Find matrices of orthogonal projections onto all 4 fundamental subspaces of the matrix a = 0 @ 1 1 1 1 3 2 2 4 3 1 a : note, that really you need only to compute 2 of the projections. if you pick an appropriate 2, the other 2 are easy to obtain from them (recall, how the projections onto e and e? are related).

Question 2 of 5 samantha works in a bakery. the profit of cupcakes in dollars, after t weeks, is given by the function, c(t) = 0.1t3. the profit of cookies in dollars, after t weeks, is given by the function, k(t) = 5(1.07)t - 5. which function describes the total profit, m(t), at the bakery after t weeks? m(t) = 0.1t3 + 5(1.07)t - 5 m(t) = 0.1t3 + 5(1.07)t + 5 m(t) = 10t3 + 5(1.07)t - 5 m(t) = 0.1t3 - 5(1.07)t - 5
