Answer:

The equation x²+12x+43=0 is a quadratic equation that can be solved by factoring or using the quadratic formula.

Factoring the equation:

x²+12x+43=(x+7)(x+6)=0

x+7=0 or x+6=0

x=-7 and x=-6

Therefore, the solutions for the equation are x=-7 and x=-6.

Alternatively, you can use the quadratic formula:

x = (-b± √(b²-4ac))/2a

Where a=1, b=12, c=43

x = (-12± √(12²-4143))/2*1

x = (-12± √(144-172))/2

x = (-12± √(-28))/2

x = (-12± i*√28)/2

x = (-12+ i2√7)/2 or x = (-12- i2√7)/2

These solutions are complex numbers, x = (-6+2i√7) or x = (-6-2i√7)

The total amount owed to the lender equals $2,330.

In our calculate, we are using a simple interest because it is only an interest charge that borrowers pay lenders for a loan. It is calculated by using the principal only and does not include compounding interest.

Data

Loan = $2000.00

Interest rate = 5.5%

Time = 3 years

The total amount owed:

= Loan + Interest.

To get our Interest, we will use "S.I. = PRT/100"

= 2000.00 * 5.5% * 3

= $330

Hence, the total amount owed equals to

= $2,000 + $330

= $2,330.

An exponential function is a function in which the variable is in the exponent. The general form of an exponential function is f(x) = ab^x, where a and b are constants.

The variable x is the exponent, meaning that it is raised to a certain power, resulting in the variable being in the exponent. In this function, the value of the function increases or decreases at a rate that is proportionate to the current value of the function.

This type of function is commonly used in modeling growth or decay in various fields such as biology, economics, and physics. The exponential function generates a sequence that is exponential in nature, the rate of change of the function is directly proportional to the value of the function.

Step-by-step explanation:

The slope of y = -9 is 0.

In mathematics, the slope of a line is a number that describes both the direction and the steepness of the line. It is commonly denoted by the letter "m".

The slope is defined as the ratio of the "rise" (change in the y-coordinate) to the "run" (change in the x-coordinate) between any two distinct points on the line. It is also known as the gradient of the line.

A line with a positive slope goes up as it goes to the right, while a line with a negative slope goes down as it goes to the right. A line with a slope of zero is horizontal, and a line with undefined slope is vertical.

The equation y = -9  is a horizontal line, hence, the slope is 0.

The 3 types straight line are

1. Slope-intercept form: y = mx + b

2. Point-slope form: y - y1 = m(x - x1)

3. Standard form: ax + by = c

1. Slope-intercept form: y = mx + b - This is the most common form of a straight line; it is composed of two parts: m (the slope of the line) and b (the y-intercept). To use this form, you need to know the slope (m) of the line and the y-intercept (b). From this information, you can calculate the equation of the line by substituting the values of m and b into the equation.

2. Point-slope form: y - y1 = m(x - x1) - This form of a straight line requires two points on the line and the slope of the line. To use this form, you need to know the two points on the line (x1, y1) and the slope of the line (m). Then, you can calculate the equation of the line by substituting the values of x1, y1 and m into the equation.

3. Standard form: ax + by = c - This form of a straight line is composed of three parts: a (the coefficient of x), b (the coefficient of y) and c (the constant). To use this form, you need to know the coefficients of x and y and the constant. From this information, you can calculate the equation of the line by substituting the values of a, b and c into the equation.

The values are calculated using the basic properties as follows.

Trigonometric functions are defined as the real functions which are simply the functions of an angle of a triangle. They are basically the periodic functions which relate an angle in a right angled triangle to the ratios of the length of two sides.

Trigonometric functions are also called as Circular functions.

Given sin θ = [tex]\frac{3}{7}[/tex] and cot θ = [tex]\frac{2\sqrt{10} }{3}[/tex]

In order to solve this, you need to know some of the basic trigonometric properties.

1. cot θ = 1 / tan θ

tan θ = sin θ / cos θ

So, cot θ = cos θ / sin θ

[tex]\frac{2\sqrt{10} }{3}[/tex] = cos θ /  [tex]\frac{3}{7}[/tex]

cos θ =  [tex]\frac{2\sqrt{10} }{3}[/tex] ×  [tex]\frac{3}{7}[/tex]

cos θ = [tex]\frac{2\sqrt{10} }{7}[/tex]

2. tan θ = 1 / cot θ

tan θ = 1 / [[tex]\frac{2\sqrt{10} }{3}[/tex]]

tan θ = [tex]\frac{3}{2\sqrt{10} }[/tex]

3. sec θ = 1 / cos θ

sec θ = 1 / [[tex]\frac{2\sqrt{10} }{7}[/tex]]

sec θ = [tex]\frac{7}{2\sqrt{10} }[/tex]

4. csc θ = 1 / sin θ

csc θ = 1 / [[tex]\frac{3}{7}[/tex]]

csc θ = [tex]\frac{7}{3}[/tex]

Hence the values of the trigonometric functions are calculated.

The domain of the composite function is the intersection of the domain of f(x) and G(x). D f(x) intersection D g(x) The range of the function is now restricted by the domain of the composite function.

Therefore, the range is found by evaluating the function at the points in the domain of f(x).

You find the domain of the function by finding all numbers that can't go into the equation. Usually all that prevents this is whether or not it contains a fraction with x on the bottom or a x under a square root .

The range is found by finding the vertex and noting that it is the minimum or maximum (depending on direction) of the graph. You can find the vertex by using -b/2a for the x value and then plugging in to get y value.

The given function f(x) = –37 is a horizontal line which goes from negative infinity to positive infinity.

In this case, the domain can be any number since there is no limit on what the x value can be.

So, the domain of the given function f(x) = –37 will be all real numbers.

And, the range will always be y = –37 because no matter what x value will equal, y will always be equal to –37 in the function of f(x) = –37.

The line of best fit to represent the given data would be y = 13.5x + 10.

What is the best-fit line in statistics?

A best-fit line, also known as a line of best fit, is a straight line that is used to model the relationship between two variables in a set of data.

A line of best fit is a straight line that is the best approximation of the data points. To find a line of best fit, you can use the method of least squares, which involves minimizing the sum of the squared differences between the data points and the line.

Given the data (x,y) = {(0,10), (1,12), (2,15), (3,20), (4,30)}, the slope of the line can be calculated using the formula:

slope = (NΣ(xy) - Σx * Σy) / (NΣ(x^2) - (Σx)^2)

Where N is the number of data points.

Plugging in the data:

slope = (5*(10+24+30+60+120) - (0+1+2+3+4)(10+12+15+20+30)) / (5(0+1+4+9+16) - (0+1+2+3+4)^2)

slope = 270/20 = 13.5

y-intercept can be calculated using the formula:

y-intercept = (Σy - slopeΣx)/N

y-intercept = (10+12+15+20+30 - 13.5(0+1+2+3+4))/5

y-intercept = 10

So, the equation of the line of best fit would be:

y = 13.5x + 10

This equation represents a line with a slope of 13.5 and a y-intercept of 10. This line of best fit can be used to make predictions about the ticket price for a given number of years since 1980.

Hence, the line of best fit to represent the given data would be y = 13.5x + 10.

In the given set of data, 4/5 is the constant of proportionality in the proportional relationship.

When two or more parameters are either directly or indirectly proportional to one another, the relationship is written as a = kb or a = k/b, where k denotes the direction of the relationship between the two variables. The proportionality constant, k, is defined as follows.

The ratio of two proportional values at a constant value serves as the definition of the proportionality constant. When the product or ratio of two variables yields a constant, the relationship between the two is proportional. By comparing the ratio of the two specified quantities, we can calculate the value of the proportionality constant. A direct variation or an inverse variation of this relationship are both possible.

Given
