If log 6=a, then log 600= ?

tekilochka [14]

$\log 600 = \log (100 \cdot 6)= \log 100 + \log 6 = \log 10^2 + \log 6 = \\ 2 \log 10 +\log 6 =2+\log 6 = \boxed{a+2} \\ \hbox{From formulas:} \\ \log a + \log b = \log (ab) \\ \log a^b = b\log a$

A computer can sort x objects in t seconds, as modeled by the function below: t=0.007x^2+0.003x. How long, in seconds, will it t

AlekseyPX

X objects in t seconds.....how long to sort 15 objects....so x = 15

t = 0.007(15^2) + 0.003(15)
t = 0.007(225) + 0.045
t = 1.575 + 0.045
t = 1.62 seconds <===

You have been assigned a 9 digit identification number.

aniked [119]

Answer:

1,000,000,000 identification numbers are possible.

Step-by-step explanation:

We are assigned a 9 digit identification number.

Each digit is a number from 0 to 9. So, each digit has 10 different choices.

Using the Fundamental Counting Principle (is better than the tree diagram) because it's simpler. To illustrate this, we can attempt to draw a tree diagram.

The first column will be the digits 0 to 9.

Then for each of those digits, we need another 0 to 9.

As you can imagine, the amount of numbers grow exponentially, so using the Fundamental Counting Principle is simpler.

And since we have a 9 digit identification number, with each digit having 10 choices, the total number of identification numbers possible are:

$10\times 10\times 10 \times 10\times 10 \times 10 \times 10 \times 10 \time 10\times 10=10^9=100000000$

So, 1,000,000,000 identification numbers are possible.
