For a science experiment, a projectile was launched. Its path was given by h(d) = -4.9d + 65d + 10, where h(d) is the height of the projectile above the ground and d is the horizontal distance of the projectile from the launch pad, both in metres. What was the maximum height of the projectile, to the nearest tenthof a metre?
