Suppose the number of bacteria are increasing exponentially, We can model the number of bacteria at a given time t, using the formula:
f(t)=ae(tk)
where, k=constant of proportionally and a=initial number;
thus;
f(t)=2000e(0.005t)
Therefore the population after 12 hours will be:
f(12)=2000e^(0.005*12)
f(12)=2,123.67=2,123 bacteria
Answer:
x is 7 8
Step-by-step explanation:
y is 5 6
Answer is 40km
Explanation:
So in this question we can use a proportion
Since
28km is 70% we can write it equal to 70%
28=70
and since 100% is unknown we can write it equal to x
100=x
Then we put it in proportion form
28/x=70/100
Then cross multiply and divide
28(100)/70=x
Which would equal 40
Multiply 2 and 3 also multiply 4 and 5 and then divide the products together like so 2x3 divided by 4x5 so 6 divided by 20
analyze problem
no need for distance formula
same x, only need to subtract y
3a-0=3a
