The equation when rewritten is 
<h3>Calculations and Parameters:</h3>
When we consider the vertex form of the equation:
y= 3(x-2)^2 - (x-5)^2
Expanding further:
2((x-0.5)^2 - 27/4) = 2( (x-0.5)^2)- 27/2
Thus, the final form of the equation would be

The sin ratio is the side opposite the reference angle over the hypotenuse. If Z is our reference angle, then the side opposite it has a length of 32. The hypotenuse has a length of 40. Therefore, the sin of Z = 32/40. We will reduce that to sin Z = 4/5. First choice above.
Tan (x) = 0.8. To calculate the angle x, find the tan⁻¹ (0.8) = 38.7°

Answer:
C
Step-by-step explanation:
(x,y) = p + t(a)
(x,y) = (-1,6) + t(3,-1)
(x,y) - (-1,6) = t(3,-1)
(x + 1, y - 6) = t(3, -1)
