Answer:
- geometric
- arithmetic
- neither (Fibonacci sequence)
Step-by-step explanation:
If ratios are the same, it is geometric:
8/4 = 16/8 = ... = 2
If differences are the same, it is arithmetic:
-4-(-8) = 0 -(-4) = ... = 4
If neither is the case, it is neither:
3-2 ≠ 5 -3
3/2 ≠ 5/3
In this last sequence we see that differences equal the previous term. This is characteristic of the Fibonacci sequence, which sees wide use in Nature, and has a relationship to the Golden Ratio. (The ratios of successive terms approach the golden ratio (1+√5)/2 ≈ 1.618.)
Answer:
40.3 cubic foot
Step-by-step explanation:
Perimeter of the pyramid's base=11.1 ft
Now, this is a square base, and we know that:
Perimeter of a Square=4l
Therefore: 4l=11.1
l=11.1/4=2.775 ft
- The length of a side of the base =2.775 ft
- Height of the Pyramid =15.7 ft
Volume of a pyramid
Answer:
60°
Step-by-step explanation:
As we can see it is an equilateral triangle so all angles are equal so
x = 60°
Hope it will help :)
(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.
