Mya should put 3/5 in each serving.
Answer: Please make me as brain list
Step-by-step explanation:
1. X= 0
2. X=-3/5
Rearrange the equation as
cos(x) - √(1 - 3 cos²x) = 0
cos(x) = √(1 - 3 cos²x)
Note that both sides have to be positive, since the square root function is non-negative. If we end up with any solutions that make cos(x) < 0, we must throw them out.
Take the square of both sides.
(cos(x))² = (√(1 - 3 cos²(x))²
cos²(x) = 1 - 3 cos²(x)
4 cos²(x) = 1
cos²(x) = 1/4
cos(x) = ± √(1/4)
cos(x) = ± 1/2
We throw out the negative case and we're left with
cos(x) = 1/2
This has general solution
x = arccos(1/2) + 360° n or x = -arccos(1/2) + 360° n
(where n is any integer)
x = 60° + 360° n or x = -60° + 360° n
Now just pick out the solutions that fall in the interval 0° ≤ x < 360°.
• From the first solution set, we have x = 60° when n = 0.
• From the second set, we have x = 300° when n = 1.
So the answer is D.
Answer:y = -2x
Step-by-step explanation:
slope-intercept form is as follows
y = mx + b
You are given that the slope is -2 and since the line passes through the origin, there is no y-intercept
So you just plug in the slope
y = -2x + b
And since there is no y-intercept, you can take that out.
y = -2x
Answer:
Step 1: If the radicals have the same index, multiply terms the outside the radical with terms outside the radical and terms inside the radical with terms inside the radical.
Step 2: Simplify the radicals.
Step 3: Multiply the terms outside the radical
