9514 1404 393

Answer:

  6.2

Step-by-step explanation:

We presume your "k-value" is the k in the exponential decay term ...

  e^(-kt) . . . where t is the number of time units

This is 1/2 when ...

  ln(1/2) = -kt

  t = ln(1/2)/(-k) = ln(2)/k

  t = 0.69315/0.1124 ≈ 6.2

The half life is about 6.2 time units.

What is bigger, 29/40, 7/10 or 3/5
Romashka-Z-Leto [24]
Place each fraction under a common denominator. Remember, the number you multiply to the denominator must also be multiplied to the numerator

29/40 = 29/40
7/10(4/4) = 28/40
3/5(8/8) = 24/40

As seen by the fractions above, the order is 24/40, 28/40, and 29/40, <em>or</em> placed in it's original form is 3/5, 7/10, 29/40.

29/40 is the greatest, and is your answer

hope this helps
