<span>A. tan Y= y/z
Just remember the three major identities for trig with a right triangle.
sin Î¸ = opposite/hypotenuse
cos Î¸ = adjacent/hypotenuse
tan Î¸ = opposite/adjacent
And in the diagram, the opposite side to Y is y and the adjacent side is z. So the tangent is y/z which matches option "A" from your choices.</span>

By definition you have that the tangent of an angle in a right triangle is given by the quotient between the sine of the angle and the cosine of the angle.
Since we know how much the sine and the cosine measure (we have the sides of the triangles as data), then the tangent is given by:
A. tan Y= y/z
answer
A. tan Y= y/z

Sketch the quadratic function ƒ(x) with a vertex at (–1, 2) and the points (0, 0) and (–2, 0). Which statement describes the par

KATRIN_1 [288]

Answer:

I believe it is C) decreasing when x > -1

Step-by-step explanation:

If you plot all 3 points on a graph, you will notice that the parabola is facing downwards. This means that on the left side of the vertex, it is increasing (the y-value increases). On the right side of the vertex, it decreases (y-value decreases). Note that "decreasing" refers to the y values.

So, since the vertex's x-value is -1 (we know this from the point (-1, 2)), any x-value greater than -1 will be to the right of the vertex. For example, 0, 1, 2, 3, etc. are all greater x-values than -1, so they are all to the right of -1. Since they are on the right, that means the corresponding-values will be decreasing.

Therefore, when x > -1, the parabola is decreasing.
