What do you mean by sine?The sine function is a basic trigonometric function used in mathematics to describe the relationship between the lengths of sides of a right triangle and its angles. The sine function is denoted by the symbol sin and is defined as the ratio of the side opposite a given angle to the hypotenuse of the triangle.
The sine function is periodic, meaning that it repeats its values over a certain interval, and its values range from -1 to 1.
If sin (θ)=8/17, where 0 < θ < pi/2 and cos (θ)=5/13, then θ can be found using the inverse sine function.
θ = sin⁻¹ (8/17) = sin⁻¹ (5/13) = arctan(8/5).
So, the value of θ is approximately equal to 0.92729522.

determine whether the set s spans r3. if the set does not span r3, then give a geometric description of the subspace that it does span. s = {(6, 7, 1), (−3, 4, 7), (1, −3, 4)}
The set S = {(6, 7, 1), (−3, 4, 7), (1, −3, 4)} spans R³
For (x, y, z) ∈ R³, we can find scalars a, b, c for which the equation
(x, y, z) = a(6, 7, 1) + b (−3, 4, 7) + c (1, −3, 4) is true.
We can write above equation (x, y, z) = a(6, 7, 1) + b (−3, 4, 7) + c (1, −3, 4) as system of equations,
6a - 3b + c = x
7a + 4b - 3c = y
a + 7b + 4c = z
Above system of equations in matrix form as,
[tex]\begin{bmatrix}6 & -3 & 1 \\7 & 4 & -3 \\1 & 7 & 4\end{bmatrix}\begin{bmatrix}a\\b \\c\end{bmatrix}=\begin{bmatrix}x \\y \\z\end{bmatrix}[/tex]
The determinant of coefficient matrix is,
[tex]\left|\begin{matrix}6 & -3 & 1 \\7 & 4 & -3 \\1 & 7 & 4\end{matrix}\right|=360[/tex]
Since the determinant of the coefficient matrix is not zero (it equals 360), the coefficient matrix is invertible.

Three large cones hang from the ceiling in an office building in front of a bank of windows. The height of each cone is 12 feet and the circumference of the base of each cone is 8π feet. The base and 50% of the lateral surface of each cone is painted red, and the rest of each cone is painted black.
What is the total surface area painted black? Use π≈3.14.
Enter your answer, rounded to the nearest tenth, in the box.
The total surface area painted black is 12.6 sq. feet.
Solving for the total surface area painted black we have: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:
(100% - 75%) * A
= 25% * A
= 25% * 50.265
= 12.566
Rounding to the nearest tenth, the total surface area painted black is 12.6 sq. feet.

The lesson I'm taking explains this one, but I don't understand it. Here are the steps in the example:
The function sin(x-y)/cosec(x+y)=sin²x-sin²y
What is Trigonometry?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

Assume that the int variables a, b, c, and low have been properly declared and initialized.

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.

Find the ymmetric equation of the line that pae through the point P(−2,1,0)
and i parallel to the vector v⃗ =⟨0,2,−3⟩
x + 2 = -2y + 2
y - 1 = 2z + 2
z - 3 = 3x + 6
This is the symmetric equation of the line that passes through the point P and is parallel to the vector .
What is symmetric equation?
A line that passes through the point P and is parallel to the vector v can be represented by the parametric equation:
x = -2 + 0t
y = 1 + 2t
z = 0 - 3t
where t is a scalar parameter. To find the symmetric equation of this line, we need to convert the parametric equation to a normal form. We'll start by finding a point on the line other than P, then use those two points to find the direction vector of the line. Let's use t = 1, then the line passes through the point Q(-2 + 01, 1 + 21, 0 - 3*1) = (-2, 3, -3). The direction vector of the line is found by subtracting the position vectors of P and Q:
d = Q - P = (-2 - (-2), 3 - 1, -3 - 0) = (0, 2, -3) = v
So, the direction vector and the vector v are equal, which means the line is parallel to v. Now we have two points on the line, P and Q, which we can use to find the symmetric equation of the line:
(x + 2)/0 = (y - 1)/2 = (z + 3)/(-3) = t
x + 2 = -2t
y - 1 = 2t
z + 3 = 3t
Rearranging the above equations, we get:
x = -2 - 2t
y = 2t + 1
z = 3t - 3
Since t is a scalar parameter, it can be eliminated from the equations to obtain the symmetric equation of the line:

Write the equation of AB in slope intercept form. Then check whether c lies on ab by substituting the coordinates of point c into the equation
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.

The measure of each angle are 94.2° and 85.8°.
How to detemine the measure of each angleLet'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°.

below is the graph of y=1/x^2. Transform to make it the graph of y=1/(x-2)^2 +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.

Inga is solving 2x2 + 12x – 3 = 0. Which steps could she use to solve the quadratic equation? Select three options. 2(x2 + 6x + 9) = 3 + 18 2(x2 + 6x) = –3 2(x2 + 6x) = 3 x + 3 = Plus or minus StartRoot StartFraction 21 Over 2 EndFraction EndRoot 2(x2 + 6x + 9) = –3 + 9
By completing squares, we will see that the solutions of the given quadratic equation are:
x = -3 ± √(21/2)
How to solve the quadratic equation?
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
x = -3 ± √(21/2)

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.
