question 215

Multiple Choice

Use Mathematical Models
-The winning times (in seconds) in a speed-skating event for men can be represented by the formula $\mathrm { T } = 46.18 - 0.095 \mathrm { x }$ , where $\mathrm { x }$ represents the year, with $\mathrm { x } = 0$ corresponding to 1920 . (For example in $1992 , \mathrm { x }$ would be $1992 - 1920 = 72$ .) According to the formula, what was the winning time in 1998 ? Round to the nearest hundredth.

• A) \(38.77 \mathrm { sec }\)
• B) \(3594.63 \mathrm { sec }\)
• C) \(39.72 \mathrm { sec }\)
• D) \(40.67 \mathrm { sec }\)
