Answer: In 10 hours, 4000 bacteria will be present.
Step-by-step explanation:
Given that 2000 bacteria grew to 2400 in 2 hours,
growth/ increase rate = 2400 - 2000
= 400 bacteria increase in 2 hours
Per hour is therefore 400/2 = 200 bacteria increase per hour
If the bacteria increases by 200 per hour
If 200 = 1 hour
X = 10 hours
We cross multiply:
X = 200 x 10
X = 2000
Therefore, a culture with 2000 bacteria at the same growth rate will have increased by additional 2000 in 10 hours
So, after 10 hours, number of bacteria will be 2000 + 2000 = 4000 bacteria
First, simplify the equation into y=mx+b form. This would be y=3x/2-15/2. And for the slope of a line perpendicular to the original line, there is a trick. Their slopes should multiply to -1. For 3/2 to multiply to -1, you need -2/3.

Answer:
That can also be written as
60,000/10= 6,000
