Can you please help me answer this using technlogoy tool with screen shot please.

Activity 4: Application of the Derivatives as a Rate of Change 1. The position of a particle moving along a straight line is given by the function s(t) =t'-9t' +15t where s is in meters and t is in seconds. a. Use a technology tool to graph the position, the velocity and the acceleration functions on the same plane on [0, 8] x [-25, 20]. b. Use the graph to answer the questions below: When is the particle speeding up? When is it slowing down? 2. The cost in dollars of producing x toys for toddlers is C(x) - 920+ 2x - 0.02x2 + 0.00007x3 a. Use technology to calculate the average cost per toy C(x) = (*) when 100 toys are X produced. b. Use technology to plot the cost function as a function of x in the interval 0
