Step-by-step explanation:
Answer:
where 
Step-by-step explanation:
This is an arithmetic sequence with the first term is 
= -2.7 and has a common difference of 
.
Arithmetic Sequence: 
is the nth term and 
is the common difference.
The common difference: -2.7, -8.3, -13.9...
Subtract: -2.7- (-8.3) = -5.6, -13.9 - (-8.3) = -5.6
Common difference: 
Recursive rule: 
For a sec, I thought this was AB Calculus with derivatives and second derivatives but it isn't! That's a good thing!
Anyhow, all the problem is asking is to plug in the values of time to find the height.
We see when time is zero, the height is 64 feet. Plug in zero for the "t" variable and you'll get 64 feet.
When the penny has dropped for half a second or 0.5 seconds, we know the "t" variable and plug in that value.
h = -16(.5)^2 + 64.
h = -16(.25) + 64.
h = -4 + 64.
h = 64 feet when the penny has dropped for half a second.
I encouraged student progression when given the knowledge to complete a problem. We know how to complete the rest of the table. Good luck!
