A scientist is observing bacterial population growth on a microscope slide. Initially there are 72 organisms. The scientist notes that the population triples every hour. What function, P(t), can she use to describe the changes in population as a function of time, in hours, t? Your equation should start with P(t)=

Step-by-step explanation:

We have to find an equation of the form , where a is the initial value, b is the rate, and x is the time.

Here, the initial amount if 72, so a = 72. We also know that the population triples every hour, which means b = 3. Plug these in:

72(3^t)

Step-by-step explanation:

In 1 hour,

72(3)

In 2 hours

72(3)(3) = 72(3)²

.

In t hours,

72(3^t)

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
