The population has a size of 6 ,000 at t equal to zero and with t is in years.
00:06
And the population decreases by 250 each year.
00:09
Then what is the formula of p is a function of time? so the population p is a function of time is going to be 6 ,000, which is the initial population.
00:18
And in the first year, definitely it's going to decrease by 250.
00:23
In the, after the first year, this will be the population.
00:26
After the second year, the population will be 6 ,000 minus 250.
00:31
Minus 250 because it is again decreased by 250 so that can be written as 6 ,000 minus 250 times 2 likewise p 3 is going to be 6 ,000 minus 250 times 3 so p t after t years is going to be 6 ,000 minus 250 so this is the population t years for part a for part b that's going to be uh the population decreases by 11 % each year so so after first year, the population decreases by 11%.
01:11
It means that it was 6 ,000 initially.
01:14
And it decreased, so minus of 11 percentage of 6 ,000...
