Answer:
db / dt = kb
this becomes b(t) = Ce^(kt)
C = 100, the initial population
P(1) = 420 = 100 e^(1k)
4.2 = e^k
ln 4.2 = k
a) thus, b(t) = 100 e^(t ln 4.2)
b) b(3) = 100 e^(3 ln 4.2)
c) growth constant will still be ln 4.2 (constant percentage of populatioin)
d) 10000 = 100 e^(t ln 4.2)
100 = e^(t ln 4.2)
ln 100 = t ln 4.2
t = ln 100 / ln 4.2
Step-by-step explanation:
Answer:

Step-by-step explanation:
Triangle MAB is similar to triangle MNP
Since the triangles are similar, the corresponding ratios are in the same proportion.
Therefore we can write the relation;


This implies that;

We multiply both sides by 72.6 to get


Hence the value of
is 50.6 cm
Answer:
ans of y is 3 because 12-3=9
Answer:2(x+1/2x)+3=105
Step-by-step explanation: that is how i got my answer. If not a similar answer i would go with 2x+3=3x+105.
You can automatically eliminate the first answer. The second one has a random 5, so eliminated. and the last one just isn't correct.
