Answer:
Step-by-step explanation:
14 = 1000 
.014 = 
ln(.014) = k ln(e)
k = -4.268
~~~~~~~~~~~~~~~~~~
after 3 hrs
1000 
0.00274
~~~~~~~~~~~~~~~
4 = 1000 
.004 = 
ln(.004)/-4.268 = t
t = 1.29368 hrs

Prob of getting 3 is 1/6, and prob of getting different odd number ie 1 or 5 is 2/6.
Answer:
(4b-9) (4b+9)
Step-by-step explanation:
16b^2 – 81
This is the difference of squares
(a^2 -c^2) = (a-c) (a+c)
a^2 = 16b^2 so a= 4b
c^2 = 81 so c = 9
(16b^2 – 81) = (4b-9) (4b+9)
