CAN SOMEBODY HELP WITH THIS QUESTION A computer password consists of any four digits with repetition permitted.
If the letters are not case sensitive (a and A are the same), there are (BLANK)
possible passwords.
If the letter are case sensitive (a and A are not the same), there are (BLANK)
possible passwords.

IM NOT SURE

Step-by-step explanation:

im not sure, but if the passwords are only letters, here is my reasoning:

26 letters in the alphabet

26 x 26 divided by 4 = 169 (lol) - not case sensitive

26 x 26 x 26  divided by 4= 4,394 - case sensitive

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
