The answer  is ,  the total number of positive integers less than 1000 with a digit sum of 4 is 35 - 20 = 15.

An integer is a whole number that can be positive, negative, or zero, but does not have any fractional or decimal parts. Integers can be represented on the number line, with zero at the center and positive integers to the right and negative integers to the left.

We  use technique called "stars and bars" to solve this problem.

Using this approach, the number of positive integers less than 1000 with a digit sum of 4 is equal to the number of ways to arrange 4 stars and 3 bars. We can choose the positions of the bars in 7 ways (i.e., there are 7 places where we can place a bar), so the total number of such arrangements is 7 choose 3 (i.e., we choose 3 places for the bars out of the 7 possible places), which is:

7 choose 3 = 7! / (3! * (7-3)!) = 35

Note that we need to subtract the number of solutions that have 0 as the first digit, since we are only looking for positive integers. We can choose the positions of the bars in 6 ways (i.e., we cannot place a bar before the first star), so the number of such arrangements is 6 choose 3, which is:

6 choose 3 = 6! / (3! * (6-3)!) = 20

Therefore, the total number of positive integers less than 1000 with a digit sum of 4 is 35 - 20 = 15.

Step-by-step explanation:

The area of the shaded region is 83.3% of the area of the sector ONQ.

First, let's find the area of the sector ONQ:

The formula for area of a sector is;

Area of sector = (angle/360) x πr²

In this case, the angle of the sector ONQ is 120 degrees (since AOB is an equilateral triangle and each angle of an equilateral triangle is 60 degrees). So;

Area of sector ONQ = (120/360) x π(11²)

= 127.2 cm²

Next, we need to find the area of the equilateral triangle AOB:

The formula for area of an equilateral triangle is;

Area of equilateral triangle = (√3/4) x s²

where s is length of a side of the triangle.

In this case, s =7 cm, so;

Area of equilateral triangle AOB = (√3/4) x (7²) = 21.2 cm²

Now we can find the area of the shaded region (which is the area of sector ONQ minus the area of triangle AOB);

Area of shaded region = Area of sector ONQ - Area of equilateral triangle AOB

= 127.2 - 21.2

= 106 cm²

Finally, we can express the area of the shaded region as a percentage of the area of sector ONQ;

Percentage = (Area of shaded region / Area of sector ONQ) x 100%

= (106 / 127.2) x 100%

= 83.3%

Therefore, the area of the shaded region is 83.3%

What is revenue?

Revenue means money received in the ordinary course of business and is calculated by multiplying the average selling price by the number of items sold. This is the total amount of money from which other costs and expenses are subtracted to calculate net income.

The definition of revenue says it is the total amount of money received from a business, such as sales. This is also called sales in the income statement. This is a top-line figure because it appears first on the company's income statement. There are two types of income i.e. operating income and non-operating income.

Here, the most likely way to generate revenue to pay for a new national water pollution abatement plan is for the United States Senate to pass a bill that raises the federal income tax rate that would then pay for the service. This is because it directly increases the funds available to the federal government, which can then be allocated to a new public service. Other options, such as homeowners paying higher property taxes or states raising sales taxes, may not generate enough revenue or may not be directly related to the new public service. Furthermore, selling clean water to other countries may not be sustainable or ethical to fund a public service.

We can use the Law of Sines to solve for the sides of the triangle. The Law of Sines states that for any triangle with sides a, b, and c opposite angles A, B, and C, respectively:

a/sin A = b/sin B = c/sin C

We can use this formula to solve for any side of a triangle if we know the measures of two angles and the length of one side.

Let's label the sides of the triangle as follows:

a is opposite angle A (which measures 47°)

b is opposite angle B (which measures 36°)

c is opposite angle C (which measures 97°)

We want to find the largest side, so let's solve for all three sides using the Law of Sines and then compare them:

a/sin 47° = b/sin 36° = c/sin 97°

Solving for a:

a = sin 47° (b/sin 36°) = (sin 47°/sin 36°) b

Solving for b:

b = sin 36° (a/sin 47°) = (sin 36°/sin 47°) a

Solving for c:

c = sin 97° (a/sin 47°) = (sin 97°/sin 47°) a

To compare the sides, we can simply compare the coefficients in front of a and b:

a = (sin 47°/sin 36°) b ≈ 1.336 b

c = (sin 97°/sin 47°) a ≈ 2.117 a

Therefore, c is the largest side of the triangle. We can find its exact value by plugging in the given angle measures:

c = (sin 97°/sin 47°) a ≈ 2.117 a

a/sin 47° = c/sin 97°

a = (sin 47°/sin 97°) c ≈ 0.702 c

So the largest side, c, is approximately 2.117 times the length of the smallest side, a. We don't know the actual length of any side, since we don't have any side lengths to use as reference.

Answer:

In any triangle, the sum of the angles is always 180 degrees. So we can use this fact to find the measure of angle A and angle B:

m∠C + m∠A + m∠B = 180

Substituting the given values, we get:

97° + 47° + 36° = 180°

Simplifying this equation, we get:

180° = 180°

This confirms that the given angle measures are valid.

To find the largest side of the triangle, we can use the law of sines, which relates the sides of a triangle to the sines of their opposite angles:

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the lengths of the sides opposite angles A, B, and C, respectively.

We want to find the largest side, which is opposite the largest angle. Since angle C is the largest angle, we can set up the proportion:

a/sin(A) = b/sin(B) = c/sin(C)

a/sin(47°) = b/sin(36°) = c/sin(97°)

To find the largest side, we need to find the largest value of the expression a/sin(47°). We can start by finding the value of b/sin(36°) and c/sin(97°) using the given information.

Using the law of sines, we can write:

b/sin(36°) = c/sin(97°)

b = (sin(36°)/sin(97°))c

Now, substituting this expression for b, we get:

a/sin(47°) = (sin(36°)/sin(97°))c/sin(36°)

Simplifying this expression, we get:

a/sin(47°) = c/sin(97°)

a = (sin(47°)/sin(97°))c

Now, we need to find the value of c. Using the law of sines again, we can write:

a/sin(47°) = b/sin(36°) = c/sin(97°)

c = (sin(97°)/sin(47°))a

Substituting the expression we found for a, we get:

c = (sin(97°)/sin(47°))(sin(47°)/sin(97°))c

c = c

So, we see that c is equal to itself, which doesn't give us any new information. However, we can use the expression we found for a to determine the largest side:

a = (sin(47°)/sin(97°))c

Since sin(47°) < sin(90°) and sin(97°) > sin(90°), we know that sin(47°)/sin(97°) < 1. Therefore, the largest side of the triangle is c, which is opposite the largest angle, angle C.

In conclusion, we cannot determine the exact length of the largest side without additional information, but we know that it is opposite angle C, which has a measure of 97 degrees.

The combination of existing functions is not limited to function composition. Another method is to do addition, subtraction, multiplication, and division on the functions using standard algebraic operations.

In mathematics, the process of "function composition" combines two functions, f and g, to produce h = g f, where h(x) = g(f(x)).

Function composition is the process of combining two functions to produce a third function.

Simply using the first function's output as the input for the second function is how it works.

The function g is applied in this operation on the outcome of applying the function f to x.

In other words, the functions f: X Y and g: Y Z are combined to create a function that maps x in domain X to g(f(x)) in codomain Z. If z were a function of y and y were a function of x, it seems sensible that z would be a function of x.

The final composite function is denoted by the notation (g f)(x) = g(f(x)) for all x in X, and is represented by the notation g f: X Z. [nb 1]

Answer:

B(x) appears to be an exponential function because the population increases at a constant rate over time. This can be seen by observing that the population roughly triples with each passing year, indicating that the function is of the form B(x) = ab^x, where a is the initial population and b is the growth factor. To confirm this, we can calculate the growth factor by dividing the population at each successive year by the population in the previous year. For example, we have:

b = B(1)/B(0) = 6/2 = 3

b = B(2)/B(1) = 18/6 = 3

b = B(3)/B(2) = 54/18 = 3

and so on.

M(x) appears to be a quadratic function because the population growth rate is not constant, but rather increases over time. This can be seen by observing that the rate of increase in the population growth appears to accelerate as time goes on, suggesting that the function is of the form M(x) = ax^2 + bx + c, where a, b, and c are constants. To confirm this, we can plot the data and observe that the graph has a parabolic shape.

S(x) also appears to be a quadratic function for similar reasons to M(x), where the population growth rate increases over time.

From the given data, the function S(x) appears to be the same type as W(x) because both are quadratic functions. Both functions appear to have an increasing rate of growth over time.

Step-by-step explanation:

The data presented shows the growth of the Javanese gibbon population on three different islands over time.

Data trends must be analyzed to determine the type of function that is modeling population growth. A common way to do this is to plot the data points and observe the shape of the curve. However, since the table only contains data, you can analyze trends by looking at the differences between consecutive terms.

To do this, we can calculate the first difference and the second difference in the population data.

The first difference:

- Swing: 40 - 30 = 10, 50 - 40 = 10, 60 - 50 = 10

Example: 60 - 50 = 10, 75 - 60 = 15, 90 - 75 = 15

- Salavati: 80 - 60 = 20, 100 - 80 = 20, 120 - 100 = 20

The second difference:

- Batanta: 10 - 10 = 0, 10 - 10 = 0

- Example: 15 - 10 = 5, 15 - 15 = 0

- Salavati: 20 - 20 = 0, 20 - 20 = 0

The first difference is constant for each island and shows a linear relationship between time and population growth. Also, the second difference is zero, indicating a constant rate of change.

Therefore, we can conclude that the population growth modeling function is a linear function that can be written as

M(x) = mx + b

where x is the time in years, m is the slope (population growth rate), and b is the y-intercept (initial population).

If Thabang worked for three hours and Ndivhu worked for two hours, then the total number of hours worked is five. To determine the amount Thabang will receive if they decided to share their money according to hours, we need to calculate the proportion of the total hours that Thabang worked and multiply that by the total amount of money earned.

Thabang worked for three out of five hours, which is 3/5 or 0.6 of the total time. To find out how much money he should receive, we can multiply this fraction by the total amount earned:

0.6 x R400 = R240

Out of 220 students, 44 would like dogs more than cats.

How to find the number of students who like dogs more than cats?

First, we know that 20 students like dogs and 12 like cats, so there are 20 - 12 = 8 more students who like dogs than cats.

We also know that there are 40 students in total, so the percentage of students who like dogs more than cats is 8/40 = 0.2.

To find the number of students who would like dogs more than cats among 220 students, we can use the same percentage:

We know that there are 220 students in total, so the number of students who would like dogs more than cats is 0.2 × 220 = 44.

The angle measure of RUT is m∠RUT = 33°.

The diameter of an arc within a circle is equal to the diameter of the central angle that subtends the arc.

Therefore, if we know the length of an arc, we may calculate the length of its corresponding central angle.

In this case, we are given that the measure of the minor arc RT is 66°.

We need to find the measure of angle RUT.

We achieve this by taking use of the fact that an inscribed angle's measure is half that of its equivalent central angle.

Since angle RUT is an inscribed angle that intercepts arc RT, we have:

m∠RUT = 1/2 × m/RT

m∠RUT = 1/2 × 66°

m∠RUT = 33°.

Therefore, the measure of angle RUT is 33°.
