What is an easy and accurate way that a graphic designer can increase the size of a digital shape while keeping the ratio of height to width the same?
First make the height taller, and then drag the width by using one's eyes to try to make sure the proportions stay
the same
Hold the key, such as Shift, that the program uses to make sure all dimensions are adjusted while dragging just
one side
Open the shape's properties window, and type the height value multiplied by 2 and the width value multiplied by 3.
First convert the shape into a photo file, and then digitally manipulate it in a program such as Adobe Photoshop.

Write a new lc-3 trap subroutine (i.e. a subroutine that will be invoked via the trap instruction) that will receive a numeric digit entered at the keyboard (i.e. an ascii character), echo it to the screen, and return in r0 the corresponding numeric value: so if the user types the digit '7', the character '7' will appear on the screen, but the value returned in r0 will be b0000 0000 0000 0111 (#7) you may not use any trap calls in your code - you must implement the "polling" code that interrogates the keyboard status and data registers. ; getnum_tsr ; a subroutine for obtaining a numeric value ; given ascii numeric digit input to keyboard. ; the numeric digit is echoed to the console (e.g. '7' = b0000 0000 0011 0111), ; but the value returned in r0 is the actual numeric value ; corresponding to the digit (e.g. b0000 0000 0000 0111 =
