Answer:
-7/18
Step-by-step explanation:
cos(2x) = 1 - 2sin²x
cos(2x) = 1 - 2(5/6)²
= 1 - 2(25/36)
= 1 - 25/18
= -7/18
Answer Using the method of alligation. 40.0= 20/(10/20) qts of 50% solution to add to your 20 qts of 20% solution. 60.0= (20+40.0) qts of the final 40% solution.
Answer:

Step-by-step explanation:
The line that passes through the two points (6, -23) and (11, r) has a slope of 4.
We want to determine the missing value of r.
We can use the slope formula:

Let (6, -23) be (x₁, y₁) and let (11, r) be (x₂, y₂). The final answer should be 4. Therefore:

Simplify and evaluate:

Multiply both sides by 5:

Therefore:
