Mathematics
Thomas tosses a rock out of a hole 6 foot deep with an initial upward velocity of 24 feet per second. The height h in feet of the ball above the ground can be modeled by h = -16t^2 +24t - 6, where t is the time in seconds after Thomas hit the tennis ball. Find the times it takes for the rock to reach 2 feet above the ground.

Step-by-step explanation:
Let's do it by parts.
Let's consider a fact: there has to be only one winner. After six games:
So,![a_{6}=1](/tpl/images/0604/0790/a3449.png)
Since it's a decreasing Geometric Sequence (we have to lead to one winner), and each match two teams play, the beaten one leaves the championship.
a) Explicit Rule (Formula):
That's to say the tournament started with 32 teams
b) Recursive Rule
If we have the first term of the Geometric Sequence we can recursively find the subsequent terms. The Recursive Rule is useful when we have the prior term and we need the following one. Also, to derive the explicit rule.
