The population of the city in 2023 is 1.6 * 10^6.

The exponential function is a mathematical function that describes the growth of a quantity as a power of another quantity.

In mathematics, the exponential function is used to model a wide range of phenomena including exponential decay, compounding interest, and population growth.

Using the exponential growth model;

P = Poe^rt

P = population at time t

Po = Initial population

r = Population growth rate

t = time

4Po = Poe^rt

If t = 1

4Po/Po = e^r

with four-page frames, we can see that there will be multiple page faults. Initially, all four frames are empty, so there will be four page faults as the first four pages are brought into memory.

Then, when page 5 is needed, the oldest page in memory, page 1, is replaced leading to another page fault.

As the reference string continues, there are several page faults that occur as pages are replaced

The measure of each angle are 94.2° and 85.8°.

Let's call the measure of the first angle x.

Since the angle is supplementary to another angle, their measures add up to 180°.

So, the measure of the second angle is 180° - x.

Also, the first angle measures 8.4° more than the second angle, so:

x = (180° - x) + 8.4°

Solving for x:

2x = 188.4°

x = 94.2°

So the first angle measures 94.2° and the second angle measures 180° - 94.2° = 85.8°.

The function sin(x-y)/cosec(x+y)=sin²x-sin²y

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

We have to prove that sin(x-y)/cosec(x+y)=sin²x-sin²y

Using the identity cosecx=1/sinx

We get sin(x-y)/cosec(x+y)=sin(x-y)sin(x+y)

We know sin(x+y)=sinxcosy+cosxsiny

sin(x-y)=sinxcosy-cosxsiny

Now sin(x-y)sin(x+y)=(sinxcosy-cosxsiny)(sinxcosy+cosxsiny)

=sin²xcos²y-cos²xsin²y

=sin²x(1-sin²y)-(1-sin²x)sin²y

=sin²x-sin²xsin²y-sin²y+sin²xsin²y

=sin²x-sin²y

Hence, we proved that sin(x-y)/cosec(x+y)=sin²x-sin²y

The equation does not hold true, indicating that point C does not lie on line AB.

The equation of line AB can be written in slope intercept form as y = mx + b. The slope of line AB can be found using the equation m = (y2-y1)/(x2-x1). Substituting the coordinates of points A and B into the equation, we get m = (2-4)/(-5-2) = -2/7. The slope-intercept form of this equation is y = -2/7x + b. We can find the value of b by substituting the coordinates of point A into the equation. We get b = 4 + 2/7 = 19/7.

Therefore, the equation of AB in slope-intercept form is y = -2/7x + 19/7. To check whether point C lies on line AB, we must substitute the coordinates of point C into the equation. We get y = -2/7(-1)+19/7 = -2/7 + 19/7 = 17/7. Since the y-coordinate of point C is 8, the equation does not hold true, indicating that point C does not lie on line AB.

Answer: An argument is a value passed to a function. A parameter variable is a variable local to the function which receives the argument.

Step-by-step explanation:

The term "argument" refers to the values that are specified inside a function when the function is invoked. The variables that are defined when the function is declared, however, are referred to as parameters.

What is Function?

A relation between a collection of inputs and outputs is known as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function.

The term "argument" refers to the values that are specified inside a function when the function is invoked. The variables that are defined when the function is declared, however, are referred to as parameters.

argument:

These are employed in function call statements in order to transfer value from the calling function to the receiving function.

Also called as Actual Parameters, they are.

Each argument is always assigned to the parameter specified in the function specification during the call.

Parameter:

These are utilised in the called function's function header to obtain the value from the parameters.

The function is P = 35(1.3)^t

At t = 0, P = 35, so P(0) = 35

P = 35e^{kt} .................Equation 1

P = 35(1.3)^t .................Equation 2

Now dividing the equation, we get

The correct solution are,

(C) a=1, b=2, c=3.

The code segment does not work in the case where a > b, c > b, but a < c.

In this case, the value of 'low' is set to 'b' instead of 'a', which causes the code segment to print the incorrect value.

The values of a, b, and c that fall into this case are a=1, b=2, and c=3.

Let's trace through the code segment using a=1, b=2, and c=3:

Since a=1 and b=2, the first conditional statement (a > b && b > c) evaluates to false, so we skip the first 'if' block.

Since a=1 and c=3, the second conditional statement (a > b && c > b) evaluates to true, so we set 'low' to 'b'.

However, since we have an 'else' block following the second conditional statement, it will always be executed. So, 'low' is set to 'a' instead.

Finally, the code segment prints the sum of a + b + c - low, which is 1+2+3-1 = 5, which is incorrect.

The correct answer should be 1 + 3 = 4.

Therefore, the answer is (C) a=1, b=2, c=3.

Answer:

The transformation to make the graph of y=1/x^2 into y=1/(x-2)^2 +3 involves shifting the graph horizontally by 2 units to the right, and vertically by 3 units up.

The transformation can be achieved by applying the following changes to the original equation:

Substitute x with (x-2) in the denominator of the fraction: 1/(x-2)^2

Add 3 to the fraction: 1/(x-2)^2 +3

This will give us the new equation y=1/(x-2)^2 +3, and the graph of this equation will be a parabola shifted 2 units to the right and 3 units up from the original graph of y=1/x^2.

The inverse function of the function g(x) will be y = √(x) - 10.

Let the function f is given as

y = m(x + a) + c

Then the inverse function of the function f will be given by swapping x with y and y with x.

An equation is an expression showing the relationship between two or more numbers and variables. An equation can either be linear, quadratic, cubic and so on depending on the degree.

Speed is the ratio of total distance travelled to total time taken. It is given by the equation:

Speed = distance / time

1 hour = 60 minutes

She ran 6 miles in 50 minutes.

50 minutes = 50 min * 1 hr per 60 min = 5/6 hr

Speed on Wednesday = distance / time = 6 miles / (5/6)hr = 7.2 mph

She ran 4 miles in 32 minutes.

32 minutes = 32 min * 1 hr per 60 min = 8/15 hr

The polynomial 5s2 + 5s - 30 can be factored as (s + 6)(s - 5). This is done by finding two numbers whose product is -30 and whose sum is 5. They are -6 and 5.

The factored representation of the polynomial 5s2 + 5s - 30 can be found by factoring. First, we need to find two numbers whose product is -30 and whose sum is 5. This can be done by trial and error or by using the Fundamental Theorem of Algebra. When these two numbers are found, the polynomial can be factored as (s + 6)(s - 5). To factor the polynomial, we can use the factor theorem. This states that if a and b are factors of a polynomial, then (x-a) and (x-b) are factors of the polynomial. In our case, a=6 and b=-5. So, the polynomial can be written as (s + 6)(s - 5). We can then use the distributive property to expand the polynomial and verify that it is the same as the original polynomial.

The total surface area painted black is 12.6 sq. feet.

The surface area of a cone with height h and circumference of the base c can be calculated using the formula:

A = πr^2 + πrs,

where,

r = the radius of the base

s = the slant height.

We can find the radius of the base by dividing the circumference by 2π:

r = c / (2π)

  = 8π / (2π)

r = 4.

The slant height can be found using the Pythagorean theorem:

s = √(r² + h²)

  = √(4² + 12²)

  = √(16 + 144)

  = √(160)

s = 12.7279

So the surface area of each cone is:

A = πr² + πrs

= π * 4² + π * 4 * 12.7279

= 3.14 * 4² + 3.14 * 12.7279

= 50.265...

The base and 50% of the lateral surface are painted red, which is a total of 50% + 100% / 2 = 75% of the surface area.

So the total surface area painted black is:

By completing squares, we will see that the solutions of the given quadratic equation are:

x = -3 ± √(21/2)

Here we know that Inga is solving the quadratic equation below:

2x² + 12x - 3 = 0

The steps that she can do is try to complete squares, first we can take the 2 as a common factor to get:

2(x² + 6x) - 3 = 0

Now we can add 18 in both sides, then we will get:

2(x² + 6x) - 3 + 18 = 18

We can put that 18 inside the first term:

2(x² + 6x + 9) - 3  = 18

And now we can complete squares, because:

x² + 6x + 9 = x² + 2*3*x + 3² = (x + 3)²

Replacing that we will get:

2(x + 3)² - 3 = 18

2(x + 3)²= 18 + 3 = 21

2(x + 3)² = 21

(x + 3)² = 21/2
