The answer is 104.4 because 38+65 is 103. then you add the decimal part of the equation which is 37. If you are rounding to the nearest tenth it would be 104.4
Answer:-7 if you allow complex numbers is in the domain of f of g. It is not in the domain if you disallow complex values
Step-by-step explanation:the domain is the set of x variables that produce a value for y. If you plug in -7 for x you get a negative value in the radical producing an imaginary number. If you allow complex values then x is in the domain. Otherwise it is not
Answer: 0
Step-by-step explanation: it said round to the nearest hundredth when you just need 0.21 so 0.21 rounded to the nearest hundredth is going to be 0.
Answer:
w = 54°
Step-by-step explanation:
The inscribed angle w is half the measure of its intercepted arc, that is
w = 
× 108° = 54°
Answer:
Step-by-step explanation:
The rate of change in the temperature T of coffee at time t is written as 
(remember derivatives are used to express rates of change, and in our case the rate of change of the temperature T). The difference between the temperature M of the air at time t, and the temperature T of the coffee at time t can be expressed as 
Saying that the rate of change in the temperature T is proportional to the difference between M and T is just a way of saying that the rate of change in the temperature T is equal to the difference between M and T, multiplied by some constant k (whose value we don't know, but still that's what it means).
Therefore we get
