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

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

answer:

125 yards

explanation:

75+50=125. that is my answer
