The exponential decay function A = A0(1/2)^t/P can be used to determine the amount A, of a radioactive substance present at time t, if A0 represents the initial amount and P represents the half-life of the substance. If a substance loses 70% of its radioactivity in 500 days, determine the period of the half-life.

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.
