Suppose you deposit $6000 in a savings account that pays interest at an annual rate of 4% compounded continuously. How many years will it take for the balance in your savings account to reach $8000? Round your answer up to the nearest number of years.

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
