1)About how many years does it take for $300 to become $2,400 when compounded continuously at 5% per year?
2)Most dictionaries define acute angles and obtuse angles in terms of degrees. Choose the option that correctly restates these definitions in terms of radians.
A. An angle between 0 radians and π radians is called an acute angle. An angle between π radians and 2π radians is called an obtuse angle.
B. An angle between 0 radians and π/2 radians is called an acute angle. An angle between π/2 radians and π radians is called an obtuse angle.
C. An angle between 0 radians and π/4 radians is called an acute angle. An angle between π/4 radians and π/2 radians is called an obtuse angle.
D. An angle between 0 radians and π/4 radians is called an acute angle. An angle between π/4 radians and π radians is called an obtuse angle.
E. An angle between 0 radians and 90 radians is called an acute angle. An angle between 90 radians and 180 radians is called an obtuse angle.
3)Suppose π/2 < θ < π and sin θ = 3/ 8 . Evaluate cos θ in exact fraction?
