According to the credit card numbering scheme, 5038120045630085 is a valid credit card number. suppose someone input the number as 5018320045630085, would the error be detected?
a) yes, according to this error-detection system, the result of the scheme of the incorrect number would not be divisible by 10.
b) no, the error is that the third and fifth numbers were switched and since both numbers are in odd-numbered positions, the total would still be divisible by 10.
c) yes, this error-detection system will detect all transposition errors.
(ii)
find the check digit * that should be appended to the upc code 0-21243-20381-*.
a) 0
b) 2
c) 4
(iii)
which of the following statement is not true?
a) a bar code is a series of dark bars and light spaces that represent characters.
b) any system for representing data with only two symbols is a binary code.
c) a zip + 4 code can be represented by 45 bars with five bars for each digit.

step-by-step explanation:

add 6% to the value she got from selling the house.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
