I need help with these three problems (college algebra)

Paraphin [41]

5. After 6 hours, the concentration is halved. After 12 hours, it will be quartered. If the original concentration is 200 nmol, a quarter is 50 nmol.

14. The population doubles after 3 hours, and a day is 24 hours. That means that the original population should be multiplied by $2^{24/3}$ , or $2^8$ . 3 million times $2^8$ is 3 * 256 million, or 768 million.

15. The concentration is halved every 8 hours and the original concentration is 100 nmol. So now, how many times do you halve 100 to get to 12.5?

100/2 = 50, 50/2 = 25, 25/2 = 12.5. That's three times. 3 * 8 is 24 hours, or 1 day.

G) (5y)^3= 125y^3

H) a^0 b (^0= 1 always) -> ab

Hope this helps!
