is found to be 8.3 N.

Base on the given data uploaded, 1. Will you conclude that people can bargain price down when purchasing a house at 5% level of significance? 2. Will you conclude that the 3-bedroom houses is cheaper than 4-bedroom houses?
To know whether people can bargain the price down when purchasing a house at a 5% level of significance, we need to put a hypothesis test. The null hypothesis would be that people cannot bargain the price down
To determine whether 3-bedroom houses are cheaper than 4-bedroom houses, we would again give out a hypothesis test. The null hypothesis would be that there is no difference in price between 3-bedroom and 4-bedroom houses.
but the other hypothesis would be that 3-bedroom houses are cheaper than 4-bedroom houses. If the p-value is less than 0.05, we can reject the null hypothesis and say that 3-bedroom houses are more cheaper than 4-bedroom houses.
