are those decimals or did you put periods instead of commas?
Step-by-step explanation:
Step-by-step explanation:
Let X = the number of days.
For growth rate,
y = X° × rate of growth, k
Where,
X° = initial amount of bacteria
k = rate of growth per day
Colby = 50 bacteria
kc = 2^(24/2 × X)
y = 50 × 2^(12X)
Jaquan = 80 bacteria
kj = 2^(24/3 × X)
y = 80 × 2^(8X)
