A child drops a rock off a building that is 64 feet tall. If the equation for height
as a function of time is
h(t) = -16t2 + initial height wheret is
time in seconds and h(t) is height in
feet, how many seconds will it take for
the rock to hit the ground?

Write the fraction or mixed number and the decimal shown by the model

The triangles in the diagram are congruent. if mzf = 40°, mza = 80°, and mzg = 60°, what is mzb?

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
