It looks like the differential equation is

Check for exactness:

As is, the DE is not exact, so let's try to find an integrating factor <em>µ(x, y)</em> such that

*is* exact. If this modified DE is exact, then

We have

Notice that if we let <em>µ(x, y)</em> = <em>µ(x)</em> be independent of <em>y</em>, then <em>∂µ/∂y</em> = 0 and we can solve for <em>µ</em> :

The modified DE,

is now exact:

So we look for a solution of the form <em>F(x, y)</em> = <em>C</em>. This solution is such that

Integrate both sides of the first condition with respect to <em>x</em> :

Differentiate both sides of this with respect to <em>y</em> :

Then the general solution to the DE is

Answer:
96.04 ft
Step-by-step explanation:
nutiply 9. 8 by 9.8
Breaking apart means that you just take the tens from each number, and the ones from each number, then add them up.
The tens from your numbers are:
30 from 34
40 from 45
The ones from your numbers are:
4 from 34
5 from 45
Now, you have to add up the tens and ones separately.
30 + 40 = 70
4 + 5 = 9
Finally, you add up those 2 numbers that you got- 70 and 9
