A population of rabbits doubles evey 4 months. if the population starts out with 8 rabbits how many rabbits will there be in 1 y
Airida [17]
If it doubles in every 4 months, then in 1 year it will double by 12/4 = 3 times.

So, the expression would be: n³
n = number of rabbit at starting point = 8

So, after 1 year, it would be = 8³ = 512

So, your final answer is 512

Hope this helps!

Two positive integers have a sum of 21 and a product of 108. what are the integers
Vitek1552 [10]
X= first integer
21-x= second integer

(x)(21-x)= 108
multiply x by each term in parentheses

21x - x^2= 108
subtract 108 from both sides

21x - x^2 - 108= 0
-x^2 + 21x - 108= 0
multiply whole equation by -1 to eliminate the negative coefficient in the first term

(-1)(-x^2 + 21x - 108)= 0
x^2 - 21x + 108= 0
factor (remember we need #s to add to 21 and multiply to 108)

(x-12)(x-9)= 0

x-12= 0
x= 12

x-9= 0
x= 9

CHECK:
9 + 12= 21
9 * 12= 108

ANSWER: The two positive integers that add to 21 and multiply to 108 are 12 and 9.

Hope this helps! :)
