The Path of a Projectile Is Modeled by the Parametric $x = \left( 85 \cos 60 ^ { \circ } \right) t \text { and }$

question 91

Multiple Choice

The path of a projectile is modeled by the parametric equations $x = \left( 85 \cos 60 ^ { \circ } \right) t \text { and }$ $y = \left( 85 \sin 60 ^ { \circ } \right) t - 16 t ^ { 2 }$ where $x$ and $y$ are measured in feet. Use a graphing utility to approximate the range of the projectile. Round your answer to two decimal places.

• A) \(312.85 \mathrm { ft }\)
• B) \(521.42 \mathrm { ft }\)
• C) \(131.09 \mathrm { ft }\)
• D) \(391.06 \mathrm { ft }\)
• E) \(195.53 \mathrm { ft }\)
