For the function f(x) = -3x+8, determine f(-4).

Answers

Answer 1

Answer:

[tex]{ \tt{f(x) = - 3x + 8}} \\ \\ { \tt{f( - 4) = - 3( - 4) + 8}} \\ \\ { \tt{f( - 4) = 12 + 8}} \\ \\ { \tt{f( - 4) = 20}}[/tex]

Answer 2

For the function f(x) = -3x + 8, f(-4) is 20.

Given,  f(x) = -3x + 8 and f(-4)

Put the value -4, wherever x is present,

f(x) = -3x + 8

f(-4) = (-3 × -4) + 8

f(-4) = 12 + 8

f(-4) = 20

∴ The value of f(-4) is 20 for function f(x) = -3x + 8

This function connects an input to an output. "f(x) = ..." is the classic way to write a function. We will see different ways of thinking about functions, but there are always three main parts: input, relation, and output.

Answers

The maximum profit which this company can expect to earn is $11,650.

What is the maximum value of a function?

The maximum value of a function can be defined as a point on the graph where the function reaches its highest point. This ultimately implies that, the maximum value of a function simply refers to its vertex on a graph.

In order to determine the maximum profit which this company can expect to earn, we would differentiate the given function as follows:

f(x) = y = -10x² + 700x - 600

y' = -20x + 700

-20x + 700 = 0

20x = 700

x = 700/20

x = 35.

Substituting the parameter into the formula, we have;

f(x) = -10x² + 700x - 600

f(35) = -10(35)² + 700(35) - 600

f(35) = -12250 + 24,500 - 600

f(35) = $11,650.

After solving percent equation ,the number of red pins from the set of red and yellow pins that Pam ordered is 910 red pins out of 1000 pins.

What is percent equation?

Eventually, we'll run into a problem that requires us to calculate a percentage of something. The percent equation is the formula we'll employ and it goes like this: part = percent x whole.

The symbol for percent (%) denotes a percentage of one hundred.

You'll need to convert between a percent and a decimal to express these numbers, so let's take a moment to go over that. When you see a percentage, it means 40 out of 100, or 40/100, and that is our fraction. When you divide 40 by 100, you get the decimal 0.40. Remember that 0.40 is the same as 40/100, which means 40%, when converting a decimal to a percent.

Pam ordered a set of red and yellow pins. She received 1,000 pins, and 91% of them were red, so the amount of red pins is

red pins = 91/100  ×  1000

red pins = 910

Thus, the number of red pins from the set of red and yellow pins that Pam ordered is 910 red pins out of 1000 pins

Graph each equation by using the x and y intercepts
Question 2: 5x-2y=7

Answers

The x and y intercepts are (7/5, 0) and (0, -7/2) respectively.

What are x and y intercepts?A line crosses the x-axis at the x-intercept, and the y-intercept is where the line crosses the y-axis.We can graph linear equations by considering intercepts.Since the x-intercept lies on the horizontal axis, it is also known as the horizontal intercept.Since the y-intercept lies on the vertical axis, it is also referred to as the vertical intercept.

Given equation is 5x-2y = 7.

To find the x-intercept substitute y = 0 in the equation and then solve,

5x - 0 = 7

x = 7/5

So the x-intercept is (7/5, 0).

Similarly, to find the y-intercept substitute x = 0 in the equation and then solve,

0 - 2y = 7

y = -7/2

So the y-intercept is (0, -7/2).

Now, graph the intersections of (7/5, 0) and (0, -7/2).

A law firm is going to designate associates and partners to a big new case. The daily rate charged to the client for each associate is $800 and the daily rate for each partner is $1800. The law firm designated twice as many partners as associates to the case and was able to charge the client $17600 per day for these lawyers' services. Write a system of equations that could be used to determine the number of associates assigned to the case and the number of partners assigned to the case. Define the variables that you use to write the system.

Answers

The daily rate charged to the client for each associate is $800 and the daily rate for each partner is $1800.  The equations that could be used to determine the number of associates assigned to the case and the number of partners assigned to the case is: 800 x + 1800 y = 17600.

Equation

Let variable x = number of associates, assigned to the case

Let variable y = number of partners assigned to the case.

The system of equations to describe this are:

800 x + 1800 y = 17600

y = x + 2

Plugging equation 2 in equation 1, we get,

800 x + 1800(x+ 2) = 17600

2600 x + 3600 = 17,600

Collect like terms

2400 x = 14,000

Divide both side by 2400x

x = 14,000 / 2400

x = 5.8

x = 6 (Approximately)

So,

y = x + 2

y = 5.8 +3

y = 7.8

y = 8 (Approximately)

Therefore the number of associates assigned to the case were 6, and the number of partners associated to the case were 8.

Answers

There are 6 customers in the barber shop on an average.

What is average in ?

In mathematics, the middle value—which is determined by dividing the sum of all the values by the total number of values—is the average value in a set of numbers. To calculate the average of a set of data, add up all the values and divide the result by the total number of values.

As per the Little's law, the average number of costumers or individuals in a system (L) can be calculated by multiplying the average arrival rate (λ) and the average time each customer spends in the system (W).

The algebraic expression, is as follows:

L = λW

Here,

L=inventory or average number of customers in the system.

λ=arrival rate = 10

W=flow time average customer spends in the system = 0.6

L = 0.6 * 10 = 6

So, We get;

For 0 months, balance is $1,700.
