Explanation: the difference between the numbers is the same
Answer:
Step-by-step explanation:
The formula is
![y=45(4)^x](https://tex.z-dn.net/?f=y%3D45%284%29%5Ex)
which models the exponential function
where a is the initial amount of whatever it is you have (in our case it's bacteria), b is the growth rate (ours is 4 which means that every day the number from the day before increases by a factor of 4), and x is the number of days. We plug into the formula the values we have, starting with x = 1:
![y=45(4)^1](https://tex.z-dn.net/?f=y%3D45%284%29%5E1)
Always raise what's inside the parenthesis first, then multiply in the 45. 4 to the first is 4, and 4 multiplied by 45 is 180. After the first day, there are 180 bacteria present in the culture.
Next, x = 2:
which simplifies to
y = 45(16) so
y = 720.
Next, x = 3:
which simplifies to
y = 45(64) so
y = 2880
