Try Desmond scientific calculator it helps me out a lot
Answer:
- 3, 16, - 22, 54
Step-by-step explanation:
Using the recursive formula with a₁ = - 3, then
a₂ = - 2a₁ + 10 = - 2(- 3) + 10 = 6 + 10 = 16
a₃ = - 2a₂ + 10 = - 2(16) + 10 = - 32 + 10 = - 22
a₄ = - 2a₃ + 10 = - 2(- 22) + 10 = 44 + 10 = 54
Thus
the first 4 terms of the sequence are
- 3, 16, - 22, 54
This is actually an easy one.
4 day= 24 hours X 4 = 96 hrs.
4560 = 96 hrs.
4560/96 = per hr.
47.5 watts per hr.
Since 1 day = 24 hrs, 47.5 X 24 = 1140 Watts per day.
See? Simple and easy if you solve parts at a time!
