- the graph represents the amount of water in a fish - tank as a function of the time since brian started draining it. find and explain the meaning of the indicated values in terms of the context.
a. f(0)=
explain its meaning in the graphs context.
b. f(2)=
explain its meaning in the graphs context.
c. when f(x) = 0, then x=
explain its meaning in the graphs context.
Explicación:
Paso 1: Definir la fórmula de la pendiente
La fórmula para calcular la pendiente $m$ entre dos puntos $(x_1,y_1)$ y $(x_2,y_2)$ es $m=\frac{y_2 - y_1}{x_2 - x_1}$.
Paso 2: Calcular la pendiente para los puntos (-8,3) y (2,9)
Tomando $x_1=-8$, $y_1 = 3$, $x_2=2$ y $y_2 = 9$, sustituimos en la fórmula:
$m=\frac{9 - 3}{2-(-8)}=\frac{6}{2 + 8}=\frac{6}{10}=\frac{3}{5}$
Respuesta:
$\frac{3}{5}$
