Using trigonometry table :
Sine 0 = 0
Cosine 0 = 1
Tangent 0 = 0
Co-secant 0 = 1/sine 0
= 1/0
= undefined
Secant 0 = 1/cos 0
= 1/1
= 1
Cotangent 0 = 1/tan 0
= 1/0
= undefined<span />
Step-by-step explanation:
the slope is the ratio of "y coordinate difference / x coordinate difference".
so, let's find 2 good points (I mean by that with integer coordinates). I see e.g.
(-1, -1) and (0, -7)
x changes by +1 (from -1 to 0).
y changes by -6 (from -1 to -7).
so, the slope is -6/1 = -6.
D is the right answer.
The x-coord. of the vertex is halfway between the given zeros. Here, it'd be halfway between x=3 and x=9, which comes out to x = 6 (answer).
Triangle PQR and triangle A, B, C, and D are represented on the following graph.
Translating a shape gives the effect of 'moving' the shape only. The transformation does not cause a shape to change direction or to change size.
The triangle that represents the translation of PQR is triangle D. The translation is 0 unit on the x-axis and 2 units down
16x-7.1 is the doubled version of that expression
