Circles follow ghe equations
(x-h)^2 + (y-k)^2 =r^2
with center (h,k) and radius r
for this circle it would be
(x-7)^2 + (y-4)^2 = 100

If the diameter is 10, then the radius is 5. (x-7)² + (y-4)² = 5²
The answer is (x-7)² + (y-4)² = 25

Focus Question: How do you determine whether a real-world context should be

Yakvenalex [24]

Answer:

Simplify the equation as closely as possible to the form of y = mx + b. Check to see if your equation has exponents. If it has exponents, it is nonlinear (exponential). If your equation has no exponents, it is linear.

List 2/3 , 7/12 , and 3/4 from greatest to least thanks .

nikklg [1K]

For this question you should know that:
2/3 = 8/12
and
3/4 = 9/12
so now you can say:
7/12 < 8/12 < 9/12
so:
7/12 < 2/3 < 3/4 :)))
i hope this is helpful
have a nice day

Can someone give me some tips of how to study. I have already tried writing everything in my lesson but it doesn't seem to work

Ainat [17]

Study all notes, reread the chapters again. Have someone ask questions on the chapters page by page. This always has worked for me. Plus try to do this again the night before the test. You will be surprised how much you can remember by doing it again the night before the test. Hope this helps.

*Find the area of the figure below. Use 3.14 for pi.<br><br> Area= square inches

alex41 [277]

Answer:

100.26

Step-by-step explanation:

You would find the area of the semi circles on either side of the rectangle by plugging the diameter into the formula for the area of a circle. Then you would add that to the are of the rectangle.

This is what that would look like:

1. Divide 6 (the diameter) by 2 because $r=\frac{1}{2} d$
