The population of the nanobots follows the equation
We must find the value of t such that the population of nanobots is 106 or more, that is
We'll solve the equation
Dividing by 5
Taking logarithms
By logarithms property
Solving for t

Answer D
The activity pictured is called goat tying.
Add 13 to both sides, which leaves you with k=42.
Remember that the difference between census and a sample survey is that in a census you take all the people of population in consideration in the study, and in the sample survey you take a part of that population in consideration to survey.
SO here if you check the problem it says that "in a recent poll, Pew reserchers found that 47% OF AMERICAN ADULT RESPONDENTS"
that is the population of the study that you want to focus, but there are a billion of american adult in US right? so its impossible that this company Pow Research made a census if you consider that a billion of people in US is almost infinite number for a company with a finite number of employees.
Also remember that a company has a budget to consider every month or every year, so to make a census or a sample survey it takes time and money, just to survey 10 people in a streeth of US cost money so if you want to reduce cost you might need to do a sample survey instead of a census.
