Answer: D. 6=6
Step-by-step explanation:
9x + 6 =3(3x+2)
9x + 6 = 9x +6
9x - 9x +6 = 6
0x +6=6
6=6
Answer:
false
Step-by-step explanation:
I'm not really sure
I believe the answer would be 18,618
25,600/11= 2,327
2327*8= 18,618
hope this helped

Answer:
Step-by-step explanation:
Given that,
Cells are divided into two cell every 20mins, this implies that the half-life is 20mins
Initial population growth is 60cells
Growth rate r?
Population growth is modeled as
P(t) = Po•exp(rt)
Where,
Po is the initial growth at t= 0
Po= 60
P(t) is population at any time t.
Since the population doubles every 20mins(⅓hr)
Then, P(⅓) = 2×60 =120
Then, P(t) = 120cells
So, applying the formula
P(t) = Po•exp(rt)
120 = 60•exp(⅓r)
120/60 = exp(r/3)
2 = exp(r/3)
Take In of both sides
In(2) = r/3
Cross multiply
r = 3In(2)
r = 2.079 /hour
The growth rate is 2.079/hour.
