Answer: cos(Θ) = (√15) / 4
Explanation:
The question states:
1) sin(Θ) = 1/4
2) 0 < Θ < π / 2
3) find cos(Θ)
This is how you solve it.
1) Use the fundamental identity (in this part I use α instead of Θ, just for facility of wirting the symbols, but they mean the same for the case).

2) From which you can find:

3) Replace sin(α) with 1/4
=>

=>

4) Given that the angle is in the first quadrant, you know that cosine is positive and the final answer is:
cos(Θ) =

.
And that is the answer.

<span>Rectangles have a couple of properties that help distinguish them from other parallelograms. By studying these properties, we will be able to differentiate between various types of parallelograms and classify them more specifically. Keep in mind that all of the figures in this section share properties of parallelograms. That is, they all have</span>
Answer:
A: Independent
Step-by-step explanation:
Y = 3x - 1
The format for slope intercept form is:
y = mx + b
m represents the slope and that was given so:
y = 3x + b
Now we have to substitute the value from the given point into “y” and “x” to solve for “b”
(2) = 3(1) + b
2 = 3 + b
-1 = b
Now that we know b we can substitute it into y = 3x + b to get the equation of the line
y = 3x - 1
