Q1/ Determine the real roots of f(x) = -0.6x² +2.4x + 5.5 by using the bisection method to determine the highest root with E<0.001. Employ initial guesses of xi = 5 and x₂ = 10. (Carry out 4 decimal places in your work)?

P(c < or equal to Z < or equal to -.65) = .2395   Please help me solve this as clearly as possible.  I want to understand.

The deck of a bridge is suspended 285 feet above a river. If a pebble falls off the side of the bridge, the height, in feet, of the pebble above the water surface after t seconds is given by  y = 285 − 16t2. (a) Find the average velocity (in ft/s) of the pebble for the time period beginning when t = 2 and lasting the following amount of time. (i) 0.1 seconds  (ii)0.05 seconds  (iii)0.01 seconds  (b) Estimate the instantaneous velocity (in ft/s) of the pebble after 2 seconds.
