16 because 3 divided by 8 is 0.375 and 6 divided by 0.375 is 16.
Answer:
-3
Step-by-step explanation:
The equation which models the distance (d) of the weight from its equilibrium after time (t) is equal to d = -9cos(2π/3)t.
<h3>What is the period of a cosine function?</h3>
The period of a cosine function simply means the total length (distance) of the interval of values on the x-axis over which a graph lies and it's repeated.
Since the weight attached is at its lowest point at time (t = 0), therefore, the amplitude of equation will be negative nine (-9)
For the angular velocity at time period (t = 3s), we have:
ω = 2π/T
ω = 2π/3
Mathematically, the standard equation of a cosine function is given by:
y = Acos(ω)t
Substituting the given parameters into the formula, we have;
d = -9cos(2π/3)t.

Answer:
Total sales revenue use excel function : ( SUMIF. =sumif(range, criteria, [sum_range] )
For each of the stores: Use excel function: For Store 1: =sumif(B4:B99,1,I4:I99) then repeat same for Store 2 to store 8
Step-by-step explanation:
To modify the spreadsheet to calculate the total sales revenue we will add a column " sales revenue "
multiply values of column : ( unit sold * unit price ) to get Total sales revenue. then use excel function : ( SUMIF. =sumif(range, criteria, [sum_range] ) to find Total sales revenue
calculate the total revenue for each of the 8 stores using a pivot table using "store identification number" in row and " sales revenue " in values field
To get the sales revenue ; replace " store identification value" with sales region " column
