A sequence starts:
1 answer:
Answer:
see explanation
Step-by-step explanation:
Given the sequence
1, 4, 9, 16, ....
has n th term
= n²
(a)
Given the sequence 2, 5, 10, 17, ......
Note the terms are 1 more than the previous given sequence, thus
= n² + 1
(b)
Given 2, 8, 18, 32, ......
Note the terms are twice the original given sequence, thus
= 2n²

The difference between the length of arc BD and CE is 1.57 units
<h3>Length of an arc</h3>length of arc = ∅ / 360 × 2πr
where
- r = radius
- ∅ = central angle
Therefore,
BD = 45 / 360 × 2 × 3.14 × 6 = 1695.6 / 360 = 4.71 units
CE = 45 / 360 × 2 × 3.14 × 8 = 2260.8 / 360 = 6.28 units
Therefore, the difference between the length of arc BD and CE is as follows:
6.28 - 4.71 = 1.57 units
