Decide if it would be more appropriate to make an estimate or to do an exact calculation in each situation. Give your answer and specify if the number represents an estimate or a calculation. You are calculating a tip on a restaurant bill. The service was good, so you would like to tip about \( 20 \% \) of \( \$ 43 \). Part A: Is the answer an estimate or calculation? Answer: Calculate Part B: How much do you plan to tip? Answer: \( \$ \)

Given \( g \) and \( h \) as defined below, determine \( g+h, h-g, g h \), and \( \frac{h}{g} \). Using interval notation, repa the domain of each result. \( g(x)=\frac{-x-11}{x^{2}-100} \) and \( h(x)=\frac{-7 x-2}{x^{2}-100} \) (a) \( (g+h)(x)=\square \) Domain of \( (g+h)(x): \square \) (b) \( (h-g)(x)=\square \) Domain of \( (h-g)(x): \square \) (c) \( (g h)(x)=\square \) Domain of \( (g h)(x): \square \) (d) \( \left(\frac{h}{g}\right)(x)=\square \) Domain of \( \left(\frac{h}{g}\right)(x): \square \)

Simplify \[ \left(6 x^{3}+29 x^{2}+41 x+15\right) \div(2 x+5) \]
