All of these only require a single operation before you get x alone. for example:
x - 2 = 6
compared with
2x = 6
for the first one, you add two and get x = 8. for the second one, you divide by 2 and get x = 3. they're both a single step, as the name "one-step" equations tells you, and you only have to divide, multiply, add, or subtract one value.
<h2>-0.71 is it i think so i dk </h2>
(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 
.
There is no square root of five...
Answer:
That equation is (2.5×2). The mean of the K is ×2
