I don't really know the perfect answer to this but I would say because of todays technonlogy
the first row of the table is know as the table header.
=A2*D2
The above formula will allow calculation of monthly cost of the first raw material.This is done by Multiplying the contents of cell A2 (Column A, Row 2) and cell D2 (Column D, Row 2). Here Cell A2 contains cost of the first raw material and Cell D2 contains number of units of the raw material produced each month. After finding the monthly cost of the first raw material in this way, the monthly cost of other raw materials can simply be calculated by dragging down the formula to apply to the rows below.
What is that I never heard of that before
Answer:
I would reset the Domain Name System (DNS)
Explanation:
One factor that could lead to the "Site Cannot Be Reached" error is DNS "poisoning". Another is invalid DNS cache. Both can be caused by an attack on the system by people trying to spoof the system. Spoofing ensures that even when the right address is entered, it leads one to another web address.
One way to quickly reset the DNS is to run ipconfig /flushdns
This helps to clear the DNS cache.
Once the DNS cache has been successfully flushed, the system returns a confirmatory message that reads “flushed the DNS resolver cache”.
The systems administrator can now proceed to reconfigure the IP address(es)
