Y=4 (x+ 17/8)^2 - 657/16 hope this helps you out mate =)
Answer:
3072
Step-by-step explanation:
The number of cells is initially 3 and is multiplied by 2 every time t increases by 1/2 hour. This means the exponential function describing the number of cells can be written ...
y = (initial value) × (growth factor)^(t/(growth period)
y = 3 × (2^(t/(1/2)) = 3×2^(2t)
After 5 hours, the number of cells will be ...
y = 3×2^(2·5) = 3×2^10 = 3×1024
y = 3072
There are 3072 cells in 5 hours.

<em>Additional comment</em>
The function could be simplified to ...
y = 3×4^t
Answer:
-31.77
Step-by-step explanation:
95.31/3 since each ticket is the same amount.
This gives you 31.77, which is the price of 1 ticket.
Her balance would still be negative, so change 31.77 to -31.77
