Answer:
Step-by-step explanation:
we need to find first the marked down
25*12/100=3
the new price will be 25-3=22 dollars
In order to be differentiable everywhere, 
must first be continuous everywhere, which means the limits from either side as 
must be the same and equal to 
. By definition, 
, and
so we need to have 
.
For to be differentiable at 
, the derivative needs to be continuous at , i.e.
We then need to have
Then
9 = 3^2
Since 3 squared equals 9, that is how 9 as a power of the base 3 should be written.
Step-by-step explanation:
without seeing a picture I'm guessing 45 45, and 90
Answer:
answer is 90
if m^2=m^3
then, 90+90=180
