Step-by-step explanation:
None of these,
a(under root),a, a(square)
this is the correct answer
Answer:

Step-by-step explanation:
The population of a community is known to increase at a rate proportional to the number of people present at time t.
This means that the population growth is modeled by the following differential equation:

Which has the following solution:

In which P(t) is the population after t years, P(0) is the initial population and r is the growth rate.
The population has doubled in 10 years
This means that
. We use this to find r.







So the equation that will estimate the population of the community in t years is:

I think it’s B. 7.50+1.50x<_15
Answer:
<em>x = 70</em>
Step-by-step explanation:
Isn’t it 26... cuz 26x2 is 52 then subtract 7 which is 45
