One shift down three shift right so 1 down 3 right
For this case we have a function of the form:

Where,
A: initial population of bacteria
b: growth rate
x: number of hours
Since the diameter is double every hour, then:

We must now look for the value of A.
To do this, we evaluate an ordered pair of the graph:
For (1, 2):

Clearing A we have:


Then, the function is given by:

For after 9 hours we have:

Answer:
the diameter of the bacteria after 9 hours is:

Hello,
The sum of volumes of the two spheres is
4/3*π*a³+4/3*π*b³=4/3*π*c³
c=∛(a³+b³)=∛(3³+5³)=∛152=5.336803297...≈5.34 (cm)
Which figure shows the correct dimensions of a 1414 scale drawing of the given figure?
