Answer:
(a) 13.85 °C
Step-by-step explanation:
The temperature difference is a decaying exponential function of time. Here, it decreases from an initial difference of 15 °C to 10 °C after 25 minutes. So, that temperature difference can be modeled as ...
ΔT = 15(10/15)^(t/25)
We want to find the value of this at t=55. It is ...
ΔT = 15(2/3)^(55/25) ≈ 6.15
This is the amount the temperature of the drink is below room temperature.
drink temperature = (20 - 6.15) °C = 13.85 °C
The temperature of the drink after 55 minutes is about 13.85 °C.

Igualar con cero
Doble derivada de la función
Entonces, la función es máxima cuando el número de unidades vendidas, ,
-1/3
really? it's that easy dude.
whatever number is next to x, like say, 3x, that number would be the slope, so it would be 3.
hope it helped.
it is definitely the answer B
