SOLVE BY SECANT METHOD Determine the root of f(x) = x³- 6x² + 11x 6.1 with initial values xo perform 3 iterations and obtain the relative percentage error in the last iteration - = 2.5 and x1 = = 3.5,

A ball is thrown directly upward from a height of 4ft with an initial velocity of 28 ft/sec. The function s(t)=-16t^2+28t+4 gives the height of the ball,in feet,t seconds after it has been thrown.Determine the time at which the ball reaches its maximum height and find the maximum height.    ^ indicates it to be squared but was not able to find this on my phone so please ensure it's squared thanks

A group of researchers found that people prefer YouTube videos that aren't too long, but not too short either. Suppose these researchers determined that the ratings people gave to a video could be approximated byR(t)=20t/t^2 + 100 where t is the length of the video in minutes and R(t) is its rating. What length of video (in minutes) will get the highest rating?
