A person standing close to the edge on top of a 165-foot building throws a baseball vertically upward. The function s(t) = - 16t ^ 2 + 101t + 165mods the ball's height , in feet above the ground, seconds after the ball is thrown After how many seconds does the ball reach its maximum height? Round to the nearest hundredth of a second. Need help ASAP

Which equation represents a circle with a center at (–3, –5) and a radius of 6 units? (x – 3)2 + (y – 5)2 = 6 (x – 3)2 + (y – 5)2 = 36 (x + 3)2 + (y + 5)2 = 6 (x + 3)2 + (y + 5)2 = 36

The quadratic function h(t)=-16.1t^2+150 choose the graph representation

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
