If u mean 4^4 or four to the fourth power then it’s 256
Step-by-step explanation:
The equation of a parabola with focus at (h, k) and the directrix y = p is given by the following formula:
(y - k)^2 = 4 * f * (x - h)
In this case, the focus is at the origin (0, 0) and the directrix is the line y = -1.3, so the equation representing the cross section of the reflector is:
y^2 = 4 * f * x
= 4 * (-1.3) * x
= -5.2x
The depth of the reflector is the distance from the vertex to the directrix. In this case, the vertex is at the origin, so the depth is simply the distance from the origin to the line y = -1.3. Since the directrix is a horizontal line, this distance is simply the absolute value of the y-coordinate of the line, which is 1.3 inches. Therefore, the depth of the reflector is approximately 1.3 inches.

Step-by-step explanation:
The slope-intercept form of an equation of a line is given by:
y = mx + b, where m = slope and b = y-intercept
Given the slope and point on a line, you can solve for 'b' in the equation:
(3, 3) - x = 3, y = 3
slope =
Plug into the equation:
3 = *3 + b
3 = 7 + b
-4 = b
y = x - 4
