The question is an illustration of a number line, and the point located at -8.65 is B

<h3>How to determine the point?</h3>

From the complete question, we have the following highlight

Point B is between -8 and -9, and point B is closer to -9 than -8

No other point is between -8 and -9

So, we can conclude that the point located at -8.65 is point B

Given f(x) = 4x - 6 and g(x) = f(2x), write an equation for g.

AysviL [449]

f(x)=4x-6

g(x) = f(2x)

Substitute 2x into the first equation, which you get

f(2x)=8x-6

Research scientists need a certain type of bacteria to conduct an experiment. There are 2,500 bacteria in a certain culture. The

pychu [463]

Answer:

7 days

Step-by-step explanation:

At 25% per day, it will take approximately 3 days to double the population, so approximately 6 days for the population to quadruple. Checking that number, we find it is not quite enough for the experiment, so another day is required.

"Guess and check" as a method of solution works especially well if you have an automated checker to evaluate your guess. A graphing calculator or spreadsheet can work well for this.

_____

We guess 3 days as the doubling time using the "rule of 72" that says the product of percentage and doubling time is about 72. That is, 72/25 ≈ 3. (This is only a very rough approximation of doubling time, best for rates near 8%.)
