The equation x2 − xy + y2 = 3 represents a "rotated ellipse," that is, an ellipse whose axes are not parallel to the coordinate

axes. Find the points at which this ellipse crosses the x-axis.(x, y) = smaller x-value (x, y) = I larger x-value

Answer:

the points where the ellipse crosses the x- axis are (1.73, 0) and (-1.73, 0)

Step-by-step explanation:

To find the points at which a graphic crosses the x-axis we need to find the values for x where y = 0.

Therefore, in the equation x²- xy + y² = 3 we are going to make y = 0 and solve for x

x² - xy + y² = 3

x²- x(0) + (0)² = 3

x² = 3

x = ±√3

x₁ = 1.73 and x₂ = -1.73

Therefore, the points where the ellipse crosses the x- axis are (1.73, 0) and (-1.73, 0)

A rectangle measures 16 cm by 4 cm. It has the same area as a square. Find the perimeter of the square.
Elis [28]

ok ... in this situation... we need to find the area of the rectangle first as it is equal to the area of square .

so .... area of rectangle = l×b= 16×4

= 64 ∴area of square = 64

area of square = s×s

∴to find one side of the square ... we need to find the root of 64 = 8

∴one side = 8

now : perimeter of square : 4 × sides = 4 × 8 = 32 ║
