Answer:
1.309 I just I don't know
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.
Answer:
ahh pythagoras' theorem, my old nemesis...
Step-by-step explanation:
Divide the distance by the average speed to find the time. 30 miles 20.04 mph 1.497 hrs. So it would take about 1.5 hours.
Answer:
6x-18
Step-by-step explanation:
First we multiply everything in the parentheses by 3
3×2x=6x
3×(-6)=-18
And now we put it together-
6x-18
