The required values of given the trigonometric functions are sin(A + B) = -100/2501 and sin(A - B) = -980/2501.
What are Trigonometric functions?Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.
We have been given that the trigonometric function
sin (A) = -60/61 and cos(B) = 9/41
So cos (A) = √1 - (-60/61)² = 11/61, and sin(B) = √1 - (9/41)² = 40/41
To compute the trigonometric functions sin(A + B) and sin(A - B)
⇒ sin(A + B) = sinA cosB + cos A sinB
⇒ sin(A + B) = (-60/61)(9/41) + (11/61)(40/41)
⇒ sin(A + B) = -540/2501 + 440/2501
⇒ sin(A + B) = -100/2501
⇒ sin(A - B) = sinA cosB - cos A sinB
⇒ sin(A - B) = (-60/61)(9/41) - (11/61)(40/41)
⇒ sin(A - B) = -540/2501 - 440/2501
⇒ sin(A - B) = -980/2501
Thus, the required values of given the trigonometric functions are sin(A + B) = -100/2501 and sin(A - B) = -980/2501.

what is the measure of ZXY in the figure below
we get that
[tex]5x+3x=180\rightarrow8x=180\rightarrow x=\frac{180}{8}=22.5[/tex]so the angle ZXY is:
[tex]\angle ZXY=3\cdot22.5=67.5^{\circ}[/tex]2. In the 1936 US presidential election polls, the Literary Digest held a poll that forecast that Alfred E. Landon would defeat Franklin Delano Roosevelt by 57% to 43%. They had used lists of telephone and automobile owners to select their sample. George Gallup, using a much smaller sample (300,01 rather than 2,000,000) , predicted Roosevelt would win, and he was right. What went wrong with the Literary Digest poll?
Explanation
We can infer that the Literary Digest poll was wrong because it was biased.
We are told that the poll used lists of telephone and automobile owners to select their sample which doesn't give a full representation of all those who will vote in the election.
So we can infer that the problem with the Literary Digest poll is that it was Biased
A sculptor is planning to order a rectangular of composite stone to sculpt a lion. The sculptor anticipated that the lion will be 5 feet long, about 2 feet wide and at the tallest part of the lions body, have a height of 3.5 feet. The composite stone weighs 40 pounds per cubic foot. To the nearest cubic foot, estimate the weight of the smallest rectangular block that the sculptor must purchase in order to create his statue
In order to sculpt the lion, the scupltor must have, at least, a rectangular composite that has the maximum dimensions of the final sculpture.
Thereby,
[tex]5ft\cdot2ft\cdot3.5ft=35ft^3[/tex]The rectangular composite would need to have a volume of 35 cubic feet.
Now, let's use a rule of three to calculate the weight of the composite, since we're given its density:
This way,
[tex]x=\frac{35\cdot40}{1}\rightarrow1400lbs[/tex]We can conclude that the weight of the smallest rectangular block that the sculptor must purchase in order to create his statue is 1400 lbs
in the figure above what is the value of X what is the measure is side WZ
Based on the diagram, we have two right triangles. These are triangle WYT and triangle WYZ.
Since both legs of each triangle is congruent to each other, we can also say that their hypotenuse are congruent too.
Thus, TW = WZ or 2x = 3x - 5.
From this, we can now solve for x.
[tex]\begin{gathered} 2x=3x-5 \\ \text{Subtract 3x on both sides.} \\ 2x-3x=3x-3x-5 \\ -x=-5 \\ \text{Divide by -1 on both sides.} \\ x=5 \end{gathered}[/tex]Therefore, the value of x = 5.
To solve for WZ, let's plug in x = 5 to 3x - 5.
[tex]\begin{gathered} WZ=3x-5 \\ WZ=3(5)-5 \\ WZ=15-5 \\ WZ=10 \end{gathered}[/tex]Therefore, WZ = 10.
To summarize, x = 5 and WZ = 10. (Option A)

How do I graph this?
Answer:
See below
Step-by-step explanation:
Create a linear equation that satisfies conditions.Type your equation in the form y = mx + b if a value is not an integer then type it in as a decimal rounded to the nearest hundredth.
Solution
Part a
For the first part we have two points (2,4) and (4,10)
We can find the slope like this:
[tex]m=\frac{10-4}{4-2}=\frac{6}{2}=3[/tex]And then the intercept would be:
4= 3*2 +b
b= 4-6= -2
Then the answer is:
y= 3x -2
Part b
f(-4)=18 and f(4) =2
The slope is:
[tex]m=\frac{18-2}{-4-4}=-2[/tex]
2= -2*4 +b
b= 2+8=10
y= -2x+10
Part c
x intercept at (-5,0) and the y intercept (0,4)
[tex]m=\frac{4-0}{0+5}=\frac{4}{5}[/tex]And using the y intercept we have:
4= 4/5*0 +b
b= 4
y= 4/5x +4
Amanda has scored 24,22,27,23 and 30 points in her five basketball games so far. How many points does she need to score in her next game so that her average (mean) is 25 points per game?
To answer this question, we need to remember that the mean of a data is the sum of the data divided by the total number of elements that represent this data.
Therefore, if we need to find the sixth value for which the average (mean) per game is 25 points, we can proceed as follows:
[tex]\frac{24+22+27+23+30+x}{6}=25[/tex]Now, to find the value, x, we need to follow the next steps:
1. Add the values in the numerator of the fraction:
[tex]\frac{126+x}{6}=25[/tex]2. Multiply both sides by 6:
[tex]\begin{gathered} \frac{6\left(126+x\right?}{6}=6\left(25\right? \\ \frac{6}{6}\left(126+x\right?=150 \\ 126+x=150 \end{gathered}[/tex]3. Finally, subtract 126 from both sides of the equation:
[tex]\begin{gathered} 126-126+x=150-126 \\ x=24 \end{gathered}[/tex]Therefore, the value she needs is 24 points.
And we can check this value as follows:
[tex]\frac{24+22+27+23+30+24}{6}=\frac{150}{6}=25[/tex]Therefore, in summary, we have that Amanda needs to score 24 points in the next game so that her average is 25 points per game.

What are permutations?
A permutation of a set in mathematics is a loosely defined organization of its members into a sequence or linear order, or, if the set is already sorted, a rearranging of its elements. The act or process of shifting the linear order of an ordered set is often referred to as "permutation." Permutations are distinct from combinations, which are random picks of certain members of a collection. For example, there are six permutations of the set 1, 2, 3 represented as tuples: (1, 2, 3), (1, 3, 2), (2, 1, 3), (2, 3, 1), (3, 1, 2), and (3, 1, 2). (3, 2, 1).
