The revision cloud is used to provide a notification indicating that changes will be made to a drawing in the future.

In the field of technical drawing and drafting, a revision cloud is a graphical symbol or annotation used to highlight areas of a drawing that will be modified or revised at a later stage. It is typically represented as a freehand sketch in the shape of a cloud, enclosing the specific area or section that requires revision.

The revision cloud serves as a visual indicator to inform viewers that changes are planned for that particular part of the drawing. It helps to draw attention to the portions that need revision, ensuring that stakeholders and other individuals involved in the project are aware of the intended modifications.

By using revision clouds, it becomes easier to communicate and track changes throughout the drafting process, facilitating effective collaboration and ensuring that everyone is on the same page regarding the upcoming alterations.

Given a recursive function public int recur(int x) {if(x > 10) return 2*recur(x/2);if(x < 10) return recur(x + 2) / 2;return 10;} The output of the function recur(12) is 2.

To compute recur(12), we will begin with the first conditional statement x > 10 since 12 > 10, therefore the value of recur(6) is computed using the first conditional statement where the argument for the next recursive call is half the current value of x; that is recur(6)=2*recur(3).The next recursive call is recur(3) because the previous call gave recur(3). Since 3 < 10, we use the second conditional statement which gives recur(5).Again we use the second conditional statement to compute recur(7) which gives recur(6) because 7+2=9 and 9 is less than 10.Using the first conditional statement, we compute recur(3) which gives recur(1) because 3/2=1Using the second conditional statement again, recur(3) gives recur(5)Now we use the second conditional statement again to compute recur(7) which gives recur(6).Again, we use the first conditional statement to compute recur(3) which gives recur(1).Again, we use the second conditional statement to compute recur(3) which gives recur(5).Finally, we use the second conditional statement again to compute recur(7) which gives recur(6) because 7+2=9 and 9 is less than 10. recur(6)=2*recur(3)=2*recur(1)=2*1=2

As a best practice, you should only use the height and width attributes of an img element to specify the dimensions of the image. T/F

When it comes to specifying the dimensions of an image using the height and width attributes of an `<img>` element, it is generally considered a best practice. By providing explicit values for the height and width, you can ensure that the space required for the image is reserved in the layout of the web page, preventing content reflow when the image loads.

Using the height and width attributes allows the browser to allocate the necessary space for the image before it is fully loaded, resulting in a smoother user experience.

It also helps with accessibility since screen readers can provide accurate information about the image's size to visually impaired users.

AI is not embraced in every industry because of the type of industry and what it requires. In some situations, a human is needed since an AI cannot determine what to do and can sometimes even cause death.

AI isn't embraced everywhere because for some things we need a person, lets say for example, we need an AI to respond to 911 calls, that simply won't work due to the many situations and training the bot too will be a nightmare. For example, if a caller says a word that normal humans can understand, or a "code word" that every human knows but they haven't bothered to tell the bot, that will be the end of the line for them.

There are mutliple reasons to not use AI depending on the situation whether its life and death or just plain impractical.
