When the temperature of the coffee reaches 140oF, it is cooling at a rate of 1oF per minute. When does this occur (in other words, how long does it take for the coffee to reach a temperature of 140oF)

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
