There are bacteria in a petri dish. After 20 minutes, every bacterium splits into two. Explain how you can use the properties of exponents to write an expression for the resulting number of bacteria.

Step-by-step explanation:

Given

Bacteria splits to 2 at every 20 minutes

Required

Explain how to get the resulting number of bacteria

To do this we simply make use of geometric progression formula;

In this case; r = 2 (rate at which they split);

a represents the initial number of bacteria in the dish

Apply law of indices

Assume, we want to determine the number of bacteria at the 10th 20 minutes (in other words, 200 minutes), the value of n will be 10

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5
