Use a Calculator to Find the Function Value $\mathrm { F }$

question 133

Multiple Choice

Use a calculator to find the function value. Give your answer rounded to seven decimal places, if necessary.
-The grade resistance $\mathrm { F }$ of a car traveling up or down a hill is modeled by the equation $\mathrm { F } = \mathrm { W } \sin \theta$ , where $W$ is the weight of the car and $\theta$ is the angle of the hill's grade $( \theta > 0$ for uphill travel, $\theta < 0$ for downhill travel) . Find the weight of the car (to the nearest pound) that is traveling on a $- 2.6 ^ { \circ }$ downhill grade and which has a grade resistance of $- 140.63 \mathrm { lb }$ .

• A) \(2900 \mathrm { lb }\)
• B) \(3200 \mathrm { lb }\)
• C) \(3100 \mathrm { lb }\)
• D) \(3400 \mathrm { lb }\)
