Need Help with finding half life or doubling time

Mathematics
1 answer:
adell [148]3 years ago

Answer:

12.2 hours

Step-by-step explanation:

You want to find t such that y = 2·y₀. That is, you want to solve

... 2y₀ = y₀·e^(0.0567t)

Dividing by y₀, you have

... 2 = e^(0.0567t)

and taking the natural log gives ..

... ln(2) = 0.0567t

... ln(2)/0.0567 = t ≈ 12.2248 . . . . divide by the coefficient of t

The doubling time is approximately 12.2 hours.

Answer:

#1. Identity #2. 0 #3. No solution

Step-by-step explanation:

#1.

5y + 2 = (1/2)(10y+4)

5y + 2 = 5y + 2

This would be identity as the equation of the left and right are the same. This is not to be confused with no solution(explained below).

#2.

0.5b + 4 = 2(b+2)

0.5b + 4 = 2b + 4

0.5 b - 2b = 0

b = 0

#3.

-3x + 5 = -3x + 10

This equation has no solution because when you try to bring the -3x to one side, the x variable itself gets eliminated. So, how is it different from identity? Well in the first equation, it is true that when we try to bring the 5y one side it eliminates the y variable, however, that is also true for the constants(since if we try to bring the 2 to one side, it will be 2-2 which will equal 0, thus eliminating each other), but in this case, even if we remove the x, the constants will not equal 0, thus it will have no solution.
