Question

Alg 1 Honors, Help please! (Medals)

1) A firecracker shoots up from a hill 145 feet high with an initial speed of 80 feet per second. Using the formula H(t) = −16t2 + vt + s, approximately how long will it take the firecracker to hit the ground?

13 seconds

11 seconds

9 seconds

6 seconds

2) Using graphing technology, approximate the solutions of 0.35x2 − 2.52x + 1.34 = 0.

x ≈ 0.12 and x ≈ 4.56

x ≈ 0.58 and x ≈ 6.62

x ≈ 1.17 and x ≈ 6.14

x ≈ 1.83 and x ≈ 4.84

Answer 1

First we have to figure out what v ans s are in the equation H(t) = −16t2 + vt + s.
What is v in this equation?
