A circle is centered at (5, −9) and has a radius of 12. Which of the following is the equation for this circle? (x − 5)2 + (y + 9)2 = 12 (x − 5)2 + (y + 9)2 = 144 (x + 5)2 + (y − 9)2 = 144 (x + 5)2 + (y − 9)2 = 12

Aprism and two nets are shown below: image of a right triangular prism and 2 nets. the triangle bases have base 4, height 3, and diagonal side 5. the length of the prism from the bases is 9.4. net a has 3 rectangles in a row. the middle one has sides ac and cd. this middle one has triangle abc on top and identical triangle below. net b is the same except that the triangle base abc is on top of the last rectangle which has sides ac and cd. units are in inches. part a: which is the correct net for the prism? explain your answer. (2 points) part b: write the measurements of sides ab, bc, and cd of the correct net. (4 points) part c: what is the surface area of the prism? show your work. (4 points)
