By rotating the picture counterclockwise, it is clear that it is a square.
Calculate the length of one side of the picture by using coordinates (1, -3) and (2,1).
a = [(2-1)^2 + (1+3)^2]^0.5 = (1 + 8)^0.5 = 3
The area of the picture is 3^2 = 9.
Calculate the area of the red paper.
Area = 8*8 = 64
Calculate the area of the red paper after the photograph has been cut.
Area = 64 - 9 = 55
Answer: 55
The equation of the function f(x) is f(x) = -x^3
<h3>How to determine the equation of f(x)?</h3>
The function is given as:
g(x) = x^3
When flipped over the x-axis, the rule is:
f(x) = -g(x)
So, we have:
f(x) = -x^3
Hence, the equation of the function f(x) is f(x) = -x^3

Answer:
26.230 Inches per second.
Step-by-step explanation:
Since, Area of square is decreasing at the rate of 43 square inches per second And area is directly proportional to square of the side , So
Its side will be decreasing at the rate of 
inches per second .
Now,
Perimeter of square is directly proportional to 4 times of the side of the square.
so Perimeter of square will be decreasing at the rate of 4×
After rounding off to three decimal places we will get 26.230 Inches per second.
