On a piece of paper, use a protractor to construct right triangle abc with ab = 4 in. m ∠a = 90 °, and m ∠b=45 ° what statement is true about the triangle? a) bc = 8 in. b) bc = 4 in. c) ac = 4 in. d) ac = 2 in.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
