Math 30 points will give brainliest pls

exponential growth is

we need to find a and b

in form (x,y) we have the points

(0,20), (1,30), (2,45)

subsituting we get

, 45=ab^2[/tex]

if we look at the first one

so a=20

if we put that into the 2nd one

, so b=30/20=3/2

so the formula is

at 11 weeks, x=11

so about 1730 at the end of the 11th week

Every week, the population grows by half of its current population:

So, growing by half means to multiply by 1.5. And as you can see, we start with 20. By the end of week 1 we have multiplied by 1.5 once, by the end of week 2 we have multiplied by 1.5 twice, and so on.

So, at the end of the n-th week, we will have multiplied by 1.5 n times, leading to a population of

where p is the population and w is the number of weeks passed.

So, at the end of the 11-th week, the population will be

which is rounded by 1730

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
