Answer:

x = -(1 + 4i)

or x = -1+4i

Step-by-step explanation:

From what we have;

-(x + 1)^2 = 4

(x + 1)^2 = -4

x + 1 = √-4

x + 1 = -4i or 4i

x = -1 - 4i or -1 + 4i

It is observed that a certain bacteria culture has a relative growth rate of 15% per hour, but in the presence of an antibiotic

wel

Answer: 110 in the presence of no antibiotic, 53 in the presence of an antibiotic

Step-by-step explanation:

So first we are told the growth rate of a bacteria culture is 15% and the number of bacteria in the culture is 24

So we find 15% of 24

15/100 x 24 = 18/5

So 18/5 bacteria is produced every hour, then for 24hours

18/5 x 24 = 86.4

The number of bacteria is already 24 as said

So altogether

86.4 + 24 = 110.4 approximately 110

Then, for the presence of antibiotic, the growth rate is 5%

So 5% of 24

5/100 x 24 = 6/5

So 6/5 bacteria is produced every hour

For 24hours

6/5 x 24 = 28.8

Initial culture = 24

Final culture = 24 + 38.8 = 52.8 approximately 53
