Profit is the money you have left after paying for business expenses.

What is profit?Profit is the term used to describe the monetary gain experienced when the revenue from a business activity outpaces the costs, costs, and taxes incurred to maintain the activity in question.Any earnings go back to the company's owners, who can choose to keep the money for themselves, give it to shareholders as dividends, or put it to use again in the company.A business's profit is the money left over after all costs have been deducted. Any business, whether it be a lemonade stand or a publicly traded multinational corporation, has as its main objective making money. As a result, a business's success is measured by its profitability in all of its forms.Depending on the analyst, profitability before taxes and other expenses may be more important to them than top-line profitability. Others are only interested in profitability after expenses have been covered.

The production of the products are given below with the profit as well:

a. Production of Product 1 = 50 units per week

b. Production of Product 2 = 0 units per week

c. Production of Product 3 = 145 units per week

d. Production of Product 4 = 10 units per week

A scatter plot shows data points that are widely scattered around a line that slopes down to the right. Which of the following values would be closest to the correlation for these data? a. -0.40 b. -0.80 c.0.40 d. 0.80

Answers

a value of -0.40 would indicate a moderate negative correlation.

The correlation for a scatter plot describes the strength and direction of the linear relationship between two variables. A negative correlation means that as one variable increases, the other variable decreases, and a positive correlation means that as one variable increases, the other variable also increases.

If the data points in the scatter plot are widely scattered around a line that slopes down to the right, this indicates a negative correlation between the two variables. In this case, the value that would be closest to the correlation would be a. -0.40. This is because the correlation values range from -1 to 1, with -1 indicating a strong negative correlation and +1 indicating a strong positive correlation.

x = 5pi /3 + 2 pi n                      

Step-by-step explanation:

8 cos^2 x + 4 cos x-4 = 0

Divide by 4

2 cos^2 x +  cos x-1 = 0

Let u = cos x

2 u^2 +u -1 =0

Factor

(2u -1) ( u+1) = 0

Using the zero product property

2u-1 =0    u+1 =0

u = 1/2      u = -1

Substitute cosx for u

cos x = 1/2    cos x = -1

Take the inverse cos on each side

cos ^-1(cos x) = cos ^-1(1/2)   cos ^-1( cos x) =cos ^-1( -1)

x = pi/2 + 2 pi n                            x = pi + 2 pi n   where n is an integer

what is the y-intercept of the function f(x) = -2/9x + 1/3 = ?

Answers

Answer:

y - intercept = 1/3

Step-by-step explanation:

to find y - intercept of a function set x = 0

by substituting x = 0 in the function,

f(0) = -2/9(0) + 1/3 = 1/3

thus, y - intercept of the given function is 1/3

The y-intercept of the function f(x) = -2/9x + 1/3 is 1/3.

To find the y-intercept of a given function, set x = 0 and solve for y.

we have a function f(x) = -2/9x + 1/3, substitute x = 0:

f(0) = -2/9(0) + 1/3

= 0 + 1/3

= 1/3

So, the y-intercept of a given function f(x) = -2/9x + 1/3 is 1/3.

Answers

The average number of hours that adults spend working each day is 8 hours and Ryan is correct because he got the average of 8 right.

We know that,

The sample mean is a statistic that is computed by taking the arithmetic mean of the values of a variable in a sample. If the sample is taken from probability distributions with a shared expected value, the sample mean is an estimator of that value.

The mean is gotten from the formula;

x' = ∑x/n

Number of hours of work per day are; 6, 7, 8, 9 and 10

Thus; sum up all of it

∑x = 6 + 7 + 8 + 9 + 10

∑x = 40

Mean is; x' = 40/5

x' = 8

Since Ryan concluded that the average is 8 hours,

(a) Find the angular speed of the fan in radians per minute.
(b) Find the number of revolutions a blade makes per minute.

Answers

(a)  Angular speed of the fan = 360 radians/min.

(b) Number of revolutions = 57 revolutions/min.

What is defined as the angular speed?The angular speed of an object is the rate at which it rotates over time. The mathematical form is the change in an object's central angle with respect to time. It computes the distance or number of revolutions an entity travels during its rotation over time.The rate of change of angular displacement is defined as angular speed, and it is expressed as: = t. is the angular displacement, and t is the time.

The relation between the linear speed ans the angular speed is;

v = rω

Where, v is the linear speed, r is the radius and ω is the angular speed.

Part a: Linear speed of fan = 8 feet per second

Convert it in inch/min.

8 feet /second × 12 inches × 60 sec

5760 inch/min

Radius of the blades of fan; 16 inches.

Put the values;

v = rω

v/r = ω

ω = 5760 inch/min /(16 inches)

ω = 360 radians/min

Thus, the angular speed of the fan is found as 360 radians/min.

Part b: For number of revolutions a blade.

ω = 360 radians/min × (1 revolution/2π radians)

ω = 57.29 revolutions/ min

ω = 57 revolutions/ min (approx)

Thus, the revolution of the fan is found as ω = 57 revolutions/ min (approx).

identify an equation in slope-intercept form for the line parallel to y=1/4x-7 that passes through (-2,-6)

identify an equation in slope-intercept form for the line parallel to y=1/4x-7 that passes through (-2,-6)

Answers

Answer:

D. \(y + 6 =- \frac{1}{4} (x+2)\)

Step-by-step explanation:

We are given that a line is parallel to the line y=-1/4x-7 and passes through (-2, -6).

We want to write the equation of this line.

First, we need to know that parallel lines have the same slope.

In y=-1/4x-7, the slope of the line is -1/4; it is also the slope of the line parallel to it.

All of the answers in your system are written in point-slope form, which is \(y-y_1=m(x-x_1)\), where m is the slope and \((x_1, y_1)\) is a point

As we already know the slope and the point, we can plug these values into the formula.

Starting with the slope; as found above, the slope is -1/4. Therefore, the equation will then be:

\(y-y_1=-\frac{1}{4} (x-x_1)\)

Now substitute -2 and -6 as \(x_1\) and \(y_1\) respectively (note: we have NEGATIVE numbers, and SUBTRACTION in the formula, so we will end up subtracting a negative).

\(y--6=-\frac{1}{4} (x--2)\)

We can simplify this to become:

\(y+6=-\frac{1}{4} (x+2)\)

Therefore, D is the answer.

Answers

The system described above is nonlinear because it contains a term with y(t) multiplied by t. The Laplace transform of f(t) is (6/s²)+(1/s).

If we substitute y1(t) and y2(t) into the equation and add them together, we get:

dy1/dt + 3 + 3ty1(t) = 1² f(t) dt dy2/dt + 3 + 3ty2(t) = 1² f(t) dt

Then we can add these two equations together to get:

d(y1+y2)/dt + 3 + 3t*(y1+y2)(t) = 2*1² f(t) dt

This is not equal to the original equation with y(t), which means that the system is nonlinear.

To find the Laplace transform of f(t), we can use the formula:

L{f(at+b)} = (1/a) ×F(s-b/a)

where F(s) is the Laplace transform of f(t). In this case, we have:

f(t) = (1+6t)

So we can rewrite this as:

f(t) = (6×t+1)

Now we can use the formula to find the Laplace transform:

L{(6×t+1)} = (6/s²)+(1/s)

Therefore, the Laplace transform of f(t) is (6/s²)+(1/s).

(e) 60 hundreds = 6,000 :- True

Consider the first statement,

45 tens are equal to 450

So, 45 tens mean 45 times 10 is written as:

45 × 10 = 450

Hence, it's true.

Consider the second statement,

12.3 is equal to 123 ones.

Now, 123 ones is equal to 123 times 1.

123 × 1 = 123

Hence, the statement is true.

Consider the third statement,

80 tens is greater than 6 hundreds.

Now 80 tens = 80 × 10 = 800

Now, 6 hundreds = 6 × 100 = 600

Now, 800 > 600

Hence, the statement is true.

Consider the fourth statement.

43,200 is less than 50 thousands.

e. 2|x-4|-3y³ when x=3 and y=-2

Answers

Answer:

26

Step-by-step explanation:

To find the value of the expression 2|x-4|-3y³ when x=3 and y=-2, we need to substitute the values of x and y into the expression and then simplify. The absolute value part of the expression, |x-4|, is the distance between the number x and 4 on the number line. When x=3, this distance is |3-4|=1. So the expression becomes 2*1-3(-2)³ = 2-3(-8) = 2+24 = 26. Therefore, when x=3 and y=-2, the value of the expression 2|x-4|-3y³ is 26.
