Answer:
D)
Step-by-step explanation:
The first step is to find the vertex.
Start with getting your coefficients:
a = 1, b = -6, c = 6
plug them into the equation
Plug that back into the original equation to get y = -3
The vertex is going to be (3, -3)
The equation for Vertex Form is given by
(a) being the coefficient in front of the
(h) being the first point on the vertex (h,k) ({3},-3)
(k) being the second point on the vertex (h,k) (3,{-3})
Answer:
C
Step-by-step explanation:
Remember the mnemonic: SohCahToa, where:
Let's determine our side lengths first.
Note that our angle is A. So, we have to determine the sides with respect to A.
The opposite side to A is 16.
The adjacent side is 12.
And the hypotenuse is 20.
With this, we can find our trig ratios:
Sine:
Substitute 16 for the opposite and 20 for the hypotenuse. This yields:
Reduce:
Cosine:
Substitute 12 for the adjacent and 20 for the hypotenuse. This yields:
Reduce:
Tangent:
Substitute 16 for the opposite and 12 for the adjacent. This yields:
Reduce:
So, our answers are:
Out of the answer choices, the choice that represents this is C.
So, our correct answer is C.
And we're done!
