Given the graph which <span>shows the population of a bacteria in an experiment, measured every hour.

The graph is a graph of an exponential function.

An exponential function is given by
f(t) = a(r)^t
where: a is the initial value of the function when t = 0,
r is the growth/decay rate, and
t is the time elapsed.

From the graph, the initial size of the population when t = 0 is 10, thus, the value of a in the function is 10.

Also, from the graph, after 2 hours, the popolation of bacteria was 20,
i.e.
20=10(r)^2 \\  \\ r^2=2 \\  \\ r= \sqrt{2} =1.4

Therefore, the </span><span>function representing the population of the bacteria after t hours is
f(t)=10(1.4)^t
</span>

Two similar prisms have heights 4 cm and 10cm what is the ratio of their surface areas
Slav-nsk [51]
Let k be the scale factor relating two similar prisms P_{1} and P_{2}, such that for corresponding parts of prisms P_{1} and P_{2} (for heights, in particular) we have k= \frac{height\  of \ P_{1} }{height \ of\  P_{2} }. In our case k= \frac{4}{10} = \frac{2}{5}.
For surfaces area we have \frac{Surface \ area \ of \  P_{1} }{Surface \ area \ of \  P_{2}} = k^{2} =( \frac{2}{5} )^{2}= \frac{4}{25}.
So, the right answer is 4:25 (choice B)
