Answer:
(x +6)^2 +(y -10)^2 = 225
Step-by-step explanation:
The standard form equation for a circle is ...
(x -h)^2 + (y -k)^2 = r^2
where the center is (h, k) and the radius is r.
The center of a circle is the midpoint of any diameter. The midpoint between two points is the average of their coordinates.
((-15, -2) +(3, 22))/2 = (-15+3, -2+22)/2 = (-6, 10)
The radius can be found using the distance formula, or by simply putting one of the given points in the equation for the circle to see what the constant (r^2) needs to be.
(x -(-6))^2 +(y -10)^2 = (-15-(-6))^2 +(-2-10)^2
(x +6)^2 +(y -10)^2 = 81 +144 = 225
The equation of the circle is ...
(x +6)^2 +(y -10)^2 = 225
Answer:
1) Place the compass point at the vertex of the angle and open it to any width. Draw an arc that intersects of the sides of the angle.
2) Place the compass point at the one of the intersection points. Place the pencil at the other intersection point. This sets the compass with.
3) Draw an arc inside the angle.
4) Move the compass point to the intersection point on the other side of the angle being sure to keep the compass width the same. Draw a second arc inside the angle.
5) Make a point where the 2 arcs intersect the angle. Use a straight edge to draw a ray from the vertex of the angle through the point.
Answer:
Hence the dimensions are 5×5 i.e. 5 meters and 5 meters such that its field would be as large as possible.
Step-by-step explanation:
Darek's dad has a 20 m fencing mesh.
Since we have to make a rectangular garden with he help of fencing the garden using this mesh, that means perimeter of this garden is 20 m.
i.e. 2( l+b)=20
also we have to fenced in such a way that its field would be as large as possible.
ie. it has the largest Area.
Now we will start from the dimensions possible as:
9×1 whose area will 9 m^2 (since Area=l×b)
Next dimension will be:
8×2 whose area will be 16 m^2
Next will be:
7×3 whose area will be 21 m^2
Next will be:
6×4 whose area will be 24 m^2
Next will be:
5×5 whose area will be 25 m^2
Next will be:
4×6 whose area will be same as of 6×4.
Hence, we get the maximum area to be 25 m^2 which is obtained when the dimensions are 5×5.
