The equation of the normal line to the curve is y = -x + π

To find the equation of the normal line to the curve y = sin(sinx) at x = π, we need to find the slope of the tangent line at x = π and then use that to determine the slope of the normal line. We can find the slope of the tangent line by taking the derivative of y with respect to x and evaluating it at x = π.

y = sin(sinx)

Taking the derivative with respect to x, we get:

dy/dx = cos(sinx) * cosx

At x = π, we have:

dy/dx = cos(sin(π)) * cos(π) = -1 * (-1) = 1

So the slope of the tangent line at x = π is 1. Since the normal line is perpendicular to the tangent line, its slope is the negative reciprocal of 1, which is -1.

Now we need to find the y-intercept of the normal line, which is the point where the line intersects the y-axis. To do this, we can plug in the values of x = π and y = sin(sinx) = sin(sin(π)) = 0 into the equation of the line:

y = mx + b

0 = -1 * π + b

b = π

So the equation of the normal line is:

y = -x + π

Assuming that 9x2 is [tex]9x^{2}[/tex], the length would be x + 5.

Step-by-step explanation:

The area of a rectangle is length times width.

It's given that the width is 9x, so the length must be multiplied by 9x to get 9x^2 + 45x.

9x * x = 9x^2 and 9x * 5 = 45x

So, 9x(x + 5) = 9x^2 + 45x

The area of the rectangle can be denoted using the expression, (x + 5).

The area of a rectangle is represented by the product of its length and width.

ar RECTANGLE = length X width

to find out the Length of the rectangle, we need to put the following values in the formula:

area = 9x^2 + 45x

width = 9x

let us assume length = L

putting the above values in the formula we get:

9x^2 + 45x = 9x * L

simplifying the area by taking out the common factor, we can write the area to be:

9x * ( x+ 5)

now,

L = [9x * (x+ 5)] / 9x

L = ( x + 5)

Therefore the length of the rectangle can be represented by using the expression; x + 5.

Based on the arithmetic sequence with the first term −5 and the common difference 4 is 660, we could find m = 20.

To find the sum of the first m terms of an arithmetic sequence, we can use the formula:

sum = (m/2)(2a + (m-1)d),

where a is the first term,

d is the common difference,

and m is the number of terms.

In this case, we are given a = −5, d = 4, and sum = 660. We can plug these values into the formula and solve for m:
660 = (m/2)(2(-5) + (m-1)(4))
660 = (m/2)(-10 + 4m - 4)
660 = (m/2)(4m - 14)
1320 = m(4m - 14)
0 = 4m^2 - 14m - 1320

Now we can use the quadratic formula to solve for m:
m = (-b ± √(b^2 - 4ac))/(2a)
m = (-(−14) ± √((−14)^2 - 4(4)(-1320)))/(2(4))
m = (14 ± √(196 + 21120))/8
m = (14 ± √21316)/8
m = (14 ± 146)/8

Now we have two possible values for m:
m = (14 + 146)/8 = 160/8 = 20
m = (14 - 146)/8 = -132/8 = -16.5

Since m must be a positive integer, we can conclude that m = 20. Therefore, the sum of the first 20 terms of the arithmetic sequence is 660.

The center of the dilation, point C, is located at the same point as it was before the dilation. This is because the center of dilation is the point from which the dilation occurs, and it does not change during the dilation process.

To find the coordinates of point C, we can use the properties of dilations. The coordinates of the vertices of the dilated triangle are found by multiplying the coordinates of the original triangle by the scale factor.

So, if the coordinates of point X are (x1, y1), the coordinates of point X' will be (0.5x1, 0.5y1). Similarly, the coordinates of point Y' will be (0.5x2, 0.5y2) and the coordinates of point Z' will be (0.5x3, 0.5y3), where (x2, y2) and (x3, y3) are the coordinates of points Y and Z, respectively.

Since point C is the center of dilation, the coordinates of point C will be the same as the coordinates of the midpoint of the line segment connecting points X and X', points Y and Y', and points Z and Z'. The midpoint of a line segment is found by averaging the coordinates of the endpoints. So, the coordinates of point C will be:

C = ((x1 + 0.5x1)/2, (y1 + 0.5y1)/2) = (0.75x1, 0.75y1)

Therefore, the center of the dilation, point C, is located at (0.75x1, 0.75y1).

A regression line is a line of​ means, and outliers have a big effect on the regression line.

Regression:

Regression is a statistical method used in finance, investing, and other disciplines that attempts to determine the strength and character of the relationship between a dependent variable (usually denoted by Y) and a set of other variables (called variables independent). Also known as simple regression or ordinary least squares (OLS), linear regression is the most common form of this technique. Linear regression establishes a linear relationship between two variables based on a line of best fit. So the linear regression is plotted with a straight line and the slope defines how changes in one variable affect changes in the other variable.

Regression Line:

Regression lines are very useful for the forecasting process. The purpose of this line is to describe the relationship between the dependent variable (variable Y) and one or more independent variables (variable X). Using the equation obtained from the regression line, the analyst can predict the future behavior of the dependent variable by entering different values ​​for the independent variable. Regression lines are widely used in the financial industry and in business in general.

The regression line formula is like the following:

Y = a + bX + u

The multiple regression formula looks like this:

Y = a + b₁X₁ + b₂X₂ + b₃X₃ + … + btXt +u.

Y is the dependent variable

X is the independent ones

a is the interception point

b is the slope

A system of three linear equations: for the total number of tickets sold is 215 is f + s + t = 215, for the total revenue from ticket sales is $1214 is 7f + 5.25s + 5.5t = 1214, for three times as many senior citizen tickets were sold as full-price tickets is s = 3f.  

There were approximately 11 full-price tickets sold. There were 33 senior citizen tickets sold. There were 171 student tickets sold.

Let f, s, t be the number of full-price tickets sold, senior citizen tickets sold, student tickets sold.

Firstly, write a system of three linear equations based on the given information and mark the equation number.

f + s + t = 215      (1)        (the total number of tickets sold is 215)

7f + 5.25s + 5.5t = 1214   (2)  (the total revenue from ticket sales is $1214)

s = 3f          (3)           (three times as many senior citizen tickets were sold as full-price tickets)

solve this system by substitution. Using equation (3), we can substitute 3f for s in equations (1) and (2):

f + 3f + t = 215

7f + 5.25(3f) + 5.5t = 1214

Simplifying these equations gives:

4f + t = 215           (4)

24.75f + 5.5t = 1214   (5)

We can solve equation (4) for t to get:

t = 215 - 4f

We can substitute this expression for t in equation (5) and solve for f:

24.75f + 5.5(215 - 4f) = 1214

24.75f + 1182.5 - 22f = 1214

2.75f = 31.5

f = 11.45 ≈ 11

Therefore, approximately 11 full-price tickets were sold. Using equation (3), we can find the number of senior citizen tickets sold:

s = 3f = 3(11) = 33

Therefore, 33 senior citizen tickets were sold. Finally, we can use equation (1) to find the number of student tickets sold:

f + s + t = 215

11 + 33 + t = 215

t = 171

Therefore, 171 student tickets were sold.
