(i) Yes. Simplify 
.
Now compute the limit by converting to polar coordinates.
This tells us
so we can define 
to make the function continuous at the origin.
Alternatively, we have
and
Now,
so by the squeeze theorem,
and approaches 1 as we approach the origin.
(ii) No. Expand the fraction.
and 
are undefined, so there is no way to make continuous at (0, 0).
(iii) No. Similarly,
is undefined when 
.
Answer: x=26-14
Step-by-step explanation :you need to subtract on both sides so that why it is x=26-14.
If im doing right....
100,000*.5=50,000
Then 12,000+50,000=62,000 per year.

Substitute for x.
g(20)= 2(20-4)
g(20)=32.
x=32.
