Answer:
The length for on side is 10.5.
Step-by-step explanation:
6.5 + 6.5 = 13
34 - 13 = 21
21 divided by 2 is 10.5
Length 10.5 + 10.5 + 6.5 + 6.5 = 34
Answer:
The answer to your question is Area = 49n² - 70n + 25
Step-by-step explanation:
Data
Length of the side = 7n - 5
Formula
Area of a square = side x side
Process
1.- Substitute values
Area = (7n - 5)(7n - 5)
2.- Expand
Area = 49n² - 35n - 35n + 25
3.- Simplify
Area = 49n² - 70n + 25
4.- The polynomial is 49n² - 70n + 25
20 and 7 Because 4x5 = 20
The answer to that question would be 14
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.
