0.025, 0.052, 0.205, 0.25 I believe. It's been awhile since I've been in Middle School, though. :(
1 yd 2 ft
* 8
----------------
8 yd 16 ft
but we can reduce 16 ft
there are 3 ft in a yd
16/3 = 5 yds with 1 left over
8 yds 16 ft = 8 yds + 5yds 1 ft
13 yds 1 ft

Answer:
73384 kilotons
Step-by-step explanation:
=> Total amount the 1st year = 90,000
=> Since after the 1st yr, there was a reduction of 4%, so 100% - 4% = 96% or 0.96
=> Total time = 6
We know that the formula of a geometric sequence is;
aₙ = a₁ * r⁽ⁿ⁻¹⁾
In which;
- aₙ = the value that has to be figured out (in this case it would be a₆)
- a₁ = the first term of the sequence (in this case it would be 90,000)
- r = common ration (in this case it would be 0.96)
- n = given time (in this case it would be 6)
Therefore we can finally say;
=> aₙ = a₁ * r⁽ⁿ⁻¹⁾
=> a₆ = 90,000 * 0.96⁶⁻¹
=> a₆ = 90,000 * 0.96⁵
=> a₆ = 73383.54
=> a₆ = 73384 (Rounded to the nearest whole number)
Therefore, rounding the answer to the nearest whole number, the answer would be; 73384 kilotons
Hope this helps! (Btw big shout out to jcherry99 for helping me figure this out!!)
Complex roots occur when b^2 - 4ac is negative.
So we have (-6)^2 - 4.1.k < 0
-4k < - 36
k > 9
