I do not think your sum of matrix A and matrix B is correct I get the first matrix: 1 2 3 1 0 1 1 2 1 the second matrix: 1 1 1 2 2 2 3 3 3 The total of two matrices: 2 3 4 3 2 3 4 5 4 in flow chart form: do 1 from n = 1 to 3 do 1 from m = 1 to 3 1 output (n,m) = inputA(n,m) + ...
Math 112 Help please
a is bigger than b and bigger than 13,579 because of the + sign c and d are smaller than 13,579 because 13,579 is divided by something bigger than 1

dg/dx = [ ln x (1) - x (1/x) ] / (ln x)^2 = [ln x - 1 ] / (ln x)^2 that is zero when x = e or x = about 2.72 is that a max or a min? you could take another derivative, but easier to check when x = 2.5 or something if x = 2.5 dg/dx = [.916 -1 ] / .84 = negative so as x goes fro...

ke at bottom = (1/2) m v^2 = m g h so v at bottom = sqrt (2 g h) so average v = max v/2 = (1/2) sqrt(2 gh) average v = .5 sqrt(2*9.81*200) = 31.3 m/s time = distance /speed = 200 /average v = 200/31.3 = 6.39 seconds
