What is the measure of angle R?
A) 17 degrees
B) 25 degrees
C) 34 degrees
D) 65 degrees
The measure of angle R is approximately 91.8 degrees.
How to find the value angle R?We can use the law of cosines to solve for angle R in triangle PQR, since we know the lengths of two sides and the included angle:
\(c^2 = a^2 + b^2 - 2ab cos(C)\)
where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
In this case, we want to solve for angle R, so we'll use c = PR = 36, a = PQ = 20, and b = QR. We can find QR using the Pythagorean theorem, since triangle PQR is a right triangle with right angle at Q:
\(QR^2 = PR^2 - PQ^2\)
\(QR^2 = 36^2 - 20^2\)
\(QR^2 = 776\)
\(QR = \sqrt(776) = 28\sqrt(2)\)
Now we can use the law of cosines to solve for angle R:
\(c^2 = a^2 + b^2 - 2ab cos(C)\)
\(36^2 = 20^2 + (28sqrt(2))^2 - 2(20)(28sqrt(2)) cos(R)\)
\(1296 = 400 + 784 - 1120\sqrt(2) cos(R)\)
\(cos(R) = (400 + 784 - 1296)/(1120\sqrt(2))\)
cos(R) = -0.0271
R = arccos(-0.0271)
R = 91.8 degrees (rounded to one decimal place)
Therefore, the measure of angle R is approximately 91.8 degrees.

Suppose the total time available per month in machining, assembly and inspection departments are 1050, 1160 and 830 hours respectively.
Required:
Determine the number of units of each product to be produced in a month to use up all the available resources (use Gaussaian method)
The company should produce 5 units of Metakeb tractors, 8 units of Mewesson tractors, and 16 units of Metekem tractors in a month to use up all the available resources.
What is equations ?
An equation is a mathematical statement that shows that two expressions are equal. It consists of two expressions separated by an equals sign. For example, 3x + 5 = 14 is an equation that states that the sum of 3 times x and 5 is equal to 14.
Let x, y, and z be the number of units of Metakeb, Mewesson, and Metekem tractors produced, respectively.
Then we have the following system of equations based on the time required in each department:
\(1200x + 1800y + 3000z &\leq 63000 \\&&\text{(machining department)}\2400x + 1200y + 1200z &\leq 69600 \\&&\text{(assembly department)}\600x + 3000y &\leq 49800 \\&&\text{(inspection department)}\)
Converting the hours to minutes, we get:
Machining department: 1050 hours = 63,000 minutes
Assembly department: 1160 hours = 69,600 minutes
Inspection department: 830 hours = 49,800 minutes
We can rewrite the system of equations as follows:
\(20x + 30y + 50z &\leq 1050 &&\text{(machining department)}\\ \\10x + 5y + 5z &\leq 580 &&\text{(assembly department)}\\ \\x + 5y &\leq 83 &&\text{(inspection department)}\\ \\\)
To use Gaussian elimination to solve the system of equations, we first write the augmented matrix:
\(\begin{bmatrix}20 & 30 & 50 & | & 1050 \\10 & 5 & 5 & | & 580 \\1 & 5 & 0 & | & 83\end{bmatrix}\)
Performing row operations to obtain row echelon form:
\(\begin{bmatrix}20 & 30 & 50 & | & 1050 \\0 & -55 & -95 & | & -790 \\0 & 1 & -5/4 & | & -1.35\end{bmatrix}\)
Next, perform additional row operations to get the matrix in reduced row echelon form:
\(\begin{bmatrix}20 & 30 & 50 & | & 1050 \\0 & 1 & 19/55 & | & -14.36 \\0 & 0 & 367/55 & | & 105.36\end{bmatrix}\)
Finally, solve for the variables:
\(z &= \frac{105.36}{367/55} = 16 \\ \\y + \frac{19}{55}z &= 14.36 \\ \\y + \frac{19}{55}(16) &= 14.36 \\ \\y &= 8 \\ \\20x + 30y + 50z &= 1050 \\ \\20x + 30(8) + 50(16) &= 1050 \\ \\20x &= 90 \\ \\x &= 4.5\)
Therefore, the company should produce 4.5 units of Metakeb tractors, 8 units of Mewesson tractors, and 16 units of Metekem tractors in a month to use up all the available resources. Since we cannot produce fractional units, we can round up the values of x and y to obtain a feasible production plan of 5 units of Metakeb tractors and 8 units of Mewesson tractors.

How to find the measure of angles?The angle made between the radius and the tangent at the point of contact on a circle is 90°.
Therefore,
∠D = 90 degrees
∠E = 90 degrees
The diagram ACDE forms a quadrilateral. The sum of angles in a quadrilateral is 360 degrees. Therefore, we have to equate the sum of the quadrilateral angles to 360 degrees.
Hence,
90 + 90 + 2x + 7 + 5x - 2 = 360
180 + 7x + 5 = 360
7x = 360 - 180 - 5
7x = 180 - 5
7x = 175
x = 175 / 7
x = 25
Therefore,
∠A = 5(25) - 2 = 125 - 2 = 123 degrees.

Step-by-step explanation:
From the question we are told that
The Function
\(f(x)=1+\frac{1}{x} +\frac{5}{x^2} +\frac{1}{x^3}\)
Generally the differentiation of function f(x) is mathematically solved as
\(f(x)=1+\frac{1}{x} +\frac{5}{x^2} +\frac{1}{x^3}\)
\(f(x)=\frac{x^3+x^2+5x+1}{x^2}\)
Therefore
\(f'(x)=\frac{x^2+10x+3}{x^4}\)
Generally critical point is given as
\(f'(x)=0\)
\(\frac{x^2+10x+3}{x^4}=0\)
\(x=-5 \pm\sqrt{22}\)
Generally the maximum and minimum x value for critical point is mathematically solved as
\(f'(-5 \pm\sqrt{22})\)
Where
Maximum value of x
\(f'(-5 +\sqrt{22})<0\)
Minimum value of x
\(f'(-5 +\sqrt{22})<0\)
Therefore interval of increase is mathematically given by
\(f'(-5 -\sqrt{22}),f'(-5 +\sqrt{22})\)
\(f(x)<0,-\infty<x<(f'(-5 -\sqrt{22})) ,(f'(-5 +\sqrt{22}))<x<0,0<x< \infty\)
Therefore interval of decrease is mathematically given by
\((-\infty,-5 -\sqrt{22}),f'(-5 +\sqrt{22},0),(0,\infty)\)
Generally the second differentiation of function f(x) is mathematically solved as
\(f''(x)=\frac{2(x^2+15x+6)}{x^5}\)
Generally the point of inflection is mathematically solved as
\(f''(x)=0\)
\(x^2+15x+6=0\)
Therefore inflection points is given as
\(x=\frac{1}{2} (-15 \pm \sqrt{201}\)
\(f''(x)>0,\frac{1}{2}(-15-\sqrt{201}) <x<\frac{1}{2}(-15-\sqrt{201}) <x<0\)
a)Generally the concave upward interval X is mathematically given as
\(X=((-15-\sqrt{201},(-15+\sqrt{201}),(0,\infty)\)
\(f''(x)<0,-\infty<x<\frac{1}{2}(-15-\sqrt{201}) , \frac{1}{2}(-15-\sqrt{201}) <x<0\)
b)Generally the concave downward interval Y is mathematically given as

What is the area of the square that measures 3.1 m on each side
The area of the square with a side length of 3.1 meters is 9.61 square meters.
To find the area of a square, we need to multiply the length of one side by itself. In this case, the square has a side length of 3.1 m.
Area of a square = side length × side length
Substituting the given side length into the formula:
Area = 3.1 m × 3.1 m
To perform the calculation:
Area = 9.61 m²
It's worth noting that when calculating the area, we are working with squared units. In this case, the side length is in meters, so the area is expressed in square meters (m²). The area represents the amount of space enclosed within the square.
Remember, to find the area of any square, you simply need to multiply the length of one side by itself.
The area of the square with a side length of 3.1 meters is 9.61 square meters.

A university has raised $6,000 for a new scholarship fund. A university trustee offers to match the donation up to 30% if the university can raise $5,000 more for the fund. If the university is able to raise the extra amount, how much money will be in the fund after the trustee's donation?
Answer:
$14300
Step-by-step explanation:
30% is the same as .3
They are raising 5k more to the 6k so 5000+6000= 11000
.3*11000= 3300...so the trustee is adding 3300 to the fund, making the total fund 3300+11000= $14300

Step-by-step explanation:
In dilation, two figures have same shape but different size.
The triangular prism was dilated to create a new prism.
The larger triangular prism is the original shape
The smaller triangular prism is the new shape
Let the scale factor = p
For larger prism: the length = breadth = height = 10unit
For smaller prism: the length = breadth = height = 8unit
Surface area of smaller triangular prism = p × surface area of larger triangular prism
p = (Surface area of smaller triangular prism)/(surface area of larger triangular prism)
In similar shapes, the ratio of their areas = square of the ratio of their corresponding sides.
Let's take the height of each shape
Ratio of their corresponding sides (height) = 8/10

Answer:
f(x) = 0.5x
Step-by-step explanation:
For this problem, we simply have to find the constant of proportionality between x and f(x). In other words, what x is multiplied by to get f(x).
Since this proportion is constant (meaning it doesn't change), all we have to do is divide an f(x) value in the table by its corresponding x value.
p = f(x) / x
p = -2 / -4
p = 1/2 = 0.5
We can show the relationship of x to f(x) with the equation f(x) = px, which can be simplified using the constant of proportionality that we just solved for.
f(x) = 0.5x
