What is the diameter of the circle (x + (9/2))^2 + y^2 = 16? Write your answer in simplified, rationalized form.
Added by Andrew P.
Step 1
The given equation is in the form (x + (9/2))^2 + y^2 = 16. To rewrite it in standard form, we need to expand the square term. (x + (9/2))^2 + y^2 = 16 (x + (9/2))(x + (9/2)) + y^2 = 16 (x^2 + 2(x)(9/2) + (9/2)^2) + y^2 = 16 (x^2 + 9x + (81/4)) + y^2 = 16 x^2 + Show more…
