The general formula for the multiplier is obtained by taking the reciprocal of the distance between adjacent tick marks on the slide rule, multiplied by the number of scale divisions that are contained within the distance between the C and D scales. The distance between the tick marks on the slide rule is usually equal to one inch or 2.54 centimeters. The distance between the C and D scales on a slide rule is usually equal to 10 inches or 25.4 centimeters. Therefore, the multiplier can be calculated as:
1 / (distance between tick marks) x (number of scale divisions between C and D scales)
1 / (1 inch) x (10 scale divisions) = 10
Converting 10 to scientific notation gives us 1.0 x 10^1.
The correct choice is C because it represents this scientific notation in hexadecimal format, which is the format commonly used for slide rule multipliers.
