Answer:
Option A
Step-by-step explanation:
The complete question is attached here
The rate of increase of bacterial population be K
As we know

where Y is the final population. In this case it is 1000
K is the rate of increase of population i.e 3 times per hour
T is the time in hours
Y0 is the initial population = 5
Substituting the given values, we get -

Taking log on both sides, we get -
ln
= ln 

T = 2.084 hours
hence, option A is correct

Step-by-step explanation:
Answer:
x=30
Step-by-step explanation:
Find the value of x that will make A and B parallel
For A & B to be parallel, the interior angles must be supplementary, i.e.
4x+2x = 180
6x=180
x=30
When x=30, the interior angles are 120 and 60 which are supplementary.
The answer is A. multilpy 12×24 to get 288.subtract 24 from 32 to get 8, which is the leng th of the triangle. 12×8=96÷2=48. 48+288=336
