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.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
