With the order of operations, you must do the division (18/9) first.  Then do the square root.  Then do the subtraction.

\begin{aligned}\dfrac{18}{9} - \sqrt{81} &= 2-\sqrt{81}\\[0.5em]&=2-9\\[0.5em]&=-7\end{aligned}

Please help 1. another term for adding money to an account is
zzz [600]
<span>Payment. While payment is the sum of money paid in exchange for something either goods and services; the money can be credited (or added) into an account directly without making direct payment. We can also credit our account which is also payments. The most efficient way of building a savings is having a set minimum or percentage for saving whichever is greater. Sometimes we may need to save more than our "set minimum" especially when we earn more. The higher we earn the more our set minimum pales in comparison to what we ought to save. On the other hand if we have a set percentage it would also need to be raised higher when we earn more, but saving whichever is greater ensures that we make the best and most efficient savings decision at any period in time.</span>

Not sure why such an old question is showing up on my feed...

Anyway, let x=\tan^{-1}\dfrac43 and y=\sin^{-1}\dfrac35. Then we want to find the exact value of \cos(x-y).

Use the angle difference identity:

\cos(x-y)=\cos x\cos y+\sin x\sin y

and right away we find \sin y=\dfrac35. By the Pythagorean theorem, we also find \cos y=\dfrac45. (Actually, this could potentially be negative, but let's assume all angles are in the first quadrant for convenience.)

Meanwhile, if \tan x=\dfrac43, then (by Pythagorean theorem) \sec x=\dfrac53, so \cos x=\dfrac35. And from this, \sin x=\dfrac45.

So,

\cos\left(\tan^{-1}\dfrac43-\sin^{-1}\dfrac35\right)=\dfrac35\cdot\dfrac45+\dfrac45\cdot\dfrac35=\dfrac{24}{25}
