Answer:
Option B.
Step-by-step explanation:
From the given table it is clear that the linear function passing through the points (-14,-18) and (-10,-12).
The slope of a linear function is
The given line passing through the points (-14,-18) and (-10,-12), so the slope of the line is
The slope of the required line is .
Therefore, the correct option is B.
Answer:
Step-by-step explanation:
We want to find sin(θ) and cos(θ) given that tan(θ) = 1/4 and sin(θ) > 0.
First, since tan(θ) and sin(θ) are both positive, cos(θ) must be positive as well.
Recall that tangent is the ratio of the opposite side to the adjacent side.
Therefore, the hypotenuse is:
So, with respect to θ, the opposite side is 1, the adjacent is 4, and the hypotenuse is √17.
Then it follows that:
And that:
