Ответ:
It is a 90 degree angle, so you have to subtract 38 from 90 to find the complementary angle. This turns out to be 52. Because it is 2x, you need to find out what multiplied by 2 equals 52. So it is then basic algebra. 2x=52. The final answer is 26
Ответ:
3600 bacterias
Step-by-step explanation:
From P = P'e^(-kt), where
P = final population
P' = initial population
k = decay constant
t = time in hrs
Substituting we have
200 = 170000 x e^(-42k)
1/850 = e^(-42k)
We take natural log (Ln) of both side
Ln (1/850) = Ln (e^(-42k))
-6.745 = -42k
k = 0.16059.
For amount remaining after 24 hrs we find P
P = 170000 x e^(-0.16059x24)
P = 170000 x e^-3.85416
P = 170000 x 0.02119 = 3602.3
Approximately 3600 bacterias.
