The time that will be used to perform a multiplication using the approach is 28 time units.

<h3>How to calculate time taken?</h3>

From the information given, the following can be noted:

A = 8 (bits wide)

B = 4 time units.

The multiplication will be performed based on the adder stack. Since A = 8, then, A - 1 = 8 - 1 = 7.

Now, the time taken will be:

= 7 × B

= 7 × 4tu

= 28 tu

In conclusion, the correct option is 28 time units.

In spreadsheet programs, labels and constant values are always copied exactly to the new location; what happens to formulas when
Dima020 [189]

Answer:

absolute cell referencing

Explanation:

Excel has an A1 reference style, which means that the columns are called letters A to XFD and the rows have numbers, 1 to 1,048,576. The total number of columns in Excel 2007 is 16384.

A cell can contain a value, formula or constants. A formula begins with a sign = (equal). You can use values ​​from other cells in your formula. To use another value, create a reference to the cell that contains the value you want to use in your formula.

When you copy a cell that contains a relative reference and paste it into another cell, the relative reference changes

When you copy a formula that contains relative references, the reference changes when you paste it into another cell.

How much the reference changes in relation to the position of the copied cell and the position of the new cell in which the formula is pasted. Excel uses relative references by default.

Instead, an absolute reference in a formula remains the same if it is copied to another cell.

Suppose you will invest $100 per month at the beginning of the month for 40 years with interest rate
Alexeev081 [22]

Answer:

future value = 232369.1361

return % = 384.10 %

Explanation:

given data

principal = $100 per month

time = 40 year = 480 months

rate = 6.25 % yearly = 0.0625 yearly = 0.005208 monthly

to find out

total amount of capital at the end of your investment and percentage is  your total return

solution

so here future value formula is

future value = P \frac{(1+r)^{t-1}}{r} * (1+r)   ..........1

here r is rate and t is time and P is principal

so put all value

future value = 100 \frac{(1+0.005208)^{480-1}}{0.005208} * (1+0.005208)

future value = 232369.1361

so

Total capital at the end of investment-Total principle invested over the years

232369.1361 - 100 ( 12 × 40 )

184369.1361

so

Return % = \frac{184369.1361}{48000} × 100

return % = 384.10 %
