Solve the problem. A projectile is thrown upward so that its distance above the ground after t seconds is h= 40:2 + 44m. After how many seconds does it reach its maximum height? Find the exact value of the expression. Do not use a calculator. cot 45 - sin 45 _ 0 b 243345 0 Find the vertex and axis of symmetry of the graph of the function. f(x) = x2 - 10x 0 (-5, 25); x = -5 O (-25, 5); x = -25 O (5, -25); x = 5 Q (25, -5); x = 25 Perform the indicated operations and simplify the result. Leave the answer in factored form. x2+ 12x +36 x2+2x x2 - 4 x +6 x(x + 6) O x - 2 x(X + 6) O x +2 X O x +2 (x + 6) O x - 2An expression that occurs in calculus is given. Factor completely. (2x + 1)2 + 3(2x + 1) - 4 2x(2x + 5) 2x - 1 O 2x(2x + 1) O 2x - 6
