SOMEONE PLEASE ANSWER ASAP FOR BRAINLIEST!!!!!
kaheart [24]

Answer:

 D     b = -2E +212

Step-by-step explanation:

The slope is given by -2 for every 1000 ft

The initial value is 212 degrees

We can use

y = mx+b  where m is the slope and b is the initial value

y = -2x +212

We are at an elevation of E thousand ft

Replace x with E

y = -2 *E +212

b is the boiling point at this elevation

We  replace y with b

b = -2E +212

A user’s password to access a computer system consists of 3 letters followed by 2 digits. How many different passwords are possi
Vesnalui [34]

Answer:

26*26*26 = 17576 ways to select 3 letters

10*10= 100 ways to select 2 numbers

So then the total number of ways are:

26^3 *10^2 = 1757600 possible ways

Step-by-step explanation:

For this case we assume that we have 26 letters from A to Z and 10 numbers from 0 to 9 .

And we want to calculate the number of possible passwords possible if the password consists of 3 letters followed by 2 digits.

And for this case we can use the multiplication principle of combinatories, since we don't have any restriction about the letters of the numbers we can have repetition of letters or numbers.

For the number of possible letters:

26*26*26 = 17576 ways to select 3 letters

10*10= 100 ways to select 2 numbers

So then the total number of ways are:

26^3 *10^2 = 1757600 possible ways
