Answer:
38,400 bacteria
Step-by-step explanation:
Because there are 24 hours in a day, it will double 4 times
2400times 2 equals 4800 (1st)
4800 times 2 equals 9600 (2nd)
9600 times 2 equals 19200 (3rd)
19200 times 2 equals 38400 (4th)
Knowing the amount doubles every 30 days, we'll have to find how many times it'lll double in the 210-day time frame:
210 / 30 = 7
It doubles 7 times. If we were to write a rough, not worked on expresion representing that, knowing the starting population was of 20, we would write:
(((((((20 * 2) * 2) * 2) * 2) * 2) * 2) * 2) = 2560 rabbits
Hope it helped,
Happy homework/ study exam!
<h2>Number of bacteria after 6 days is 2313</h2>
Step-by-step explanation:
Population after n days is given by
Initial population, P₀ = 1000
Increase rate, r = 15 % = 0.15
Number of days, n = 6
Substituting
Number of bacteria after 6 days = 2313
Step-by-step explanation:
A=2πr(r+h)
A=6.28×14mm(+29mm)
A=77.92(14mm+29mm)
A=77.92×43
A=3350.56 mm

Answer:
z = 18.5
Step-by-step explanation:
2(4z − 6 − 6) = 170 − 46
2(4z - 12) = 124
8z - 24 = 124
8z = 148
z = 18.5
