Answer:
an=9+(n−1)3, an=3n+6
Step-by-step explanation:
Arithmetic Sequence:
d=3
This is the formula of an arithmetic sequence.
an=a1+d(n−1)
Step 1: Substitute in the values of
a1=9 and d=3.
an=9+(3)(n−1)
Step 2: Simplify each term.
an=9+3n−3
Step 3: Subtract 3 from 9.
an=3n+6
Answer:
<em>8.3 mm</em>
Step-by-step explanation:
An enneagon is a polygon with 9 sides, also called nonagon.
In a regular polygon, all sides are congruent, so the length of any side is the perimeter divided by the number of sides.
length of a side = perimeter/number of sides
length of a side = 74.7 mm/9 = 8.3 mm
Finding the slope and adding up values gives an answer of 45.
Answer-
1. 3(2) + 5=6+5 = 11
2. 4(3) - 7 =12-7= 5
3. 2(3) - 4 =6-4 = 2
4. 6(4) - 2(3) =24-6 = 18
5. 2+3-4+5 = 5-4+5= 1+5 = 6
6. 7(4) - 2(2) = 28-4= 24
7. 2(3)(4) + 1 = 24+1 = 25
8. 2(3)(4) - 4 = 24-4 = 20
9. 8(2) /4 = 16/4 = 4
10. 6(3)/2 =18/2 = 9
11. 4(2) + 7 = 8+7 = 15
12. 2(4) - 7 = 8-7 = 1
13. 2(3) + 3(2) = 6+6 = 12
14. 6(2) - 1 = 12-1 = 11
15. 3(4) - 2 = 12-2 = 10
