The profits of a company are found by subtracting the company's costs from its revenue. If a company's cost can be modeled by 14x + 120,000 and its revenue can be modeled by 40x - 0.0002x^2, what is an expression for the profit?

Answers

Answer 1

The profit function is given by [tex]\( P(x) = -0.0002x^2 + 26x - 120,000 \).[/tex]

To find the expression for the profit, we need to subtract the cost function from the revenue function.

Given:

Cost function: [tex]\( C(x) = 14x + 120,000 \)[/tex]

Revenue function: [tex]\( R(x) = 40x - 0.0002x^2 \)[/tex]

The profit function, ( P(x) ), is given by:

[tex]\[ P(x) = R(x) - C(x) \][/tex]

Substitute the given functions into the profit function:

[tex]\[ P(x) = (40x - 0.0002x^2) - (14x + 120,000) \][/tex]

Now, let's simplify:

[tex]\[ P(x) = 40x - 0.0002x^2 - 14x - 120,000 \][/tex]

[tex]\[ P(x) = 26x - 0.0002x^2 - 120,000 \][/tex]

This is the expression for the profit:

[tex]\[ {P(x) = -0.0002x^2 + 26x - 120,000} \][/tex]

So, the profit function is given by [tex]\( P(x) = -0.0002x^2 + 26x - 120,000 \).[/tex]

It takes to sell A three hours to produce two cells.If you start with cell A,how many cells will you have in 24 hours

Answers

In 24 hours, you will have 48 cells if you start with cell A and keep making cells at the same rate.

If it takes three hours to produce two cells, we can calculate the production rate as follows:

Production rate of A = 2 cells / 3 hours

Now, we want to find out how many cells will be produced in 24 hours:

Number of cells produced in 24 hours = Production rate of A × Number of hours

Number of cells produced in 24 hours = (2 cells / 3 hours) × 24 hours

Number of cells produced in 24 hours = 2 cells/hour × 24 hours

Number of cells produced in 24 hours = 48 cells

Therefore, if you start with cell A and continue producing at the same rate, you will have 48 cells in 24 hours.

An investment grows by 20% over a 20 year period. What is its effective annual percent growth rate?

Answers

Final answer:

The effective annual percent growth rate is 3.97%.

Explanation:

The effective annual percent growth rate can be calculated using the formula:



Effective Annual Growth Rate = (1 + Growth Rate)^(1/n) - 1



Given that the investment grows by 20% over a 20-year period, the growth rate would be 0.20.



Substituting the values into the formula:



Effective Annual Growth Rate = (1 + 0.20)^(1/20) - 1



Simplifying further:



Effective Annual Growth Rate = (1.20)^(0.05) - 1



Effective Annual Growth Rate = 0.0397 or 3.97%

Final answer:

The effective annual percent growth rate for an investment that grows by 20% over a 20-year period is approximately 0.949%.

Explanation:

To calculate the effective annual percent growth rate, we need to use the formula for compound interest:

A = P(1 + r)^n

where:

A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial amount of money).r is the annual interest rate (decimal).n is the number of years the money is invested for.

We can rearrange this formula to solve for r:

r = (A/P)^(1/n) - 1

Given that the investment grows by 20% over 20 years, this means A = 1.20P, as it has increased by 20%. With P as the original amount and n as 20 years, the calculation is:

r = (1.20)^(1/20) - 1

Now we compute the value:

r = (1.20)^(0.05) - 1

r ≈ 0.00949

Converting this into a percentage:

r ≈ 0.949%

Therefore, the effective annual percent growth rate is approximately 0.949%.

Slope is -4/6 or -2/3

Answer:

Slope of the line  12=4x−6y is [tex]\frac{2}{3}[/tex] .

Step-by-step explanation:

The slope line form is denoted by

y = mx + c

Where m is the slope and c is the y- intercept .

As given

The equation of the line is given by .

12=4x−6y

It is also written as

6y = 4x - 12

[tex]y = \frac{4x}{6} -\frac{12}{6}[/tex]

Simplify the above

[tex]y = \frac{2x}{3} -2[/tex]

(Compare with y = mx + c )

Thus

[tex]m = \frac{2}{3}[/tex]

Therefore the slope of the line  12=4x−6y is [tex]\frac{2}{3}[/tex] .

which set of ordered pairs in the form of x y does NOT represent a function of x?

C. {(1, 1.5), (-1, 1.5), (2, 2.5), (-2, 2.5)}
D. {(1, 1.5), (-1, -1.5), (2, 2.5), (-2, 2.5)}

Answers

Answer: Choice B

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

A function is only possible if every x value leads to exactly one y value. Put another way, any input must have exactly one output. With choice B, we have (1,3.3) and (1,4.5). This tells us that the input x = 1 has two outputs y = 3.3 and y = 4.5 at the same time. This is why we do NOT have a function here. 

If we graphed the set of points for choice B, the graph would fail the vertical line test. 

A function is a relationship that maps elements from one set (the inputs) into elements of another set (the outputs). Such that each input can be mapped into only one output.

The correct option is B: {(0, 1.5), (3, 2.5), (1, 3.3), (1, 4.5)}

Using the general definition, to find which set of ordered pairs does not represent a function, we need to see in which set we have the same input (the first element of the ordered pair) assigned to two different outputs (the second element of the ordered pair).

Here the one that does not represent a function is option B:

{(0, 1.5), (3, 2.5), (1, 3.3), (1, 4.5)}

Because we have the input x = 1 assigned to two different outputs, y = 3.3 and y = 4.5

A segment has endpoints with coordinates - 3 and 4. What is the length of the segment?

Answers

Answer: 7 units

Step-by-step explanation: In this problem, the given numbers -3 and 4 represent the coordinates of the endpoints of a segment and we are asked to find the length of the segment.

To find the length of a segment, we take the greater endpoint coordinate minus the lesser endpoint coordinate.

In this case, the greater endpoint coordinate is 4 and the lesser endpoint coordinate is -3.

So, we have 4 - (-3) which can also be thought of as 4 + 3 which equals 7.

Therefore, the length of this segment is 7 units.

What is the relationship between the “solution” to a quadratic equation and the graph of a quadratic equation? How many possible real solutions might there be when you solve a quadratic equation and how do these possible solutions affect the position the parabola on a coordinate plane?

Answers

The solutions of a quadratic equations are the x value of the x-intercepts of the graph. 

If there are 0 real solutions, the parabola will not touch the x-axis.

If there is 1 real solution, the parabola's vertex will be on the x-axis.

If there are 2 real solutions, the parabola will intersect the x-axis in two distinct positions.

Hope this helps!
Final answer:

Solutions of a quadratic equation represent points where the graph of the equation (a parabola) intersects the x-axis, and there could be zero, one, or two real solutions.

Explanation:

The relationship between the 'solution' of a quadratic equation and the graph of a quadratic equation is that the solutions of a quadratic equation correspond to the points where the graph of this equation, also known as a parabola, intersects with the x-axis on a two-dimensional (x-y) graph. A quadratic equation can have zero, one, or two real solutions. These solutions are represented graphically by where the curve of the parabola intersects the x-axis.

When the parabola intersects the x-axis twice, there are two distinct real solutions. If the parabola is tangent to the x-axis, then there is exactly one real solution, also known as a repeated root, whereas if the parabola does not intersect or touch x-axis at all, then there are no real solutions, indicating that the roots are complex or imaginary.

The sum of the squares of two consecutive odd integers is 1570. find the integers

Answers

Let's look at a few examples of two consecutive odd integers.
1, 3
11, 13
55, 57
Notice that the larger integer is always 2 more than the smaller one.

If you let the smaller one be x, then the larger one is x + 2.

Now we square the two numbers.
The square of x is x^2.
The square of x + 2 is (x + 2)^2.

Now we add those two squares and set equal to 1570.

x^2 + (x + 2)^2 = 1570

x^2 + x^2 + 4x + 4 = 1570

2x^2 + 4x + 4 = 1570

2x^2 + 4x - 1566 = 0

x^2 + 2x - 783 = 0

783 is 290 * 27

(x - 27)(x + 29) = 0

x - 27 = 0 or x + 29 = 0

x = 27 or x = -29

Remember that x is the smaller of the two integers.

If x = 27, then x + 2 is 29.
If x = -29, then x + 2 is -27.

The answer is:
There are two pairs of integers
One pair is 27 and 29.
The other pair is -29 and -27.

Final answer:

Two consecutive odd integers whose squares sum to 1570 are found by setting up a quadratic equation. Solving this equation gives us 27 and 29 as the required integers.

Explanation:

The question requires us to find two consecutive odd integers whose squares add up to 1570. Let's consider the smaller integer to be n, which means the next consecutive odd integer would be n + 2 (since there is always a difference of 2 between consecutive odd numbers). Our equation based on the given information will be:

[tex]n^2 + (n + 2)^2[/tex] = 1570

To solve for n, we will expand the equation and simplify:

[tex]n^2 + n^2 + 4n + 4[/tex] = 1570[tex]2n^2 + 4n + 4[/tex] = 1570[tex]2n^2 + 4n - 1566[/tex] = 0Divide the entire equation by 2: n2 + 2n - 783 = 0

Solving the quadratic equation, we find that n = 27 and n = -29.

As we are looking for positive integers, we take n = 27. Therefore, the two consecutive odd integers are 27 and 29.

During the first quarter of the year, 351,875 people downloaded an app for their smartphones. During the second quarter of the year, 101,949 fewer people downloaded the app than during the first quarter. How many downloads occurred during the two quarters of the year?
a. Round each number to the nearest hundred thousand to estimate how many downloads occurred during the first two quarters ofthe year.

Answers

The number of people who downloaded the app in the first quarter is 351,875 people.
Those who downloaded in the second quarter are 101,949 fewer people  than those in first quarter.
This means that:
number of people who downloaded in 2nd quarter = number of people who downloaded in 1st quarter - 101,949
number of people in 2nd quarter = 351,875 - 101,949 = 249,926 people

Therefore, the total number of people who downloaded the app can be calculated as follows:
Total number = 351,875 + 249,926 = 601,801 people

Rounding this number to the nearest hundred thousands, we can get the estimated number of people who downloaded the app as 600,000 people

Find two positive numbers whose product is 36 and whose sum is a minimum.

Answers

Final answer:

To find two positive numbers whose product is 36 and whose sum is a minimum, set up an equation using the arithmetic mean and geometric mean inequality. Solve for the two numbers.

Explanation:

To find two positive numbers whose product is 36 and whose sum is a minimum, we can use the concept of the arithmetic mean and geometric mean inequality. Let the two numbers be x and y. Since the product of the numbers is 36, we have xy = 36. Using the arithmetic mean and geometric mean inequality, we know that the minimum value of the sum of two positive numbers is attained when the two numbers are equal. Therefore, x = y. Substituting this into the equation xy = 36, we have x^2 = 36. Taking the square root of both sides, we get x = √36 = 6. So, the two positive numbers are x = 6 and y = 6.
