Determine values that would make f ( x ) = 3 − x x 2 − 4 equal 0.
The value x = 3 would make the function f(x) equal to 0.
How to determine the values that would make f ( x ) = 3 − x x 2 − 4 equal 0.To determine the values that would make the function f(x) = (3 - x)/(x^2 - 4) equal to 0, we set the numerator equal to 0 since a fraction is equal to 0 when its numerator is equal to 0.
So we solve the equation:
3 - x = 0
Solving for x, we find:
x = 3
Therefore, the value x = 3 would make the function f(x) equal to 0.

A company is tracking a number of complaints received on its website. During the first 4 months, they
record the following numbers of complaints: 18, 22, 26, 30. What is the explicit rule for the number of
complaints they will received in the nth month? After how many months will the complaints reach 126?
To find the explicit rule for the number of complaints received in the nth month, we can observe the pattern in the given data. The number of complaints increases by 4 each month.
So, we can write the explicit rule as follows:
Number of complaints (n) = 18 + 4(n - 1)
To find the number of months it will take for the complaints to reach 126, we can set up an equation:
18 + 4(n - 1) = 126
Simplifying the equation:
4(n - 1) = 126 - 18
4(n - 1) = 108
n - 1 = 27
n = 28
Therefore, it will take 28 months for the number of complaints to reach 126.

The length of one side of the equilateral triangle in terms of x is 6x.
To find the length of one side of the equilateral triangle in terms of x, we need to consider the perimeter of both the rectangle and the equilateral triangle.
The perimeter of a rectangle is given by the formula:
Perimeter of rectangle = 2(length + width)
In this case, the length of the rectangle is 7x cm, and the width is 2x cm. Substituting these values into the formula, we have:
Perimeter of rectangle = 2(7x + 2x) = 2(9x) = 18x
We are told that the equilateral triangle has the same perimeter as the rectangle.
Since an equilateral triangle has all sides equal, the perimeter can be calculated by multiplying the length of one side by 3.
Therefore, we have:
Perimeter of equilateral triangle = 3(side length)
Since the perimeter of the equilateral triangle is equal to the perimeter of the rectangle (18x), we can set up the equation:
3(side length) = 18x
Dividing both sides of the equation by 3, we get:
side length = 6x
Hence, the length of one side of the equilateral triangle in terms of x is 6x.

Jane is fencing in her backyard. The yard is a rectangular area where one side is the back of her house. The fence will go around only the other 3 sides. The side opposite the house is the same length as the house, which is 25 feet. Jane will use 120 feet of fencing.
Which equation can Jane use to decide how long each of the other two sides of her fence can be?
Answer: Jane can use the equation x = 47.5.
Step-by-step explanation:
From the given information, we know that one side opposite the house is 25 feet, and Jane will use a total of 120 feet of fencing. Since the fence goes around the other three sides of the yard, the combined length of the other two sides will be equal to 120 - 25 = 95 feet.
To determine the length of each of the other two sides, we can set up an equation:
2x = 95
The factor of 2 appears because there are two sides of equal length. By summing up the lengths of the other two sides, we obtain 2x.
Simplifying the equation, we have:
x = 95 / 2
x = 47.5

A(-1, 2), B(3, 5) and C(4, 8) are the vertices of triangle ABC. Forces whose magnitudes are 5N and 3√10N act along vectors AB and CB respectively. Find the direction of the resultant of the forces.
The direction of the resultant of A(-1, 2), B(3, 5) and C(4, 8) are the vertices of triangle ABC, forces is [tex]$2\sqrt{3}$[/tex] radians.
Given, A(-1, 2), B(3, 5) and C(4, 8) are the vertices of triangle ABC, and forces whose magnitudes are 5N and 3√10N act along vectors AB and CB respectively.
We need to find the direction of the resultant of the forces.
Therefore, let's solve this by using the parallelogram law of forces which states that:
If two forces acting simultaneously at a point are represented in magnitude and direction by the adjacent sides of a parallelogram drawn from the point, then their resultant is represented in magnitude and direction by the diagonal of the parallelogram passing through that point.
From the above, the adjacent sides of a parallelogram drawn from point B can be represented as `AB` and `BC`.
Therefore, the diagonal of the parallelogram passing through B represents the magnitude and direction of the resultant of the two forces acting at point B.
Therefore, we first need to determine the position vector of points A, B, and C.
i.e. position vector of point A:
[tex]\vec{A} = \begin{bmatrix}-1\\2\end{bmatrix}$$Position vector of point `B`:$$\vec{B} = \begin{bmatrix}3\\5\end{bmatrix}$$[/tex]
Position vector of point C:
[tex]$$\vec{C} = \begin{bmatrix}4\\8\end{bmatrix}$$[/tex]
We know that the force acting along vector `AB` is 5 N and along vector `CB` is `3√10` N.
Let the angle between the vectors `AB` and `BC` be `θ`.
We know that,
[tex]$$\text{Magnitude of the resultant of the forces} = \sqrt{(5)^2 + (3√10)^2 + 2(5)(3√10)\cos(θ)}$$[/tex]
And direction of the resultant of the forces `θ` can be given by
[tex]$$\tan(θ) = \frac{5(3√10)\sin(θ)}{5^2 + (3√10)^2 + 2(5)(3√10)\cos(θ)}$$[/tex]
Substitute the values of the magnitude of the resultant of the forces and find the value of θ.
The resultant of the forces can be represented in the magnitude and direction as:
[tex]$$\vec{R} = \begin{bmatrix}3\\5\end{bmatrix} - \begin{bmatrix}-1\\2\end{bmatrix} + \begin{bmatrix}4\\8\end{bmatrix} = \begin{bmatrix}6\\11\end{bmatrix}$$[/tex]
Therefore, the direction of the resultant of the forces is [tex]$2\sqrt{3}$[/tex] radians.

The area of the larger square is equal to the sum of the areas of the two smaller squares. In image 3, the smaller squares are replaced by rectangles with the same areas, and in image 4 these rectangles are rearranged to form the same square as in image 2.
1. Image 2A. Image 2 is formed by rotating image 1, that is, the angle and lengths of the legs stay the same, only the position of the triangle changes.
Image 2 is formed from image 1 by rotating the right-angled triangle clockwise about point B through the angle of 90°. B. The lengths of the triangle in image 2 are related to the lengths of the triangle in image 1 through the Pythagorean Theorem.
In image 1, a = 4 and b = 3, so [tex]c^2 = a^2 + b^2 = 4^2 + 3^2 = 16 + 9 = 25[/tex]. Thus, c = 5.
Since image 2 is just a rotation of image 1, the lengths of the sides remain the same, that is, a = 4, b = 3, and c = 5. C. The length of the hypotenuse of the triangle in image 2 is c = 5, which is the same as the hypotenuse of the triangle in the image.
1. This verifies the Pythagorean Theorem, which states that the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse.
That is, [tex]a^2 + b^2 = c^2[/tex]; where a, b, and c are the lengths of the legs and hypotenuse of the triangle.
2. The visual proof demonstrates the Pythagorean Theorem by showing that the sum of the areas of the squares constructed on the legs of a right triangle is equal to the area of the square constructed on the hypotenuse of the triangle.
Image 2 shows a right triangle with legs of length 3 and 4 units and a hypotenuse of length 5 units. Squares are constructed on each of the sides of the triangle, and the areas of these squares are compared.
The smaller squares on the legs of the triangle have areas of 9 and 16 square units, respectively, while the larger square on the hypotenuse of the triangle has an area of 25 square units.
Thus, the area of the larger square is equal to the sum of the areas of the two smaller squares. In image 3, the smaller squares are replaced by rectangles with the same areas, and in image 4 these rectangles are rearranged to form the same square as in image 2. This demonstrates that the Pythagorean Theorem holds true for all right triangles.

In a right triangle ABC, where angle C is the right angle, the cosine of angle A is equal to option C: cos B.
How to Find Cosine of an Angle of a Right Triangle?Using the definition of cosine, we can express the cosine of angle A in the right triangle as cos(A) = adjacent side / hypotenuse, which is BC / AC.
Considering angle B, it is the complementary angle to angle A. Since the sum of the angles in a triangle is 180 degrees, we have angle A + angle B + angle C = 180 degrees.
Angle C is 90 degrees, we can rewrite it as angle A + angle B + 90 degrees = 180 degrees, which simplifies to angle A + angle B = 90 degrees.
By rearranging the equation, we get angle B = 90 degrees - angle A.
Now, we can substitute angle B in the cosine expression: cos(A) = adjacent side / hypotenuse = BC / AC = cos(B).
Therefore, cos(A) is equal to cos(B), corresponding to option C.

Answer:
B) sin (90° - A)
Step-by-step explanation:
In a right triangle ABC, we are told that angle C is the right angle.
As C = 90°, and since the interior angles of a triangle sum to 180°, the other two angles, A and B, are complementary angles (sum to 90°). Therefore:
A = 90° - BB = 90° - AThe sine and cosine of complementary angles have a special relationship. For two complementary angles, the cosine of one equals the sine of the other. So for our right triangle ABC, the cosine of A equals the sine of B, and the cosine of B equals the sine of A:
cos A = sin Bcos B = sin ASubstituting B = 90° - A, we can say that:

a circular wheel of diameter 35 cm makes 100 revolutions in 1 min. calculate the distance covered by the wheel in half an hour. Answer in km
Take pie= 22/7
Answer ASAP
Answer: To calculate the distance covered by the wheel in half an hour, we need to determine the total number of revolutions the wheel makes in that time and then convert it to the distance covered.
Given:
Diameter of the wheel = 35 cm
Radius of the wheel = Diameter/2 = 35/2 = 17.5 cm = 0.175 m (converting to meters)
Number of revolutions in 1 minute = 100
First, let's calculate the circumference of the wheel:
Circumference = 2 * π * radius
Using the value of π as 22/7:
Circumference = 2 * (22/7) * 0.175
Circumference = 1.1 m
Now, we can find the number of revolutions the wheel makes in half an hour:
Number of revolutions in 30 minutes = 100 revolutions/minute * 30 minutes
Number of revolutions in 30 minutes = 3000 revolutions
Finally, we can calculate the distance covered by the wheel:
Distance covered = Circumference * Number of revolutions
Distance covered = 1.1 m * 3000
Distance covered = 3300 m
Converting the distance to kilometers:
Distance covered = 3300 m / 1000 = 3.3 km
Therefore, the wheel covers a distance of 3.3 km in half an hour.

Calculate the area of the trapezium.
10 cm
9 cm
8 cm
Not to scale
Answer:To calculate the area of a trapezium, we need the lengths of its parallel sides (the bases) and the distance between them (the height). Given that the trapezium is not to scale, we assume the 10 cm, 9 cm, and 8 cm measurements refer to the lengths of the three sides.
Let's label the trapezium as ABCD, where AB is the longer base, CD is the shorter base, and AD and BC are the non-parallel sides.
Given:
AB = 10 cm (longer base)
CD = 8 cm (shorter base)
AD = 9 cm (non-parallel side)
To calculate the area of the trapezium, we can use the formula:
Area = (1/2) * (AB + CD) * height
However, the height is not given directly. We can calculate it using the Pythagorean theorem by considering triangle ADB.
Using the Pythagorean theorem, we have:
AD^2 = AB^2 - BD^2
Rearranging the equation to solve for BD:
BD^2 = AB^2 - AD^2
BD^2 = 10^2 - 9^2
BD^2 = 100 - 81
BD^2 = 19
BD = √19 cm (approx.)
Now that we have BD, we can use it as the height of the trapezium.
Area = (1/2) * (AB + CD) * height
Area = (1/2) * (10 + 8) * √19
Area = (1/2) * 18 * √19
Area = 9 * √19 cm² (approx.)
Therefore, the area of the trapezium is approximately 9√19 cm².

Use trigonometry to solve for the missing angle.
Answer:
71.8962°
Step-by-step explanation:
In order to find the angle given 2 sides, you need to identify the 2 sides with the given measure.
Since we need to find X, the 2 sides are 52 (the opposite side) and 17 (the adjacent side)
The only way to find X with an opposite and adjacent side is by using tan.
In order to find the angle, you will need to use the tan^-1 (52/17)
That will give you 71.8962°
Answer:
x = 71.9°
Step-by-step explanation:
The given diagram shows a right triangle with an unknown angle, x.
We have been given the measures of the sides that are opposite and adjacent the unknown angle. Therefore, we can use the tangent trigonometric ratio to find the value of x.
[tex]\boxed{\begin{minipage}{7 cm}\underline{Tangent trigonometric ratio} \\\\$\sf \tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle.\\\end{minipage}}[/tex]
The unknown angle is x, so θ = x.
The side opposite the angle measures 52 units, so O = 52.
The side adjacent the angle measures 17 units, so A = 17.
Substitute the values into the ratio and solve for x:
[tex]\tan x=\dfrac{52}{17}[/tex]
[tex]x=\tan^{-1}\left(\dfrac{52}{17}\right)[/tex]
[tex]x=71.8962369...[/tex]
[tex]x=71.9^{\circ}\; \sf (nearest\;tenth)[/tex]
Therefore, the value of x is 71.9°.
