The team mascot shoots a rolled T-shirt from a special T-shirt cannon to a section of people in the stands at a basketball game.
The T-shirt starts at a height of 8 feet when it leaves the cannon and 1 second later reaches a maximum height of 24 feet before coming back down to a lucky winner.
If the path of the T-shirt is represented by a parabola, which function could be used to represent the height of the T-shirt as a function of time, t, in seconds?
f(t) = –16(t – 1)2 + 24
f(t) = –16(t + 1)2 + 24
f(t) = –16(t – 1)2 – 24
f(t) = –16(t + 1)2 – 24

<h2>The reliability is 0.999999.</h2>Step-by-step explanation:
The failure rate for a guided missile control system is 1 in 1,000.
Hence, the probability that the missile will not fail is .
According to the new system, if the first fails, the second can take over.
There are two possibilities, either the first one will be fail or not.
If the first one will not fail, then the probability will be = 0.999.
If the first one will fail, then the probability will be .
The reliability of the modified missile is 0.999 + 0.000999 = 0.999999.
