1. You have that the Standard form for the equation of a circle when its center is at the origin, is:
x²+y²=r²
2. You must calculate the radius. Then:
r=√(x²+y²)
x=24
y=32
3. When you substitute the values of "x" and "y" into the equation r=√(x²+y²), you obtain:
r=√(x²+y²)
r=√(24²+32²)
r=√(576+1024)
r=√1600
r=40 feet
4. Therefore, the diameter (D) of the circle, is:
D=2r
D=2(40 feet)
D=80 feet
Answer:
y equals 3/2 - 1/2 x.......
Line A is the correct answer because the line crosses the 7 dish point at the one minute point
Answer:
d Dilation by a scale factor of 2 followed by reflection about the y-axis
Step-by-step explanation:
In each case, the transformation is ...
(x, y) ⇒ (-2x, 2y)
So, a dilation by a factor of 2 is involved. That is what multiplies the coordinates by 2. Reflection in the y-axis is what negates the x-coordinate.
The transformations are ...
