The company's advanced degree holders make up 18% of the workforce.
A percentage is what?A percentage, which is denoted by the number 100, is a proportion, fraction, or piece of a whole. The Roman phrase per centum, which meaning "by the 100" or "per one hundred," is where the term "percent" originates. A numerical value and the percentage symbol (%) can be used to express percentages.
Part A:
The following expression sums up the amount of company employees with advanced degrees:
0.40c(0.15) + 0.60c(0.20)
Explanation: First, we multiply the overall amount of workers (c) by the proportions of male and female employees, which are, respectively, 40% and 60%. The number of male workers (0.40c) is then multiplied by the percentage of men who have advanced degrees (15%), and the number for female employees (0.60c) is multiplied by the percentage of women who have advanced degrees (20%). In order to calculate the overall number of workers with advanced degrees, we must add these two numbers.
If we condense this phrase, we get:
0.06c + 0.12c = 0.18c
Part B:
The number of staff members with advanced degrees must be divided by the total amount of employees, and the result must be multiplied by 100% to determine the percentage of the business that holds advanced degrees:
(0.18c/c) × 100% = 18%
Therefore, 18% of the company has advanced degrees.

Find a 5th degree polynomial with real coefficients that has zeros 0, -7i, and 2-i. show work
Answer:
f(x) = x^5 - 4x^4 + 54x^3 - 196x^2 + 245x.
Step-by-step explanation:
If a polynomial has a complex root, then its conjugate is also a root. Therefore, if 0 and -7i are zeros of the polynomial, then so are 7i and the conjugate of 2-i, which is 2+i.
The factors of the polynomial are then:
(x-0)(x-7i)(x+7i)(x-(2-i))(x-(2+i))
Simplifying the factors, we get:
x(x^2+49)(x^2-4x+5)
Expanding the last factor, we get:
x^5 - 4x^4 + 5x^3 + 49x^3 - 196x^2 + 245x
Finally, we have the 5th degree polynomial:
f(x) = x^5 - 4x^4 + 54x^3 - 196x^2 + 245x
Therefore, the polynomial with zeros 0, -7i, and 2-i and 5th degree with real coefficients is f(x) = x^5 - 4x^4 + 54x^3 - 196x^2 + 245x.
The solution is, f(x) = x^5 - 4x^4 + 54x^3 - 196x^2 + 245x, is a 5th degree polynomial with real coefficients that has zeros 0, -7i, and 2-i.
What are Polynomials?Polynomials are sums of k-xⁿ terms, where k can be any number and n can be any positive integer.

A certain airline requires that rectangular packages carried on an airplane by passengers be such that the sum of the three dimensions is at most 270 centimeters. Find the dimensions of the square-ended rectangular package of greatest volume that meets this requirement.
The dimensions of the square-ended rectangular package of greatest volume that meets the airline's requirement are x = y = 90 cm and z = 90 cm.
What is dimensions?Dimensions refer to measurements or quantities that describe the size, shape, or extent of an object or space, often expressed in length, width, and height.
Let x, y, and z represent the dimensions of the rectangular package. Since the package has square ends, we know that x = y.
We want to maximize the volume of the package, which is given by V = x² × z.
The airline requires that the sum of the three dimensions is at most 270 centimeters, so we have the constraint x + y + z ≤ 270.
Substituting x = y, we get 2x + z ≤ 270.
We can solve for z in terms of x: z ≤ 270 - 2x.
Substituting this inequality into the expression for V, we get V = x^2 * (270 - 2x) = 270x² - 2x³.
To maximize V, we take the derivative of V with respect to x, set it equal to zero, and solve for x:
dV/dx = 540x - 6x² = 0
6x(90 - x) = 0
x = 0 or x = 90
Since x represents a length, it must be positive, so x = 90.
Since x = y, y = 90 as well.
Substituting x = y = 90 into the inequality z ≤ 270 - 2x, we get z ≤ 270 - 2(90) = 90.

f(0) = -4.
How to obtain the numeric value of a function or of an expression?To obtain the numeric value of a function or of an expression, we substitute each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.
The function for this problem is defined as follows:
f(x) = 3x² - 7x - 4
We want to find the numeric value of the function at x = 0, hence both instances of x in the definition of the function are replaced by zero and then we add the terms, as follows:
f(0) = 3(0)² - 7(0) - 4
f(0) = -4.

Thus, the length of the missing side for the given Right triangles using the Trigonometric Ratios is found as :x = 18.47 units.
What is meant by Trigonometric Ratios?In order to examine the sides of both a right triangle, which will depend on an acute angle, trigonometric ratios are used. Right triangles what about those produced by the intersection of the legs, which have an internal angle of 90 degrees. We can determine the right triangle's missing sides or sharp angles using trigonometric ratios.The leg, denoted as, that is next to the 30 degree angle θ is represented by Side BC. To get the length of side BD, the hypotenuse of triangle BCD, we use the cosine ratio.
cos θ = Adjacent leg / Hypotenuse = BC/BD
cos 30° = 8√2 / BD
Now, we know.
cos 30° = √3/2
√3/2 = 8√2 / BD
BD = 8√2 / √3/2
BD = 16√2 / √3
On rationalising;
BD = 16√2*√3 / √3*√3
BD = 16√6 / 3
Sin A = Opposite leg /Hypotenuse = BD / x
Sin 45° = (16√6 / 3) / x = 16√6 / 3x
We know that:
Sin 45° = 1/√2
(1/√2) = 16√6 / 3x
(1/√2) * x = 16√6 /3
Or,
√2/2 * x = (16√6 /3) * (2/√2)

Find all critical points for the function

on (-∞, ∞) and then list them (separated by commas) in the box below.
List of critical points:
f(x) =
Answer: [tex]\frac{-3+\sqrt{7}}{2}, \ \frac{-3-\sqrt{7}}{2}[/tex]
========================================================
Explanation:
Let
g(x) = 4x+6h(x) = x^2+x+1Each derivative is,
g ' (x) = 4h ' (x) = 2x+1which will be useful in the next section.
--------------
[tex]f(\text{x}) = \frac{4\text{x}+6}{\text{x}^2+\text{x}+1} = \frac{g(\text{x})}{h(\text{x})}\\\\f(\text{x}) = \frac{g(\text{x})}{h(\text{x})}\\\\[/tex]
Apply the derivative with respect to x. We'll use the quotient rule.
[tex]f(\text{x}) = \frac{g(\text{x})}{h(\text{x})}\\\\\\f'(\text{x}) = \frac{g'(\text{x})h(\text{x})-g(\text{x})h'(\text{x})}{\big[h(\text{x})\big]^2}\\\\\\f'(\text{x}) = \frac{4(\text{x}^2+\text{x}+1)-(4\text{x}+6)(2\text{x}+1)}{(\text{x}^2+\text{x}+1)^2}\\\\[/tex]
The critical value(s) occur when either...
f ' (x) = 0f ' (x) doesn't exist, when x is in the domain of f(x)The first criteria will be handled in the next section.
The second criteria is handled in the section after that.
-------------------------
f ' (x) is in the format A/B. It means f ' (x) = 0 leads to A/B = 0 and A = 0.
We set the numerator equal to zero and solve for x.
[tex]4(\text{x}^2+\text{x}+1)-(4\text{x}+6)(2\text{x}+1) = 0\\\\4(\text{x}^2+\text{x}+1)-(8\text{x}^2+16\text{x}+6) = 0\\\\4\text{x}^2+4\text{x}+4-8\text{x}^2-16\text{x}-6 = 0\\\\-4\text{x}^2-12\text{x}-2 = 0\\\\-2(2\text{x}^2+6\text{x}+1) = 0\\\\2\text{x}^2+6\text{x}+1 = 0\\\\[/tex]
From here we use the quadratic formula.
Plug in a = 2, b = 6, c = 1.
[tex]\text{x} = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\\text{x} = \frac{-6\pm\sqrt{(6)^2-4(2)(1)}}{2(2)}\\\\\text{x} = \frac{-6\pm\sqrt{28}}{4}\\\\\text{x} = \frac{-6\pm2\sqrt{7}}{4}\\\\\text{x} = \frac{2(-3\pm\sqrt{7})}{4}\\\\\text{x} = \frac{-3\pm\sqrt{7}}{2}\\\\\text{x} = \frac{-3+\sqrt{7}}{2} \text{ or } \text{x} = \frac{-3-\sqrt{7}}{2}\\\\[/tex]
If x is equal to either of those values, then f ' (x) = 0 would be the case. Therefore, these are the critical points of f(x).
There may be other critical values. We'll still need to check the second criteria.
-------------------------
f ' (x) doesn't exist when we divide by zero.
Set the denominator equal to 0 and solve for x.
[tex](\text{x}^2+\text{x}+1)^2 = 0\\\\\text{x}^2+\text{x}+1 = 0\\\\[/tex]
Plug a = 1, b = 1, c = 1 into the quadratic formula.
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-1\pm\sqrt{(1)^2-4(1)(1)}}{2(1)}\\\\x = \frac{-1\pm\sqrt{-3}}{2}\\\\[/tex]
We have a negative number as the discriminant, which leads to complex number solutions in the form a+bi where [tex]i = \sqrt{-1}[/tex]
Therefore, there aren't any real number values for x that lead [tex](\text{x}^2+\text{x}+1)^2[/tex] to be zero.
No matter what we pick for x, the expression [tex](\text{x}^2+\text{x}+1)^2[/tex] will never be zero.
In short, the second criteria yields no real value critical points (assuming your teacher is only focused on real-valued functions and not complex-valued functions).
-------------------------
Summary:
The first criteria f ' (x) = 0 led to [tex]\text{x} = \frac{-3+\sqrt{7}}{2} \text{ or } \text{x} = \frac{-3-\sqrt{7}}{2}[/tex] as the critical valuesThe second criteria, f ' (x) doesn't exist where x is in the domain of f(x), leads to no critical values (assuming your teacher is not focusing on complex-valued functions).Therefore, the only critical values are [tex]\text{x} = \frac{-3+\sqrt{7}}{2} \text{ or } \text{x} = \frac{-3-\sqrt{7}}{2}[/tex]
-------------------------
Extra info:
A critical value is where a local/absolute min, a local/absolute max, or a saddle point would be at this x value. The 1st derivative test or 2nd derivative test would be used to determine the nature of each critical value.
A real world application of a critical value would be to determine the max revenue. Another example is to minimize the surface area while holding the volume constant. Linear regression relies on a similar concept.

The value of the 5 measurements according to the given function is 66.
What is summation of values?When a group of numbers, known as addends or summands, are added together in mathematics, the outcome is their sum or total. Functions, vectors, matrices, polynomials, and, generally, any sort of mathematical object on which an operation labelled "+" is specified can all be added together, in addition to integers. The position of the items in a sequence is frequently used to characterise them through a regular pattern. Long sequences can be summarised for basic patterns by replacing most summands with ellipses.
The function is given as:
[tex]\sum_{i = 1}^5 (x_i^2)\\\\\sum_{i = 1}^5 = x_1 + x_2 + x_3 +x_4 + x_5\\\\\sum_{i = 1}^5 (x_i^2) = 12 + 14 + 16 + 7 + 17 = 66[/tex]
Hence, the value of the 5 measurements according to the given function is 66.

Find a formula for the linear function depicted in the following graph.
The equation of the line passing through the points (0, 7) and (2, -5) is y = -6x + 7
What is an equation?An equation is an expression that shows how two or more numbers and variables are related using mathematical operations of addition, subtraction, multiplication, division, exponents and so on.
The standard form of a linear equation is:
y = mx + b
where m is the slope(rate of change) and b is the y intercept
As shown in the graph, the line passes through the points (0, 7) and (2, -5). Hence:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\substituting:\\\\y-7=\frac{-5-7}{2-0} (x-0)\\\\y=-6x+7[/tex]
The equation of the line is y = -6x + 7

find the domain of the function f(x)=7x+5/3x-1
The domain of the function f(x)=7x+5/3x-1 is all real numbers except x = 1/3. This means that the function will produce a real number for any value of x except for x = 1/3.
What is a function?Function in mathematics is a relation which assigns each element of a set (called the domain) to exactly one element of another set (called the codomain). It can also be thought of as a type of mapping from one set to another. Functions are used to model real-world problems and to simplify the expression of a certain problem. They are widely used in algebra, trigonometry and other areas of mathematics.
The domain of a function is the set of all possible inputs for the function. In other to determine the domain of a function, we must first identify the independent variable (x) and then determine which values of x can be used in the function.
In the given function, f(x)=7x+5/3x-1, the independent variable is x. To find the domain of this function, we must identify the values of x that will produce results that are real numbers. To do this, we must set the denominator (3x-1) equal to zero and solve for x.
We can solve this equation by factoring and setting each factor equal to zero:
3x - 1 = 0
3x = 1
x = 1/3
Therefore, the domain of the function f(x)=7x+5/3x-1 is all real numbers except x = 1/3. This means that the function will produce a real number for any value of x except for x = 1/3.

Answer:
The number of hamburgers is 136.
Step-by-step explanation:
What we know:
We got cheeseburgers and hamburgers
The total: 408
The number of cheese burgers was 2 times the number of hamburgers
This is pretty much all the info we need to know.
Lets define our variables:
x = hamburgers
y = cheeseburgers
Now, we need our two equations to make a system.
[tex]x+y=408[/tex]
[tex]y=2x[/tex]
To find hamburgers, x, we plug the value of y into our first equation.
[tex]x+2x=408[/tex]
Add like terms
[tex]3x=408[/tex]
Divide by 3
[tex]x=136[/tex]
The number of hamburgers is 136.
Just to check our work, lets find the cheeseburgers.
[tex]y=2(136)[/tex]
[tex]y=272[/tex]
[tex]272+136=408[/tex]

What kind of transformation converts the graph of f(x)=2|x|+4 into the graph of g(x)=|x|+2?
reflection across the y-axis
reflection across the x-axis
Vertical stretch
Vertical Shrink
Answer:
The transformation that converts the graph of f(x)=2|x|+4 into the graph of g(x)=|x|+2 is a Vertical Shrink.
To see this, note that the 2 in f(x) causes a vertical stretch of the absolute value graph. Removing the 2 in g(x) results in a Vertical Shrink of the absolute value graph. The +4 and +2 only cause a vertical shift of the graph.
Answer: Vertical Shrink
Step-by-step explanation:
The transformation that converts the graph of f(x)=2|x|+4 into the graph of g(x)=|x|+2 is a vertical shrink.
To see why, let's examine each function separately:
The function f(x) = 2|x| + 4 has an absolute value in its equation, which means it has a "V" shape. The coefficient 2 in front of the absolute value means that the "V" is stretched vertically by a factor of 2. The constant 4 added to the end of the function moves the entire graph up by 4 units.The function g(x) = |x| + 2 also has an absolute value in its equation, but without a coefficient in front of it. This means that the "V" shape is not stretched or shrunk vertically. The constant 2 added to the end of the function moves the entire graph up by 2 units.Therefore, the transformation from f(x) to g(x) involves removing the vertical stretch by dividing the absolute value term by 2. This results in a smaller "V" shape for the graph of g(x), or a vertical shrink.
The answer is:
[tex]$\boxed{\text{Vertical Shrink}}$[/tex]
