I want it On a paper plz

1. If an arrow is shot upward on Mars with a speed of 45 meters per second, its height in meters seconds later is given by /(t) = 45t -1.86t a. If the point P(5, 178.5) lies on h(1) and @ is the point Q (7, 45/ -1.8617 ), write an equation for the slope ma of the secant line PO, the average speed of the arrow. b. Use your graphing calculator to find the slope m, of the secant line PO (correct to five decimal places) for the following valuest . 2 approaches P from the left approaches P from the right m pa 4.8 5.2 4.9 5.1 4.99 5.01 4.9999 5.0001 c. Using the tables in part (b) above, approximate the slope m, of the tangent line at P ? d. Within the context of the situation described, interpret the meaning of the slope in, at the point P(5.178.5) . Include values and units in your response. . Find the equation of the tangent line at P( 5,178.5) using the slope m, from part (c)
