prove the identity cos(x-y)-cos(x+y)=2sinxsiny
Answer:
see the procedure
Step-by-step explanation:
we know that
[tex]cos(X - Y) = cosX cosY + sinX sinY\\cos(X + Y) = cosX cosY - sinX sinY[/tex]
so
[tex]cos(X - Y)-cos(X + Y)=cosX cosY + sinX sinY-(cosX cosY - sinX sinY)[/tex]
[tex]cos(X - Y)-cos(X + Y)=cosX cosY + sinX sinY-cosX cosY + sinX sinY[/tex]
[tex]cos(X - Y)-cos(X + Y)=sinX sinY+ sinX sinY[/tex]
[tex]cos(X - Y)-cos(X + Y)=2sinX sinY[/tex] ----> is verified

Ms. Reynolds has a system of 10 sprinklers that water her entire lawn. The sprinklers run one at a time, and each runs for the same amount of time. The first 4 sprinklers run for a total of 50 minutes. How long does it take to water her entire lawn?
*please explain how you got the answer if possible*
Final answer:
To water the entire lawn with 10 sprinklers, each running for the same amount of time, it will take a total of 125 minutes.
Explanation:
Ms. Reynold's system of sprinklers is designed to run sequentially, with each sprinkler getting an equal duration of run time. We know that the first 4 sprinklers run for a total of 50 minutes.
To find out how long one sprinkler runs, we divide the total time of 50 minutes by the number of sprinklers that have run, which is 4:
50 minutes ÷ 4 sprinklers = 12.5 minutes per sprinkler.Now that we know each sprinkler runs for 12.5 minutes, we can calculate the total time to run all 10 sprinklers by multiplying the time per sprinkler by the total number of sprinklers:
12.5 minutes per sprinkler × 10 sprinklers = 125 minutes.Therefore, it will take 125 minutes to water her entire lawn using all 10 sprinklers.

How many 4-letter code words can be made using the letters in the word pencil if : (a) Repetitions are permitted?
Final answer:
The total number of code words is 6 x 6 x 6 x 6, which is 1296 possible code words.
Explanation:
To determine how many 4-letter code words can be made using the letters in the word 'pencil' with repetitions permitted, we consider that each position in the 4-letter code word can be filled by any of the 6 letters from the word 'pencil'. Therefore, for each position, there are 6 choices.
Using the fundamental counting principle, the total number of possible 4-letter code words given that repetitions are allowed is calculated as follows:
First position: 6 possibilitiesSecond position: 6 possibilitiesThird position: 6 possibilitiesFourth position: 6 possibilitiesThus, the total number of code words is 6 x 6 x 6 x 6, which is 1296 possible code words.

In a sale, normal prices are reduced by 20%. The sale price of a shirt is £26. Calculate the normal price of the shirt
The original price of the shirt before the 20% discount was £32.50.
Explanation:In your question, you've stated that a shirt was bought at a sale price of £26, after a reduction of 20%. Therefore, the 20% reduction is equivalent to the difference between the original price and the sale price. To find the original price, we need to understand that the £26 is 80% of the original price as 100% (the original price) minus the 20% reduction equals 80%. So, we can set up the equation as follows:
0.80(x) = 26
To find the value of x (the original price), we divide both sides of the equation by 0.80
x = 26 ÷ 0.80
Therefore, the original price of the shirt was £32.50.

Answer:
Temperature on monday = 24 .35°c.
Step-by-step explanation:
Given : The temperature in Bloomington on Sunday was 32.6°C. On Monday, the temperature changed by -8.25°C.
To find : What was the temperature on Monday.
Solution : We have given
Temperature on sunday = 32.6°C.
Temperature changed = -8.25°C.
Temperature on monday = 32.6°C - 8.25°c )
Temperature on monday = 24 .35°c.
Therefore, Temperature on monday = 24 .35°c.

Step-by-step explanation:
The solution is Option B.
The volume of the triangular prism is given by the equation V = 432 feet³
What is the volume of a prism?A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.
The volume of a prism is the product of its base area and height
Volume of Prism = B x h
where B = base area of prism
h = height of prism
Given data ,
Let the volume of the prism be represented as V
Now , the equation will be
Let the base area of the prism be B
Let the height of the prism be h = 2 feet
Now , the length of the prism L = 18 feet
The width of the prism W = 12 feet
So , the base area B = L x W
Substituting the values in the equation , we get
The base area of the prism B = 216 feet²
So , Volume of Prism = B x h
Substituting the values in the equation , we get
Volume of Prism V = 216 x 2 feet³
Volume of Prism V = 432 feet³
Hence , the volume of prism is 432 feet³
