Answer:
a)
: at time t = 2 minutes the temperature will be 8.265 degress
b)
: the temperature will be 6 degrees at time t = 3.55 minutes.
Step-by-step explanation:
When dealing with temperature changes, it's best to work with Newton's Law of Cooling.

here:
: the temperature in the room.
: ambient (or outdoor) temperature (that always remains constant, in our case:
)
: are constants
Our conditions are provided:
1) 
2) 
using the first condition

using the second condition:

we can use our calculated value of C to find k

Finally we can put these constants back in the main equation:

or 
a) Reading after one more minute?
so it's asking:
T(2) = ?

Hence, after one more minute the temperature of the room will be 8.267 degrees
b) When will it be 6 degrees?
T(t) = 6?

Hence at t = 3.55 minutes the temperature of the room will be 6 degrees.
<u>Answer:</u>
P = 61.9°
<u>Step-by-step explanation:</u>
We are given a right angled triangle, ΔPQR, with known side lengths for all three sides and we are to find the measure of angle P.
For that, we can use sin, cos or tan.



P = 61.9°
