The correct answer is:
True.
Explanation:
A sinusoidal function is based on the sine function, or sine wave.
The sine wave repeats based on its period. The period of the sine function is 2π, or 360°. Depending on the transformations applied to the function, the period of the transformed function may be different, but will always be based around this idea of repeating every 2π radians.
Since 2π = 360°, this corresponds with a circle. This means the graph repeats based on positions of a point that move around a circle.

True

Answer: (y - 9)^2 = -48(x - 7)
Step-by-step explanation:
To find the equation of the parabola in standard form, we can use the formula (y - k)^2 = 4p(x - h), where (h, k) is the vertex and p is the distance between the vertex and the focus.
Given that the vertex is (7, 9) and the focus is (-5, 9), we can see that the vertex and focus have the same y-coordinate, which means the parabola opens horizontally.
The vertex is (h, k) = (7, 9) and the focus is (h + p, k) = (-5, 9). By comparing the x-coordinates, we can find p.
-5 = 7 + p
p = -12
Substituting the values into the formula, we get:
(y - 9)^2 = 4(-12)(x - 7)
So, the equation of the parabola in standard form is (y - 9)^2 = -48(x - 7).
