What is a set theory?The study of sets, which are collections of objects, is a topic covered by the mathematical field known as set theory. A set is a clearly defined group of unique items, sometimes referred to as its elements or members, in set theory.
Let's use the inclusion-exclusion principle to compute the number of elements in the union of four sets:
First, we add up the sizes of the individual sets:
4 x 15 = 60
Next, we subtract the sizes of the pair-wise intersections:
6 x 5 = 30
We have to multiply by 6 because there are 6 pairs of sets.
Now we need to add back the sizes of the three-way intersections:
4 x 2 = 8
We have to multiply by 4 because there are 4 triples of sets.
Finally, we need to subtract the size of the intersection of all four sets:
-1
Putting it all together, we have:
60 - 30 + 8 - 1 = 37
Therefore, the size of the union is 37.

m∠W = 33.8° , using inverse trignometric ratio.
What do you mean by inverse trignometric functions?
The sine, cosine, tangent, cotangent, secant, and cosecant functions are the fundamental trigonometric functions. Inverse trigonometric functions are just the inverse functions of these functions. They can also be referred to as cyclometric functions, antitrigonometric functions, or arcus functions. Trigonometry's inverse functions are used to find the angle for any trigonometric ratio.
It is given that VU = 2 units and VW = 3 units and VUW is a right angle triangle , right angled at V.
Using the ratio of tanW,
As we know tanA = P/B where P is the perpendicular and B is the base
In the given triangle VUW,
tanW = VU/VW = 2/3
W = [tex]tan^{-1}[/tex](2/3) = [tex]tan^{-1}[/tex](0.67) = 33.8 degree
Therefore, m∠W = 33.8°

What is fraction?Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English. A fraction only informs us of the number of components that make up the total. The slash that is inserted between the two numbers identifies a fraction. The numerator is the highest number, while the denominator is the lowest number. 1/2, for instance, is a fraction. A fraction is a number that is a component of a whole.

The required equation of the line is y = (7/4)x + 2.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The given coordinate of the point on the line is ; (-4, -5) and the slope is 7/4
Let the required equation of the line is
⇒ y - y₁ = m [x -x₁]
x₁ = -4, y₁ = -5 and m = 7/4
Substitute values in the equation, we get
y - (-5)= (7/4)(x - (-4))
y + 5 = (7/4)(x + 4)
y + 5 = (7/4)x + (7/4)4
y = (7/4)x + 7 - 5
y = (7/4)x + 2

Richard's Bakery recently spent a total of $594 on new equipment, and their average hourly operating costs are $5. Their average hourly receipts are $23. The bakery will soon make back the amount it invested in equipment. How many hours will that take? What would the total expenses and receipts both equal?
Answer:
33 Hours.
Step-by-step explanation:
Their hourly receipts are $23, and their hourly operating costs are $5. So you would subtract the hourly receipts from the hourly operating costs.
23 - 5 = 18
Then you would take the new number and divide the money spent on equipment by the money earned an hour.
594 / 18 = 33

Let sin A = 1/3, with A in quadrant II, and let cos B =3/4, with B in quadrant I. Find sin(A - B). Give an exact, simplified answer.
The Trigonometric function sin(A - B) = (3 - 2[tex]\sqrt{14}[/tex]) ÷ 12
What is trigonometry?The study of correlations between triangles side lengths and angles is known as trigonometry.In geometric figures, unknown angles and distances are derived from known or measured angles using trigonometric functions. The need to calculate angles and distances in disciplines like astronomy, mapmaking, surveying, and artillery range finding led to the development of trigonometry.The easiest way is to use the Pythagorean Identity to find both cos A and sin B. Then use the sum/difference angle identity for sine.
The trigonometric Pythagorean identity tells us that,
[tex]Sin^{2}[/tex]θ + [tex]cos^{2}[/tex]θ = 1
which follows directly from the geometric identity for right triangles and the fact that,
sinθ = y/r and cosθ = x/r
If r is the distance (x,y) is from the origin, then
[tex]x^{2}[/tex] + [tex]y^{2}[/tex] = [tex]r^{2}[/tex]
[tex](x/r)^{2}[/tex] + [tex](y/r)^{2}[/tex] = 1(divide both sides by [tex]r^{2}[/tex])
[tex]cos^{2}[/tex]θ + [tex]Sin^{2}[/tex]θ = 1
Anyway, if we know sin A (and which quadrant it ends in), we can solve for cos A and vice versa:
[tex]Sin^{2}[/tex]θ + [tex]cos^{2}[/tex]θ = 1
[tex](1/3)^{2}[/tex] + [tex]cos^{2}[/tex]θ = 1
⇒ cos A = [tex]\sqrt{1-(1/3)^{2} }[/tex] = [tex]\frac{2\sqrt{2}}{3}[/tex]
cosθ is always negative in this quadrant.
Therefore,
cos A = -[tex]\frac{2\sqrt{2} }{3}[/tex]
Similar reasoning can be done with cos B = [tex]\frac{3}{4}[/tex] to show that sin B = -[tex]\frac{\sqrt{7} }{4}[/tex]
Now that we have all the necessary elements, we can use the sum/difference angle identity:
Sin(A-B) = sin A cos B - cos A sin B
= ( [tex]\frac{1}{3}[/tex] × [tex]\frac{3}{4}[/tex] ) - ( (-[tex]\frac{2\sqrt{2} }{3}[/tex] ) × (-[tex]\sqrt{7[/tex]/4) )
= (3 ÷ 12) - (2[tex]\sqrt{14}[/tex] ÷ 12)
= (3 - 2[tex]\sqrt{14}[/tex]) ÷ 12
We get sin(A - B) = (3 - 2[tex]\sqrt{14}[/tex]) ÷ 12

total of 64 pounds of grapes and apples. Determine the number of pounds of grapes
sold and the number of pounds of apples sold.
The number of pounds of grapes is 24 sold and the number of pounds of apples sold is 30.
Given that,
Apples and grapes are sold at Arianys' farm stand. The price per pound for apples is $4 while the price per pound for grapes is $3.75. 64 pounds of apples and grapes were sold for a total profit of $251.75 for Arianys.
We have to find the number of the sold apples and pounds of grapes should be calculated.
What are the equation?a declaration that two mathematical expressions' values are equal (represented by the symbol =).
We get the equations as,
3.75x+4y=251.75
y=-0.93x+62.93---->equation(1)
x+y=64
y=-x+64------>equation (2)

8. Use point-slope form to write the equation of a line that passes through the point (18, -3) with slope -1.
The equation of the line that passes through the point (18,-3) with slope -1 is y = -x+15.
According to the question,
We have the following information:
The line passes through the point (18,-3) with slope -1.
We know that the following formula is used to find the equation of the line passing through a point with the slope which is denoted by m:
(y-y') = m(x-x')
In this case, we have the following values:
m = -1
x' = 18 and y' = -3
Putting these values in the above formula:
y-(-3) = -1(x-18)
y+3 = -x+18
Subtracting 3 from both sides of the equation:
y = -x+18-3
y = -x+15
Hence, the equation of the line that passes through the point (18,-3) with slope -1 is y = -x+15.

13 points) find the area of the largest rectangle that can be inscribed in a right triangle with legs of length 3 and 4 if two sides of the rectangle lie along the legs
The area of the largest rectangle will be 3.
By using properties of similar triangles we can say that
[tex]\frac{EF}{FB} - \frac{AC}{CB}[/tex]
B / (3 - a) = 4/3
3b = 12 - 4a
4a = 12 - 3b
a = (12 - 3b) / 4
Now as we know area of a rectangle is length * width. let us find the area
A = l * w
A = b * ( (2 - 3b) / 4 )
A = 3b - 3[tex]b^{2}[/tex]/4
Now to find maximum value we will differentiate the area and put it equal to zero.
[tex]D^{1}[/tex] = 3 - 6b/4 = 0
6b/4 = 3
6b = 12
b = 2

What is rounding decimals?
The term "rounding decimals" describes the accurate rounding of decimal figures. To the nearest whole, tenth, or hundredth, we can round decimals.
The next place value on the right should be used to round a number to the closest tenth (the hundredths). Simply take away all the digits to the right if it's 4 or fewer. Remove all the digits to the right after adding 1 to the digit in the tenth position if the number is 5 or above.
We need to find the value that rounds to the nearest tenth which results in 56.8
Now, we check all options one by one and rounded them to the nearest tenth
56.85 = 56.9 (rounded to the nearest tenth)
56.809 = 56.8 (rounded to the nearest tenth)
56.749 = 56.7 (rounded to the nearest tenth)
