Write a program that asks a user for the coefficients and and outputs the roots of that equation. be aware of the following: • be sure that your request for input and your output both have descriptive text. • if the roots have an imaginary component, use when representing the imaginary term in the output. for example, you may output "3 + " as a root. • be sure to handle the cases in which any or all coefficients are equal to zero. o if a ! = 0, there could be 2 real distinct roots, 2 real identical roots (one root of multiplicity 2), or complex roots. o if a = 0, we are left with + = 0, a linear equation with one root. o if a = b = 0, we are left with c = 0, so if user entered a non-zero value of c, write a message to the screen indicating this error.

Show that there is a language a ⚆ {0, 1} â— with the following properties: 1. for all x â a, |x| ≤ 5. 2. no dfa with fewer than 9 states recognizes a. hint: you don’t have to define a explicitly; just show that it has to exist. count the number of languages satisfying (1) and the number of dfas satisfying (2), and argue that there aren’t enough dfas to recognize all those languages. to count the number of languages satisfying (1), think about writing down all the strings of length at most 5, and then to define such a language, you have to make a binary decision for each string about whether to include it in the language or not. how many ways are there to make these choices? to count the number of dfas satisfying (2), consider that a dfa behaves identically even if you rename all the states, so you can assume without loss of generality that any dfa with k states has the state set {q1, q2, . . , qk}. now think about how to count how many ways there are to choose the other four parts of the dfa.

What is the first step in creating a maintenance ?

The camera still is bad even with the new iphone xr and especially in low light it is even worst because you can see the pixels more if its in low light. if all you apple customers want apple to fix this then lets fill there feedback with complaints about the
