Find the exact value of Cosine (alpha + beta) given sin Alpha = two-fifths for Alpha in Quadrant II and Cosine Beta = one-third for Beta in Quadrant IV.
The exact value of cos (α + β) is (4√2-21) / 15.
What is angle?An angle is the formed when two straight lines meet at one point, it is denoted by θ.
Given that,
Sin α = 2/5, and α is in second quadrant,
cos β = 1/3 , and β is in fourth quadrant
Since, α is in second quadrant, the value of cos α will be negative.
The value of cos α, by right angle triangle property,
cos α = -√21 / 5
Since, β is in the fourth quadrant, the value of sin β will be negative.
The value of sin β = - 2√2 / 3
Cos (α + β) = cos α.cos β - sin α. sin β
Substitute the values here,
Cos (α + β) = (-√21 / 5) . 1/3 - 2/5. ( - 2√2 / 3)
= -21/15 + 4√2/15
= (4√2-21) / 15
The value of cos (α + β) is (4√2-21) / 15.

Step-by-step explanation:
-6=8x-14 show all steps please
Answer:
1=x
Step-by-step explanation
Add 14 to both side(because it is opposite)
-6=8x-14
+14 +14
8=8x
Divide both sides by 8
8/8=8x/8
1=1x(or just 1=x)
The answer will be X=1.

This table shows the input and output values for a linear function f(x). What is the difference of outputs for any two inputs that are one value apart? −30 −25 1 20
Answer:
-25.
Step-by-step explanation:
What is the difference of outputs for any two inputs that are one value apart?
If you look at the column of "x" [input], you will see that they are 1 unit apart. You can thus look at the corresponding values of "f(x)" [output] and determine their difference. Checking all of those, gives us the difference (same for all).
Output 2 - Output 1:
Output 3 - Output 2:
Output 4 - Output 3:
Output 5 - Output 4:
So the difference of outputs for any two inputs one value apart are

Alex was put on an improvement at work and they lowers his pay by 3% an hour before his decrease in pay he was making $14 an hour how much money is Alex making an hour afther his decrease in pay
Answer: Alex is making $ 13.58 after his decrease in pay.
Step-by-step explanation:
Given: Hourly pay for Alex before decrease in pay = $14
His salary decreased by 3%.
New hourly pay = Previous hourly pay - 3% of ( Previous hourly pay )
= $(14-0.03 (14))
= $ (14(1-0.03))
= $ (14(0.97))
=$ 13.58
Hence, Alex is making $ 13.58 after his decrease in pay.
