In the dental industry, light-activated adhesives have been used for decades to help adhere braces to teeth as well as being used in other dental procedures. These adhesives are one-part translucent polymers that cure and harden when exposed to specific light spectrum. Many of these took up to 30 seconds to cure. New technology brings LED blue light curing which uses blue LED with UV light to cure and harden a light-activated adhesive in 3-5 seconds. Which result below would NOT be an advantage of this new technology?<u> A)There is a higher up-front expense.</u> B)Could be used in other areas such as sealing cracked pipes. C)No filters or cooling fan required due to quick curing and low heat emission. D)There is a major time savings when using the faster high–intensity curing lights.
The answer is D. The SUM function lets you add all the values along the specified cells. To use the SUM function, you type the equal symbol and the word "sum" then a parenthesis. Inside the parenthesis are the cells you want to add-up. Specify it from the first cell to the last. Add a colon in between to two cell locations. So the right formula to input in finding the sum of all the values from A1 to A10 is =sum(A1:A10).
