X^2+y^2 = 16
can be written as
(x-0)^2+(y-0)^2 = 4^2
We see that the second equation is in the form
(x-h)^2 + (y-k)^2 = r^2
where
(h,k) = (0,0) is the center
r = 4 is the radius
The polar form of the equation is simply r = 4. Why is this? Because the radius is fixed to be 4 no matter what happens with theta. As theta goes from 0 to 360, the points generated all form a circle centered at (0,0) with radius 4.
Answer: r = 4
Slope intercept: y=mx+b
1. plug in values
point: (3,10); slope: 4—> 10=4(3)+b
2. solve for b
3. write the equation as y=4x+b (you will have found “b”)
Hope this helps!

Answer:
B) Dilations increase angle measures.
Step-by-step explanation:
Dilations have no effect on angle measures, but they uniformly change the size and spacing of line segments. They are a non-rigid transformation that leaves geometric figures similar to the original.
The false statement is B.
Answer:
The turtle will go 18 miles in 90 minutes.
Step-by-step explanation:
6 divided by 30 = 0.2
0.2 x 90 = 18
18 miles
