Answer:
£4116.
Step-by-step explanation:
Each year the car is worth (100-30) = 70% or 0.70 of its worth the previous year.
At the start of 2017 the car was 3 years old.
The equation to work out its value is
V = A(0.70)^t where A is 12,000, t = the number of years.
So we have, at the start of 2017:
V = 12,000 (0.70)^3
= £4116.

Answer:
A las 15:00 horas la temperatura será de -15ºC, habiendo subido 12ºC desde el corte de luz.
Step-by-step explanation:
Dado que en un frigorífico la temperatura es de -27 °C, y después de un corte de luz a las 12:00 horas, la temperatura empieza a subir 2 °C cada media hora, para determinar cuál es la temperatura a las 15:00 horas, y cuánto ha variado la temperatura desde el corte de luz, se deben realizar los siguientes cálculos:
((15 - 12) x 2) x 2) - 27 = X
(3 x 2 x 2) - 27 = X
(6 x 2) - 27 = X
12 - 27 = X
-15 = X
Por lo tanto, a las 15:00 horas la temperatura será de -15ºC, habiendo subido 12ºC desde el corte de luz.
