A four-character password to log onto a computer is drawn from the digits 0-9 and
a subset of 23 letters of the alphabet (repetition is permitted). Determine the number of passwords possible if
a) the letters used are not case sensitive (that is, a lowercase letter is treated the same as an uppercase letter).
b) the letters used are case sensitive (that is, an uppercase letter is considered different than the same lowercase letter).

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3
