The values are calculated using the basic properties as follows.
What are Trigonometric Functions?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.

x²+12x+43=0 Perfect Square Trinomals
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)
Charles checks his pocket for change. He notices that he has 20 coins in dimes and quarters for a total of

Part A
Formulate a system of equations to represent this situation.
Part B
Solve the system of equations to determine the number of dimes and the number of quarters Charles has
in his pocket.
Therefore , the solution of the given problem of equation comes out to be 12 pennies.
Analyze the equation.A equation is a method that links two statements and signifies equivalence with the equals sign (=). In algebra, a scientific assertion that confirms the equivalency of two schemas is referred to as an equation. For instance, the answer obd + 6 = 12 has an equal sign between the elements ptdc + 6 and 12, respectively. There is a mathematical formula that describes the relationship between two phrases on either side of a letter. Frequently, the symbol and the single variable are the same. For example, 4x – 4 = 0.
Here,
Solving once per variable is the key to this issue.
Let x equal quarters and y equal dimes.
So, x + y = 20
Now, we'll build an equation using the coin values and total quantity of cash. (Decimals have been omitted for clarity.) 25x + 10y = 320
In terms of y, let's restate the original equation: y = 20 - x
In the second equation, we will now substitute this for y. 25x + 10(20-x) = 320
Calculate the value of x: 25x + 200 – 10x = 320.
15x = 120
8 quads times x
In light of this, y = 20 - 8 = 12 pennies.
Therefore , the solution of the given problem of equation comes out to be 12 pennies.

What is the slope of y =- 9?
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.

How do you find the domain and range of a composition of F and G?
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.
So, the range of the given function f(x) = –37 will be y = –37.

1980 (1980 is year zero, 1981 is year one). Approximate a line to represent the data, a slope, a yintercept and equation that models your line of best fit.
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.
