a marrow plant is 0.5 m long.Every week it grows by 20%     

a)Find the value of the common ratio.     

b)calculate how long the plant is after 12 weeks.     

C)comment on the predicted lenght of the marrow after one year.     

 

a)  Find the value of the common ratio.     

     The common ratio is 1.20     

 

b)  Calculate how long the plant is after 12 weeks.     

     (5 m) • (1.20)¹²  =  44.58 m      

 

c)  Comment on the predicted length of the marrow after one year.     

     After 52 weeks it would be (5 m) • (1.20)⁵²  =  65,523.15 m     

     At 3.2808 ft/m, that comes to more than 214,968 feet long.
