Cuando se usa una escalera para colgar un cuadro, ésta se apoya sobre la pared en un punto que está a una altura de 2 metros, y en el suelo en un punto que está a 3 metros de la pared, ¿Cuánto mide la escalera?

\( 36 x ^ { 2 } - 49 \square \)

\( q ( x ) = \frac { \csc x } { e ^ { x } } - e ^ { - x } , \quad a = \frac { \pi } { 6 } \)

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: \( \$ \)
