I have no clue how to do this, and I don’t even know how to explain how to do it.. so hopefully one of y’all can help me out, that’d be great:)

Acircle has a radius of 5/6 units and is centered at (3.6, 7.8) write the equation of this circle

The lengths of two sides of a right triangle are given. find the length of the third side. round to the nearest tenth if necessary. a) y = 12/5x + 39/5 b) y = 5/12x + 5/39 c) y = 12/5x - 39/5 d) y = 5/12x - 5/39

Simplify (1/2)4th power a. (1/16) b.(1/8) c.(1/4)
