Expert Solution
Step 1

(a)Initially helicopter is at the height of 200 feet

Altitude of the helicopter increases by 150 feet each minute

Let t is the number of minutes since the helicopter take off

Altitude=initial height+number of minutes after take off *rate of increase in amplitude

h=200+ t×150

Hence the height hof helicopter tminutes after its takeoff is

h=200+150t
