Answer:
E. 2700.
Step-by-step explanation:
There are 3 possible values for the first digit ( V, X or P)
The second and third have 10P2 = 10!/(10-8)! = 90 possible values.
The third digit - there are 10 possibilities
So the answer is 3 * 90 * 10
= 2700.
Answer:
65
Step-by-step explanation:
You can use f(15) = 40 to solve for C, then find f(0), the initial temperature.
40 = f(15)
40 = Ce^(-0.045·15) +14 = .50916C +14
26 = .50916C
26/.50916 = C ≈ 51.065
Then f(0) is ...
f(0) = 51.065·e^0 +14 = 65.065 ≈ 65
The initial temperature of the water was 65 degrees Fahrenheit.
