15. Use the unit circle to find the value of sin 3x/2 and cos 3x/2
Answers
Answer:
3xpi/2 is 270 degree counter-clockwise from Ox
That time P(x,y) is (0,-1)
=> x= 0 and y = -1 as you can see in picture.
=> Cos 3pi/2 = x = 0
=> Sin 3pi/2 = y = -1

All of them except 8/100 because it results 0.08 or 8%.
The rest:
2/5 = 0.4 = 40%
8/20 = 0.4 = 40%
4/10 = 0.4 = 40%
16/40 = 0.4 = 40%
8/100 doesn’t equal to 40 because it’s already over 100
2/5 x 20 = 40/100
8/20 x 5 = 40/100
4/10 x 10 = 40/100
16/40 divide by 2 = 1/5 x 20 = 20/100
So your answers are 2/5, 8/20 and 4/10

To find how much the temperature fell we must find the difference of both numbers and to do this we subtract them;
20 - (-5) = 25 degrees

We first have to change the mixed number into a fraction and we do this by multiplying the denominator to the whole number and adding the product to the numerator.
It looks something like this:
4×1=4 (Multiply the denominator and the whole number)
4+3=7 (Add the product and the numerator)
Keep the same denominator
Now that we have the improper fraction, we can subtract.
Now in order to subtract we have to have a common denominator, so lets make both of the denominators 20.
21÷20=1.05 or

1x3=3+4=7
7/4-7/10
now make a common denominator
the common denominator is 20 so do 4x5=20 and 10x2=20
do the same to the numerators 7x5=35 and 7x2=14
35/20-14/20
the answer as an improper fraction is 21/20 and as a mixed number it is 1 1/20

Final answer:
The mean of 87, 93, 86, 90, and 84 is 88.
Explanation:
To find the mean of a set of numbers, you need to sum up all the numbers in the set and then divide by the total number of values. For this set, the sum is 87 + 93 + 86 + 90 + 84 = 440. There are 5 numbers in the set, so to find the mean, you divide the sum by 5: 440 ÷ 5 = 88.
