Answer:
Step-by-step explanation:
given that a bacteria culture initially contains cells and grows at a rate proportional to its size.
If P be the size then growth rate
where k is constant of proportionality
separate the variables as
If after 1 hour population is B (say)
then k = ln B - ln A
Using this
P(t) = 
b) P(e) = 
c) Rate of growth = 
Unless you give B value, d cannot be solved
1. s=6
2. z=16
3. t=2
4.n=98
5.r=-1.8
6.w=74/45
Hope these are correct
Let l = the lentth of the rectangle and w = the width of the rectangle; where w>0 and l>0;
We have 84 = l x w and l = 2 + w;
84 = (2+w) x w;
We solve the equation: w^2 + 2w - 84 = 0;
We obtain the solution w = 8.21;
The perimeter of the triangle is is 3 x 8.21 = 24.63;
Type it in the calculator and there is your answer
Answer:
120
Step-by-step explanation:
If you multiply these numbers you will eventually find that they all have a common multiple of 120. 120 is also the least common multiple so therefore, the lcm is 120
