An object is thrown upward at a speed of 121 feet per second by a machine from a height of 8 feet off the ground. the height h of the object after t seconds can be found using the equation h = -16t^2+121 t+8
when will the height be 17 feet?
when will the object reach the ground?

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
