Need help with 14 and 2 ASAP
Elan Coil [88]
Let's start with 14, shall we? Alright, so we know that positive and negative numbers are both on opposite sides of zero- negatives on the left, positives on the right. We see that we have a positive and negative. That lets us know that we have these two values on opposite sides. As for one, we see that it's (going to assume it's negative, as that's what it looks like. If not, do the same thing on the other side.) 5/8, we can only do fourths here, it seems, because there are four intervals between the numbers. Here's where the beauty of equivalent fractions comes in. 5/8 actually equals 2.5/4 if you divide the top and bottom by 2. Now it should be easy to graph it. A little after 1, and then in between 2 and three. Hope this helps.

The half-life of radioactive cobalt is 5.27 years. Suppose that a nuclear accident has left the level of cobalt radiation in a c
sweet [91]

Answer:

  35 years

Step-by-step explanation:

The proportion p that remains after y years is ...

  p = (1/2)^(y/5.27)

In order for 1/100 to remain (the level decays from 100 times to 1 times), we have ...

  .01 = .5^(y/5.27)

  log(0.01) = y/5.27·log(0.5) . . . take logs

  y = 5.27·log(0.01)/log(0.5) ≈ 35.01 ≈ 35 . . . . years
