the roof of a building is in the shape of the hyperbola y^2-x^2=40 , where x and y are in meters.determine the distans , w , between the walls.

i missed one information A=10 meters but i can not sketch it!! what to do?

To determine the distance, w, between the walls of the roof, we need to find the horizontal distance (x) between the points where the hyperbola intersects the y-axis.

The equation of the hyperbola is given as y^2 - x^2 = 40.

To find the x-values where the hyperbola intersects the y-axis, substitute x = 0 into the equation:

0^2 - x^2 = 40
-x^2 = 40
x^2 = -40

Since we cannot take the square root of a negative number with real numbers, we conclude that the hyperbola does not intersect the y-axis in the real number system. This means that the distance between the walls, w, is undefined for this particular hyperbola equation.

However, if the equation was y^2 - x^2 = -40, we would have imaginary solutions for x, indicating that the hyperbola does not exist in the real number system.
