average rate of change practice\n1) what is the average rate of change on the interval 10, 30 for the following function?\ntime (mins) water left in pool (gal)\n10 80\n20 60\n30 40\n40 20

Answer

Explanation:

Step1: Identificar los valores

Sea $x_1 = 10$, $y_1=80$, $x_2 = 30$, $y_2 = 40$.

Step2: Aplicar la fórmula de tasa de cambio promedio

La fórmula de la tasa de cambio promedio de una función en el intervalo $[x_1,x_2]$ es $\frac{y_2 - y_1}{x_2 - x_1}$. Sustituyendo los valores: $\frac{40 - 80}{30 - 10}=\frac{- 40}{20}$.

Step3: Simplificar la expresión

$\frac{-40}{20}=-2$.

Answer:

$-2$
