Solve the problem.A BASE jumper's velocity (in meters per second) after t seconds is given by 
where m is the mass of the object in kilograms, g = 9.8 m/s2 is the acceleration due to gravity, and k is a physical constant. How fast is the BASE jumper falling at the end of a 16 second delay? Use 
and 
Round the answer to one decimal place if necessary.
A. 959 m/s B. 59.9 m/s C. 19.8 m/s D. 61.3 m/s
To further justify the Cofunction Theorem, use your calculator to find a value for each pair of trigonometric functions below. In each case, the trigonometric functions are cofunctions of one another, and the angles are complementary angles. Round your answers to four places past the decimal point. ? sin 23°, cos 67° ?
A. sin 23° = 0.3907, cos 67° = -0.9205 B. sin 23° = -0.3907, cos 67° = 0.9205 C. sin 23° = 0.3977, cos 67° = 0.9135 D. sin 23° = 0.3907, cos 67° = 0.3907 E. sin 23° = 0.3857, cos 67° = 0.9205
Determine the equation of the given line, as well as the slope of the line. If the slope is undefined, state this.
