Suppose we apply the translation map Tv to each point on the circle (x + 4)^2 + (y − 3)^2 = 25.
1 answer:
Answer:
(-4,3) , r = 5
Step-by-step explanation:
given,
equation of circle
(x + 4)² + (y − 3)²= 25.
general equation of the circle
(x - a)² + (y - b)² = r²
comparing the given equation from the general we get,
radius = r² = 25
r = 5
-a = 4 -b = -3
a = -4 b = 3
the center of the circle is (-4,3)
hence, all the specification is shown in the image attached below

Let x represent the length of the side of the pen that is parallel to the barn. Then the area (y) will be
.. y = x(300 -x)/2
This describes a downward opening parabola with zeros at x=0 and x=300. The vertex (maximum) will be found at the value of x that is halfway between those, x = 150.
For that value of x, the pen area is
.. y = 150(300 -150)/2 = 150^2/2 = 11,250 . . . . . square feet.
