Answer:

Step-by-step explanation:
The amount of integers between
and
inclusive is always
.
This means the amount of integers Michael wrote is
. Because
, which gives
,
is always non-negative. So, we can kick out the absolute value sign to get
.
So, he wrote
integers and we're done!
Answer:
k = log9 / log 0.66
k = 5.3
Step-by-step explanation:
Please always remember that, when an exponential equation is given with different bases, the best approach is to take log of both sides.
If you have a calculator handy, that would be pretty fast and easy.
0.66 ^ k = 9
Take log of both sides:
klog 0.66 = log 9
k = log 9 / log 0.66
k = 0.954 / - 0.18
k = -5.3
Maths is fun, let's keep learning
2m
I think it is because the down it is 8 m
so there is 6m it the top
so it should be
8-6=2
