Answer:
The center is at (0,0)
The vertices are at ( (
±2 sqrt(2),0)
foci are (
±sqrt(5),0)
Step-by-step explanation:
3x^2 + 8y^2 = 24
Divide each side by 24
3x^2 /24 + 8y^2/24 = 24/24
x^2/8 + y^2 /3 = 1
The general equation of an ellipse is
(x-h)^2/ a^2 + (y-k)^2 / b^2 = 1
a>b (h,k) is the center
the coordinates of the vertices are (
±a,0)
the coordinates of the foci are (
±c,0), where ^c2=a^2−b^
2
The center is at (0,0)
a = sqrt(8) = 2sqrt(2)
The vertices are at ( (
±2 sqrt(2),0)
c = 8 - 3 =5
foci are (
±sqrt(5),0)
Since cube has all faces as Squares
perimeter of each face P = 22.2
as we know perimeter of a square is P = 4 * ( Sides of a square )
let the sides of the square be 'x'
Hence , 22.2 = 4 * x
=> x = 22.2/4
=> x = 5.55
hence the edge's length is 5.55
Note : if the length from edge to edge is asked then
Length of the Diagonal for a cube =

Hence we get edge to edge length as
√3 * 5.55 = 9.612

Answer:
y = -5
Step-by-step explanation:
The coordinate point is in the format (x, y)
Therefore, the y-value of (4, -5) is -5
So the equation of the horizontal line is therefore y = -5
