Hello students.
00:01
Today we will discuss about this question.
00:04
In this question we are given that a cta has a current population here.
00:11
Current population that is equals to 500 -3 -0 people and grows at a rate of 2 percentage per year.
00:35
That is equals to 2 -0 -3 -0 and grows at a rate of 5 percentage per year.
00:44
It is for cta and this will be for ctvb.
00:49
Now here we need to find when will the cities have the same population.
01:00
So here we need to find t that is equals to question mark.
01:05
And in part b, we need to find, suppose a ctc has a current population of y0 is less than 5 ,500, triple zero, and the growth rate of p is greater than 2 percentage per year, then we need to find the relationship between relation between y0 and p such that the cities a and b have the same population in 10 years.
01:49
So here first of all, in part a, we can write for citi a that p .a that is equal to 500 -3 -0 in bracket 1 plus 2 divided by 100.
02:06
Raised to t so that is equals to 5 -0 -3 -0 multiplied by 1 .0 to raise to t and for c t b we can write p b that is equals to two double zero triple zero multiplied by one plus five divided by hundred raised to t so that is equals to 2 -0 -3 -0 multiplied by 1 .05 raise to t.
02:37
Now we can write we will equate this both equations so therefore 5 -0 -3 -0 1 plus 0 2 raise to t that is equals to 2 -0 -3 -0 -0 .0 .1 .05 raised to t so that implies that 5 divide by 2 that is equals to 1 .05 divided by 1 .05 divided by 1 .0...
