The horizontal distance or range (R) of an object thrown at an angle 0 from the horizontal is represented by the equation below where vo is the initial velocity as the object leaves the hand, in feet per second. If vo = 2500 feet per second and 0 is changed from 13° to 14°, use differentials to approximate the change in range, in feet. R= -sin20 32 A) 351091 B 521782 c) 6128 D 8609

The amount of time it takes to drive somewhere is inversely proportional to the speed at which you drive. The time of a trip is 3 hours when you drive at 60 km/h. a) Determine the equation for the function t(v), which relating the time of the trip ("t", in hours) to the speed (v, in km/h). b) Find the time it would take to complete the above trip if you drove at 90 km/h. c) What speed should you drive at to complete the trip in 75 minutes? 2.

Solve the following problems. A windmill blade with a diameter of 70 feet completes 6 rotations per minute. Calculate the linear speed (in 1. feet per minute) of the windmill blade.

QUES A ceiling fan is rotating at 30 revolutions per minute. The length of each fan blade is 3 feet long. Find the linear speed in feet per second. Report below the answer rounded to three decimal places. Your attached work must show your process to obtaining that value. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
