a relationship or expression involving one or more variables
An equation of the circle that will pass through the four (4) vertices of the square is (x + 2)² + y² = 2².
<h3>How to find the equation of this circle?</h3>
Mathematically, the general form of the equation of a circle is given by;
(x - h)² + (y - k)² = r²
Where:
- h and k represents the coordinates at the center.
- r is the radius of a circle.
<u>Note:</u> The center of a circle lies on the midpoint of the diagonal of a square, which is formed by joining its endpoints (opposite).
Midpoint on x-coordinate is given by:
Midpoint = (-2 - 2)/2
Midpoint = -4/2 = -2.
Midpoint on y-coordinate is given by:
Midpoint = (-2 + 2)/2
Midpoint = 0/2 = 0.
Thus, the center (h, k) = (-2, 0).
For the radius, we have:
r = √(-2)² + 0²
r = √4 = 2.
Substituting the parameters into the general equation, we have;
(x - (-2))² + (y - 0)² = 2²
(x + 2)² + y² = 2²

Answer:
the answer is 1.453
Step-by-step explanation:
i am not sure about the answer but here are my steps. first he says in the 1990s there was a deforestation rate of about 0.48%per year. and 1 is the rate of land that is shrinking. this means that if Brazil had a forest of area x then
x(0.48%)=1 therefore x=2.083
lets use that in this equation
the area left (the final answer) 2.083(0.48)^35= 1.453
(i asked about the unit its measured with because if it is measured by thousands of squared meters or kilometers just big unit measured to be exact my answer would be correct)
