Answer:  The positive number is  \dfrac{1}{2}.

Step-by-step explanation:  We are given to find the positive number that is twice it's own square.

Let x denotes the required number.

Then, according to the given information, we have

x=2x^2\\\\\Rightarrow 2x^2-x=0\\\\\Rightarrow x(2x-1)=0\\\\\Rightarrow x=0,~~2x-1=0\\\\\Rightarrow x=0,~\dfrac{1}{2}.

Sine 0 is not considered as a positive number, so the required positive number is \dfrac{1}{2}.

Thus, the positive number is \dfrac{1}{2}.

andrezito [222]
The colony doubles every hour, the population is equal to
p = 2^t

<span>Where t </span><span>is the time in hours.</span>
We are able to see this because:
2^0 = 1
2^1 = 2
2^2 = 4

Notice that the x coordinate of the graph corresponds to the time, and the y coordinate corresponds to the population.

<span>Thus at t = 9
</span>p = 2^t
p = 2^9
p = 512.

The correct answer is 512.
