Mientras un avión vuela hacia el Este a 120km/h, también es arrastrado hacia el norte por un viento de 45km/h. ¿Cuál es la velocidad resultante de avión?​

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
