Un agricultor dispone de 450 m. De valla para cercar un terreno circular de radio r y uno rectangular cuyo lado menor es igual a
Colt1911 [192]

Answer:

Step-by-step explanation:

El gráfico de la región está adjunta. En la imagen, d corresponde al gráfico de diámetro del círculo. Sabemos, que tenemos un total de 450 metros de cerca. Luego, el perímetro de nuestra figura es de 450. Sabiendo que el perímetro de un círculo de radio r es 2\pi r. Tenemos la siguiente ecuación

\pi \cdot r + 2x + 2r = 450

De donde deducimos que

x = \frac{450-r(\pi+2)}{2}.

Así mismo, sabemos que el área de nuestra figura es  la suma del área del rectángulo (base por altura) más el área del semicirculo. Sea f(r) el área de la rigura. Entonces,

f(r) = \frac{\pi \cdot r^2}{2}+ 2\cdot r \cdot \frac{450-r(\pi+2)}{2} = \frac{\pi \cdot r^2}{2}+ r\cdot (450-r(\pi+2))

La función es una función cuadrática, ya que es un polinomio de grado 2 para la variable r. Con ayuda de un software de gráficas, podemos ver adjunta la gráfica de la función.

Labrador Retriever weighs 48 kg after a diet and exercise program the dog weighs 43 kilograms to determine if this shows a perce
ExtremeBDS [4]

Answer:

percentage change in weight ≈ 10%

Step-by-step explanation:

The dog weighed 48 kg after a diet and after an exercise program the dog had a weight of 43 kg. This means the dog loss weight since the dog weight decreased from an initial value of 48 kg to 43 kg. The decrease in weight can be calculate as

decrease in weight = original weight - new weight

original weight  = 48 kg

new weight = 43 kg

decrease in weight = 48 - 43 = 5 kg

Since the weight decrease their will be a percentage decrease in weight.

% decrease = decrease in weight/original weight × 100

% decrease = 5/48 × 100

% decrease = 500/48

% decrease = 10. 42666666667

percentage change in weight ≈ 10%
