Hi there, I'm new to this.
Could someone please point me in the right direction in answering this worded question?
A newly formed metal ingot cools from a temperature of 800 degrees Celsius one minute after being poured to a temperature of 600 degrees Celsius five minutes after being poured. The temperature, T degrees Celsius, of the metal at time (t) minutes after the ingot was formed is given by
T=k 10^(-at) (k and a are constants)
a) Find the temperature of the metal at the moment the ingot was poured.
b) Find the value of a (correct to 5 decimals places)
Any help would be appreciated, thanks
