Option A is the correct answer as EF/QR = CE/SQ is not correct, as the triangles contain no vertex C.

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.

Although having the same form, each might have different sizes.

There are no matching angles that are not equal.

Similar equivalent side ratios exist.

Given that, EFG and QRS are similar.

We know that for similar triangles the ratio of length of the segments of the corresponding triangle are equal.

Thus, EF/QR = CE/SQ is not correct, as the triangles contain no vertex C.

The centroid of the region is at the point (0, 2/5).

To find the centroid of the region bounded by the curves y=2-x² and y=x, we first need to find the limits of integration and the expressions for the x-coordinate and y-coordinate of the centroid.

The curves intersect at (1,1) and (-1,1), so we will integrate over the interval [-1,1].

To find the x-coordinate of the centroid, we need to evaluate the following integral:

x' = (1/A) ∫[a,b] xf(x) dx

where;

A = ∫[a,b] (f(x) - g(x)) dx

In this case, f(x) = 2 - x² and g(x) = x, so

A = ∫[-1,1] (2 - x² - x) dx

= [2x - (1/3)x³ - (1/2)x²] | from -1 to 1

= (4/3)

Now we can evaluate the x-coordinate of the centroid:

x' = (1/A)∫[-1,1] x*(2-x²-x) dx

= (1/(4/3))∫[-1,1] (2x - x³ - x²) dx

= (3/4) [(x²/2) - (1/4)x⁴ - (1/3)x³] | from -1 to 1

= 0

So the x-coordinate of the centroid is 0.

To find the y-coordinate of the centroid, we need to evaluate the following integral:

y' = (1/A) ∫[a,b] (1/2) [f(x)² - g(x)²] dx

y' = (1/(4/3)) ∫[-1,1] (1/2)[(2-x²)² - x²] dx

= (3/4)[(8/15)x⁵ - (2/3)x³ + (1/2)x] | from -1 to 1

= (2/5)

So the y-coordinate of the centroid is 2/5.

Answer:

Step-by-step explanation:

To solve the differential equation x^2y'' − 3xy' + 3y = x^4e^x using variation of parameters, we can follow these steps:

Step 1: Find the complementary solution y_c by solving the homogeneous equation:

x^2y'' − 3xy' + 3y = 0

The characteristic equation is r(r-1) - 3r + 3 = 0, which simplifies to r^2 - 4r + 3 = 0. Factoring, we get (r-1)(r-3) = 0, so the roots are r=1 and r=3. Therefore, the complementary solution is:

y_c = c1x + c2x^3

where c1 and c2 are arbitrary constants.

Step 2: Find the particular solution y_p using variation of parameters. We assume that the particular solution has the form:

y_p = u1(x)*y1(x) + u2(x)*y2(x)

where y1 and y2 are solutions to the homogeneous equation (in this case, y1=x and y2=x^3) and u1 and u2 are functions to be determined.

We need to find the derivatives of y1 and y2:

y1' = 1, y1'' = 0

y2' = 3x^2, y2'' = 6x

Substituting into the differential equation and simplifying, we get:

x^2(u1''y1 + u2''y2) + x(u1'y1 + u2'y2) = x^4e^x

Plugging in y1 and y2 and simplifying, we get:

x^2(u1''*x + u2''*x^3) + x(u1'*1 + u2'*3x^2) = x^4e^x

We can write this equation in matrix form as:

[x^2x, x^2x^3] * [u1'', u2''] + [x1, x3x^2] * [u1', u2'] = [0, x^4e^x]

Taking the determinant of the coefficient matrix [x^2x, x^2x^3; x1, x3x^2], we get:

(x^2x)(x3x^2) - (x^2x^3)*x = 2x^4

Therefore, the inverse of the coefficient matrix is:

[3x, -x^3] / (2x^4)

Multiplying by the column vector [0, x^4e^x] gives:

[u1', u2'] = [3x, -x^3] * (1/(2x^4)) * [0, x^4e^x]

Simplifying, we get:

u1' = (3/2)*e^(-x), u2' = -(1/2)xe^(-x)

Integrating u1' and u2' with respect to x, we get:

u1 = -(3/2)*e^(-x), u2 = -(1/2)*xe^(-x) + C

where C is an arbitrary constant.

Therefore, the particular solution is:

y_p = -(3/2)xe^(-x) + Cx^3e^(-x)

where C is an arbitrary constant.

Step 3: The general solution of the differential equation is the sum of the complementary solution and the particular solution:

y = y_c + y_p

Step-by-step explanation:

√49 is a rational number. √50 is an irrational number. √127 is an irrational number. 125 is a rational number because it is equal to a perfect cube of the whole number 5.

A real number is considered to be irrational if it cannot be written as a simple fraction. It cannot be described using a ratio. When p and q are numbers and q is not identical to 0, N is not equivalent to p/q if N is irrational. An illustration of this is the illogic of the integers

A actual number that's unable to be written as the ratio between two integers—that is, as p/q, where both p and q both are integers—is an irrational number.

√49 is a rational number because it is equal to 7, which is a whole number.

√50 is an irrational number because it cannot be expressed as a fraction of two integers and it is not a perfect square.

√127 is also an irrational number because it cannot be expressed as a fraction of two integers and it is not a perfect square.

125 is a rational number because it can be expressed as 5^3, which is a perfect cube of the whole number 5.

Therefore, the correct statements are:

The image triangle has vertices after the dilation by a scale factor of 3 are M'(0,12), N'(12,6), and P'(6,-6).

To find the image coordinates of a triangle after dilation, we need to multiply the coordinates of each point by the scale factor.

In this case, the scale factor is 3.

So the image coordinates of the triangle with vertices M(0,4), N(4,2), and P(2,-2) after dilation by a scale factor of 3 are:

M' = (3 * 0, 3 * 4) = (0, 12)

N' = (3 * 4, 3 * 2) = (12, 6)

P' = (3 * 2, 3 * (-2)) = (6, -6)

Hence, the image triangle has vertices M'(0,12), N'(12,6), and P'(6,-6).

In summary, the image coordinates of the triangle after dilation by a scale factor of 3 are M'(0,12), N'(12,6), and P'(6,-6).

2) Predicted year when the population will reach 54000 = 2020

3) The rate of population changes = 2150

4) The number of years for the population doubled since 2008 =9.12

What is a linear equation?

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant.

Given,

the population in 2008 = 28,200

the population in 2012 = 36,800

The population is growing linearly.

Assume a linear equation,

p(x) = 36800 + kx

where,

   p(x) = population

  x = years since 2012.

k = increase in population

p(0) = 36800

p(-4) = 36800 - 4k

28200= 36800 -4k

4k = 36800 - 28200

k = 2150

Then the linear equation becomes,

p(x) = 36800 + 2150x

1) Population in 2014

x = 2014 - 2012 = 2

From the equation,

p(2) = 36800 + 2150 * 2 = 41100

2) x when p(x) = 54000

From the equation,

54000  = 36800 + 2150x

2150x = 17200

x = 8

Year = 2012 + 8 = 2020

3) Rate of population change = (population in 2012 - population in 2008) / number of years = 36800-28200 / 4 = 2150

4) Population doubled since 2008

p(x) = 2 * 28200 = 56400

We have to find x , when p(x) = 56400

Using the linear equation,

56400 = 36800 + 2150x

x = 9.12

Therefore using the equation, we found the following:

1) Expected Population in the year 2014 = 41100

2) Predicted year when the population will reach 54000 = 2020

3) The rate of population changes = 2150

First, we need to find the number of people who went to the pool in the second, third, and fourth weeks.

Number of people in second week = 1,120 - 125 = 995

Number of people in third week = 995 + 145 = 1,140

Number of people in fourth week = 1,140 - 132 = 1,008

To find the percent decrease, we need to find the difference between the number of people in the first week and the fourth week, and then divide by the number of people in the first week.

Difference between first and fourth weeks = 1,120 - 1,008 = 112

Percent decrease = (112/1,120) x 100% = 10%

Therefore, the percent decrease in the number of people who went to the pool over these four weeks is 10%.
