Q. Find the second derivative of the function.f(x)=−sin(x)f′′(x)=______
Identify Total Tape Amount: Step 1: Identify the total amount of tape needed and the amount per roll.Total tape needed = 8,000cm, Tape per roll = 2,000cm.We need to divide the total amount by the amount per roll to find the number of rolls.Calculation: 8,000cm÷2,000cm.
Calculate Number of Rolls: Step 2: Perform the division to determine the number of rolls. 8,000÷2,000=4. This means the electrician needs 4 rolls of tape.
