Acomputer system uses passwords that contain exactly eight characters, and each character is one of 26 lowercase letters (a-z) or 26 uppercase letters (a-z) or 10 integers (0-9). let x denote the set of all possible passwords, and let a and b denote the events that consist of passwords with only letters or only integers, respectively. suppose that all passwords in x are equally likely. determine the probability of each of the following: (a) a(b) b(c) a password contains at least 1 integer.(d) a password contains exactly 2 integers.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

d? maybe

step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
