A scientist used the function B(t) = 1850(0.75)^t to show the amount of bacteria present in a specimen jar t minutes after being in the freezer. Which statement explains the meaning of the 1850?

• 1850 is the rate at which bacteria multiply.

• 1850 represents the maximum capacity of the jar.

• 1850 indicates the temperature of the freezer.

• 1850 is the initial amount of bacteria present in the specimen jar.

A scientist used the function B(t) = 1850(0.75)^t to show the amount of bacteria present in a specimen jar t minutes after being in the freezer. Which statement explains the meaning of the 0.75?

• 0.75 represents the bacteria population doubling each minute.

• 0.75 indicates that the bacteria population remains constant over time.

• 0.75 indicates that the bacteria population decreases to 75% of its previous amount each minute.

• 0.75 shows that the bacteria population increases by 25% each minute.
