A dynamic blast blows a heavy rock straight up with an initial velocity of 49m/s. the function
h(t) represent the height of the rock after t seconds.
A. How high does the rock go ?
B. When does the rock hit the ground again ?( Use factoring )
C. Will the rock reach a height of 120 m ? (explain using the discriminant)
D. When does the rock reach a height of 100 m ? (use the quadratic formula ) ( approximate
your answers to two decimal places )
E. Sketch the graph of the parabola include intercepts , vertex and and and at h=100m.

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.
