Question

The relationship between a bacteria population p, in thousands, and time d, in days, since it was measured to be 1,000 can be represented by the equation. Select all statements that are true about the situation. © 2019 Illustrative Mathematics. All Rights Reserved. Select all that apply:A: Each day, the bacteria population grows by a factor of 2B: The equation p=2^d also defines the relationship between the population in thousands and time in daysC: The population reaches 7,000 after log2(7,000) daysD: The expression log2(10) tells us when the population reaches 10,000. E: The equation d=log2(p) represents a logarithmic functionF: The equation 7=log2(128) tells us that the population reaches 128,000 in 7 days

Answer 1

d = log₂p represents a logarithmic function, The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

What is an exponential function?

An exponential function is in the form:

y = abˣ

Where a is the initial value of y and b is the multiplication factor.

Let p represent the bacteria population in thousand after d days.

Since each day, the bacteria population grows by a factor of 2, hence:

$p=2^d$

Hence, d = log₂p represents a logarithmic function

The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.
