Let f (x) = 17(18 x5 - 8 x2 + 23) 3 Find the derivative of the function with respect to x. f' ( 2 ) = ?A particle oscillates so that its postion varies according to the function .5 (t) = 1.9 3 cos (2.3 t + %) where s (t) is in centimeters and t is in seconds. Find the particles velocity and acceleration after 4 seconds. Round your answers to three decimal places and write out units using / to represent per. The particles velocity after 4 seconds is Number Units The particles acceleration after 4 seconds is Number Units The mass of a tree is given by m (t) = 2.8 t 111(23 t2 + l) + 6. t 2 0, where t is the number of years after the tree was planted and m (t) is the mass in kilograms. How fast is the mass of the tree changing in 7 years. Round your answer to two decimal places and write 0ut units using / to represent per. The mass of the tree is changing by Number Units in 7 years
