Find the degree measure of the angle between the vectors. (Round your answer to two decimal places.) u = −10i − 5j
v = −6i + 3j

= °

What is the multiplicative rate of change of the exponential function shown on the graph?

What is the solution to the system of equation graphed belowa.(0,-4)b.(2,5),1),-3)

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.
