Lady_Fox [76]

The question is an illustration of combination and there are 729 potential pass codes available

<h3>How to determine the number of potential pass codes?</h3>

The given parameters are

Symbols available = 9

Length of pass code = 3

From the question, we understand that a symbol may be entered any number of times.

This means that each of the 9 available symbols can be used three times

So, the number of potential pass codes is

Passcodes = 9 * 9 * 9

Evaluate the product

Passcodes = 729

Hence, there are 729 potential pass codes available

8_murik_8 [283]

Answer:

We are given

Scientist begins with 150 milligrams of a radioactive substance

so,

we can use formula

we can plug Po=150

After 29 hours, 75 mg of the substance remains

so, at t=29 , P=75

we can plug it

now, we can solve for k

now, we can take ln on both sides

now, we can plug it back

and we get

we can plug t=33

we get
