Answer:
1.21 g/day
Step-by-step explanation:
We start with the fact that
The mass of the bacterial colony (in grams) is described by

Where t=Time(in days)
Next, we differentiate with respect to t

Using the formula 


We know that P(t)=6
Now, substitute this value





Insert the given value of t


We understand that 
Applying the formula


By employing 
g/day
Consequently, the instantaneous rate at which the mass of the colony changes is=1.21g/day
Vanessa’s garden hose is capable of filling her backyard fish pond at a rate of 24 gallons per minute. With this rate, her pond will be filled up shortly.
If you want to rearrange p = r - c to express c, you can follow these steps:
p = r - c /+c
p + c = r - c + c
p + c = r /-p
p + c - p = r - p
c = r - p
The correct form is c = r - p.
