determine the rate of change of the water left in the pool with respect to the time.\ntime (min) water left in pool (gal)\n10 80\n20 60\n30 40\n40 20

Answer

Explanation:

Step1: Elegir dos puntos

Tomamos los puntos $(t_1, w_1)=(10,80)$ y $(t_2, w_2)=(20,60)$.

Step2: Aplicar la fórmula de la pendiente

La tasa de cambio (pendiente) $m$ se calcula como $m=\frac{w_2 - w_1}{t_2 - t_1}$. Sustituyendo los valores: $m=\frac{60 - 80}{20 - 10}$.

Step3: Realizar los cálculos

$m=\frac{- 20}{10}=-2$.

Answer:

-2 gal/min
