Step-by-step explanation:
For a geometric sequence,
1. The sequence is :
3, 13, 23, 33,...
It is not geometric. It is false
2. The sequence is :
5, -25, 125, -625
So, the sequence is geometric as the common ratio is same. It is true.
Answer:
20 units
Step-by-step explanation:
The polygon has 4 vertices as indicated by the 4 coordinate points given.
(3, 1) and (8, 1) is a horizontal side of length 8 - 3 = 5
Similarly
(3, 6) and (8, 6) is the opposite horizontal side of length 8 - 3 = 5
Points (3, 1) and (3, 6) is a vertical side of length 6 - 1 = 5
(8, 1) and (8, 6) is the opposite side of length 6 - 1 = 5
The polygon is therefore a square of side 5 units.
Perimeter = 4 × 5 = 20 units
Answer:
Decimal Fraction Percentage
2.2 11/5 220%
2 10/5 200%
1.8 9/5 180%
1.6 8/5 160%Step-by-step explanation:
so it would be 9/5 ! since 1.8 is 9/5 .
Hope this help. Have a great day ! :)))
The vertex ok this is they answer
