The rate at which her daily revenue is currently changing and the direction of the change is; Her revenue is currently increasing at $12 per day

The rate of change of a function is the rate at which the output of the function changes per unit change in the input of the function.

Let x represent the number of days, therefore;

The number of T-shirts Dorothy sells, y = 40 - 4·x

The price at which she sells the T-shirts = 7 + x

Therefore, Dorothy's daily revenue, R(x) = (40 - 4·x) × (7 + x) = 12·x - 4·x² + 280

The rate of change of her daily revenue can be obtained from the derivative of the revenue function as follows;

The rate at which her daily revenue is therefore;

R'(x) = d(R(x))/dx = 12 - 8·x

The rate at which her revenue is changing currently can be obtained from the rate function by plugging in x = 0, as follows;

R'(0) = 12 - 8×0 = 12

Her revenue is changing at a rate of $+12 per day.

The positive value of the rate, 12, indicates that her revenue is increasing at $12 per day

The population of Westville increased by approximately 99.95 people from 2015 to 2016.

To find the increase in population from 2015 to 2016 in Westville, we need to use the formula:

Increase in population = (Population density in 2016 - Population density in 2015) x Land area

First, we need to find the population density in 2016. To do that, we can divide the population of 2,000 people by the land area of 84.4 square miles:

Population density in 2016 = 2,000/84.4 ≈ 23.69 people per square mile

Next, we can plug in the values into the formula:

Increase in population = (23.69 - 22.5) x 84.4 ≈ 99.95 people

Answer:

(7x² / 6x - 10)

Step-by-step explanation:

To divide rational expressions, we flip the second fraction (the divisor) and multiply it with the first fraction (the dividend). Then we simplify the resulting expression, if possible.

So,

(7x² /2x +6) ÷ (3x -5/ x+3)

= (7x² /2x +6) * (x+3/3x -5)

= 7x²(x+3) / 2(x+3)(3x -5)

= 7x² / 6x - 10

Therefore, the quotient of the given rational expressions is (7x² / 6x - 10), which cannot be further reduced.

Answer:

B is the correct answer

Step-by-step explanation:

The general form of the equation for a circle centered at the origin (0, 0) is x^2 + y^2 = r^2, where r is the radius of the circle. The radius can be calculated as the distance between the center O (0, 0) and point B (4, 5) on its circumference using the distance formula: r = sqrt((x2 - x1)^2 + (y2 - y1)^2) = sqrt((4 - 0)^2 + (5 - 0)^2) = sqrt(16 + 25) = sqrt(41). Therefore, the equation for the given circle centered at O (0, 0) is x^2 + y^2 = 41. The correct answer is B. x^2 + y^2 − 41 = 0.

Step-by-step explanation:

To find the result when the number 59 is decreased by 3.9%, we need to first calculate what 3.9% of 59 is.

To do this, we can multiply 59 by 3.9% (or 0.039), which gives us:

59 x 0.039 = 2.301

This tells us that 3.9% of 59 is 2.301.

Next, we need to subtract 2.301 from 59 to get the final result:

59 - 2.301 = 56.699

Therefore, the result when the number 59 is decreased by 3.9% is 56.699.  we could say that if you take 3.9% of 59 and subtract that amount from 59, the answer is 56.699.

B. They connect two endpoints

Both statements A and B are true about line segments. Line segments are one-dimensional figures that have two endpoints and connect them with a straight path.

Statement C is not true. Line segments do not have a unit of measure on their own, but their length can be measured using a unit of measure such as inches, centimeters, or meters.

Statement D is not true either. Line segments are flat, one-dimensional objects and cannot grow to become three-dimensional objects. However, multiple line segments can be connected to form a three-dimensional object, such as a cube or pyramid.

Here, we want to get the final volume

From the general gas equation, we have it that:

[tex]\dfrac{P_1V_1}{T_1} =\dfrac{P_2V_2}{T_2}[/tex]

From the question, we have it that:

P1 is the initial pressure which is 475 torr

V1 is the initial volume which is 296 mL

T1 is the initial temperature which we have to convert to absolute value by adding 273.15 K ([tex]68 + 273.15 = 341.15 \ \text{K}[/tex])

P2 is the final pressure that is the same as the initial which is 475 torr

V2 is the final volume that we want to calculate

T2 is the final temperature which is 273.15 K (0 degrees Celsius is 273.15 K)

Substituting the values, we have:

            [tex]\dfrac{475\times296}{341.15}=\dfrac{475\times V_2}{273.15}[/tex]

[tex]V_2=\cfrac{475\times296\times273.15}{341.15\times475} =\boxed{\bold{237 \ mL}}[/tex]

A)By applying permutation and combination we can select committee in  1782 ways.

B) The probability cannot be determined with the given information, as the calculated probability is greater than 1, which is not possible.

Permutation and combination are two concepts in mathematics that deal with counting the number of possible outcomes or arrangements in a given situation. Permutation refers to the arrangement of objects in a specific order, while combination refers to the selection of objects without regard to the order in which they are chosen.

Probability is a measure of the likelihood or chance that an event will occur. It is a number between 0 and 1.

According to the given information:

A) To find the number of ways to select a committee of 5 members, where exactly one of Mr Lan and Mrs Lan must be on the committee, we can use the principle of inclusion-exclusion i.e. Permutation and combination:

First, we find the total number of ways to select a committee of 5 members from 14 members (6 men and 8 women), which is given by:

C(14,5) = 2002

Next, we find the number of ways to select a committee of 5 members that includes both Mr Lan and Mrs Lan, which is given by:

C(12,3) = 220

Note that we choose 3 members from the remaining 12 members after Mr and Mrs Lan have been chosen.

Finally, we subtract the number of committees that include both Mr Lan and Mrs Lan from the total number of committees, since we only want committees that include exactly one of them:

2002 - 220 = 1782

Therefore, there are 1782 different ways to select a committee of 5 members where exactly one of Mr Lan and Mrs Lan must be on the committee.

B) To find the probability that there are more women than men on the committee, given that Mrs Lan was selected, we need to consider the number of committees that satisfy this condition and divide by the total number of committees that include Mrs Lan.

If Mrs Lan is selected, there are two cases to consider:

Case 1: The committee has more women than men.

In this case, we need to select 4 members from the 8 women and 1 member from the 5 men, which can be done in C(8,4) x C(5,1) = 560 ways.

Case 2: The committee has an equal number or more men than women.

In this case, we need to select 3 members from the 8 women and 2 members from the 5 men, which can be done in C(8,3) x C(5,2) = 560 ways.

Therefore, the total number of committees that include Mrs Lan and have more women than men or an equal number of women and men is 560 + 560 = 1120.

The total number of committees that include Mrs Lan is C(13,4) = 715, since we choose 4 members from the remaining 13 members after Mrs Lan has been chosen.

Therefore, the probability of selecting a committee with more women than men or an equal number of women and men, given that Mrs Lan was selected, is:

1120/715 = 1.5664

Note that this probability is greater than 1, which is not possible. Therefore, there is an error in the calculation, and the correct probability cannot be determined with the given information.

The values of x and y that satisfy the system of equations are x = 8 and y = 4.

To solve for the values of x and y in the system of equations:

x + y = 12

2x + 5y = 36

We can use the method of substitution. Solving the first equation for x, we get:

x = 12 - y

We can substitute this expression for x into the second equation and solve for y:

2(12 - y) + 5y = 36

24 - 2y + 5y = 36

3y = 12

y = 4

Now that we know y is 4, we can substitute this value back into the first equation and solve for x:
