Answer:
100
Step-by-step explanation:
f(n+1)=-10 f(n)
f(1)=1
put n=1
f(2)=-10f(1)=-10×1=-10
put n=2
f(3)=-10f(2)=-10×-10=100
(1)1.3t^3 +t^2 -42t +8
(2)1.3t^3 + t^2 -6t +8
(3)1.9 t^3.+ 8.4^t^2 -42t
(4)1.9t^2 -42t + 8
I hope I got that right!!
okay, now they are all separated in columns, add the ones with the same powers (e.g (1)_ 1.3t^3 + (2) 1.3t^3 + (3) 1.9 t^3 = 4.5t^3.
