Find the derivative of the function 4x - 9 y= 9x + 1

Consider a stone tossed into the air from ground level with an initial velocity of 17 m/s. Its height in meters at time = 17t - 4.98. t seconds is h(t) Compute the average velocity (in m/s) of the stone over the given time intervals. (Round your answers to six decimal places.) [1, 1.05] [1, 1.01] [1, 1.005] [1, 1.001] Consider the average velocities above to guess the instantaneous velocity (in m/s) of the stone at t = 1 s. (Round your answer to one decimal place.) m/s
