-the equation is a quadratic
-the axis of symmetry is x=-7
-the graph has a relative maximum
Answer:
-4,-1
i have to put 20 character so here is 20 characters
12 red counters
7 more red counters than yellow counters
12 - 7 = 5 yellow counters
Dara has 5 yellow counters.
Use the kinematics equation:
v1^2-v0^2=2as
since v1=0 (at height of 81 ft), and a=g=-32.2, substitute values:
0-v0^2=2*(-32.2)(81 ft)
Solve for v0
v0=sqrt(2*32.2*81)=72.2 m/s
