Answer:
Here you go .........
Step-by-step explanation:
the temperature is lowered in an arithmetic progression. so we can apply formulae of an arithmetic progression.
initial temperature = a = 40°C
common difference d = -5°C per hour
after 10 hours temperature =
= a + (n-1)d
n = 10hours = 10
a = 40 + (10-1)(-5)
= 40 -45
= -5°C
Therefore the temperature after 10hours = -5°C
