Find y if the line through (5,3) and (-3, y) has a slope m = -
We didn't need to see all that code to know that answer.
I. Rectangle(int s1, int s2) { }
is a valid constructor
I<span>I. Rectangle(s1, s2) { }
is an invalid constructor, as the data type for s1 and s2 was not specified.
</span>II<span>I. Rectangle() { }
is a valid constructor, as it is simply the default constructor.</span>
The code of five digits is of the form:
A B C D F
Where A (the first digit) may be any of 9 digits (because 0 is excluded)
B, C, and D, may be each any of 10 digits (0 - 9)
F (the last digit) may be 0, 2, 4, 6 or 8, i.e. 5 different digits.
So the number of different available codes is:
9 * 10 * 10 * 10 * 5 = 45,000.
Answer: 45,000
Doing so would not only increase your productivity potential / but also increase your productivity STANDARDS for certain jobs (e.g. data entry; secretarial work), which is a direct skill that is valuable to employers. Furthermore, if you work in a a secretarial job, this would allow you to accomplish tasks such as "touch typing" a lot faster (without sacrificing quality) — allowing you more time to accomplish other tasks, making you more efficient and even promotable in terms of pay raise and in terms of promotable to other positions with higher earnings — and even teach new staff members.
