marin [14]

Answer:

in 630 minutes, the population of the bacteria  will  64,000

Step-by-step explanation:

current population of the bacteria = 8,000

and this population doubles every 210 minutes

0 (minute) ------------------------ 8,000 bacteria

210 + 0 (210 minutes) -------------------- 2 x 8,000 = 16,000 bacteria

210 + 210 ( 420 minutes) -------------------- 2 x 16,000 = 32,000 bacteria

420 + 210 (630 minutes) -------------------- 2 x 32,000 = 64,000 bacteria

Therefore, in 630 minutes, the population of the bacteria  will  64,000

This is my question pls help
Cerrena [4.2K]

Answer:

a = 15

Step-by-step explanation:

Substitute b = 12 , a = 9 into the equation

12 = \sqrt{a^2-9^2}

12 = \sqrt{a^2-81} ← square both sides

144 = a² - 81 ( add 81 to both sides )

225 = a² ( take square root of both sides )

± \sqrt{225} = a , then

a = ± 15

a > 0 , so a = 15
