Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{d = 6}}}}}

Step-by-step explanation:

\sf{3d + 9 = 27}

Move 9 to right hand side and change its sign

\dashrightarrow{ \sf{3d = 27 - 9}}

Subtract 9 from 27

\dashrightarrow{ \sf{3d = 18}}

Divide both sides by 3

\dashrightarrow{ \sf{ \frac{3d}{3}  =  \frac{18}{3}}}

Calculate

\dashrightarrow{ \sf{d = 6}}

Hope I helped!

Best regards! :D

Answer:

d = 6

Step-by-step explanation:

3d + 9 = 27

Subtract 9 from each side

3d + 9-9 = 27-9

3d = 18

Divide each side by 3

3d/3 = 18/3

d = 6

Which function can be used to find the number of cells of bacteria in the population at time t
Nonamiya [84]

Answer:

db / dt = kb  

this becomes b(t) = Ce^(kt)  

C = 100, the initial population  

P(1) = 420 = 100 e^(1k)  

4.2 = e^k  

ln 4.2 = k  

a) thus, b(t) = 100 e^(t ln 4.2)  

b) b(3) = 100 e^(3 ln 4.2)  

c) growth constant will still be ln 4.2 (constant percentage of populatioin)  

d) 10000 = 100 e^(t ln 4.2)  

100 = e^(t ln 4.2)  

ln 100 = t ln 4.2  

t = ln 100 / ln 4.2
