Using coordination notation describe a transformation that shows that trapezoid HIJK is similar to trapezoid H’I’J’K

which  best  describes the transformation from the graph of  f(x) =  x2  to the graph of  f(x) = (x  – 3)2  – 1?   left 3 units, down 1 unitleft 3 units, up 1 unitright 3 units, down 1 unit  right 3 units, up 1 unit

1. how do you convert the repeating, nonterminating decimal 0. to a fraction? explain the process as you solve the problem.

If tan2a=cot(a+60), find the value of a, where 2a is an acute angle
