Identify a1 and r for the geometric sequence an= -256(-1/4) n-1

Find dy/dx using implicit differentiation ln(20+e^xy)=y

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
