Here we go ~
The general equation of ellipse is :
[ because it's a horizontal ellipse with centre at origin ]
so, let's equate given equation with the standard equation ~
se get :
As we know, length of minor axis is : 2b = 2 × 6 = 12 units
and, the smaller circle has diameter = 2b = 12 units
so, it's radius = 6 units ~
Now, let's write the equation of circle with origin as centre and radius = 6 units
[ h = 0, k = 0, since circle has centre at origin ]
Y=2x-3 Y=2x-3
X+Y=18 X+Y(2x-3)=18
X+2x=18+3
3x=21
x=21/3 (or 21:3)
x=7
Answer:
The answer is 144 m 2, hope this helps!!!:)
Answer:
6; 22; 20 (ft.)
Step-by-step explanation:
1) if the length of the each side are: n; 4n-2 and 4n-4, then the expression of the perimeter can be written: P=n+4n-2+4n-4 or P=9n-6.
2) if according to the condition perimeter is 48 (ft.), then
9n-6=P; ⇔ 9n-6=48; n=6.
3) if n=6, then the required lengths of the sides are:
n=6 (ft.);
4n-2=22 (ft.);
4n-4=20 (ft.)
