Answer:

Answer:

a.

1.56 million

Step-by-step explanation:

R(t)=0.0001(-t⁴+12t³-77t²+600t+13650)

R(5)=0.0001(-(5)⁴+12(5)³-77(5)²+600(5)+13650)

R(5)=0.0001 (-625+1500-1925+3000+13650)

R(5)=0.0001 x 15600

R(5)= 1.56

so, 1.56 million

b.

Answer:

in the 3rd year

Step-by-step explanation:

R(t)=0.0001(-t⁴+12t³-77t²+600t+13650)

R(3)=0.0001(-(3)⁴+12(3)³-77(3)²+600(3)+13650)

R(3)=0.0001 (-81+324-693+1800+13650)

R(3)=0.0001 x 15000

R(3)= 1.5

so, 1.5 million in the 3rd year
