Answer:
see below
Step-by-step explanation:
As you can see 5 - 3 = 2, 2 - 3 = -1 and -1 - 3 = -4 so the rule is subtract 3.
You want to know how long it'll take for the bacteria to grow
to (800/500) = 1.6 times their initial population.
The number of double-times it'll take is
[ log(1.6) / (log(2) ] = 0.6781 .
The double-time for these particular critters is 12 hours,
so it'll take them
0.6781 x 12 hours = 8.137 hours
= 8 hours 8.2 minutes .
To solve this problem you must apply the proccedure shown below:
1. Let's order the position of each runner shown in the table from greatest to least, to see which one is closer to zero:
-0.480 meters (Runner D).
= -0.56 meters (Runner E).
-1.05 meters (Runner C).
= -1.25 meters (Runner B).
-1.264 meters (Runner A).
= -1.625 meters (Runner F).
2. As you can see, the position of the runner that is closer to zero is:
-0.480 meters (Runner D)
3. Therefore the runner D finished in second place.
4. The runner B finished in fifth place.
The answer is: The runner D finished in second place and the runner B finished in fifth place.
Answer:
Step-by-step explanation:
In multiplication of fractions you can do this:
.
So that is exactly what we are going to do here:
We know that 12 divided by -6=12/-6 =-2.
We also know assuming x isn't 0 that x^a/x^a=1.
On the last fraction, the only thing you can do there to simplify is use the following law of exponents: .
So we have
Simplifying a bit and leaving out the ( ).
