Answer:
Take the starting point as the first natural number that is 1.
Step-by-step explanation:
To find: a starting point so that the first 5 numbers in the sequence are all positive
Solution:
Natural numbers are numbers that are used for counting.
Natural numbers are basically positive integers.
Take the starting point as the first natural number that is 1.
The next point as 2.
The next point as 3.
The next point as 4.
The next point as 5.
So, the sequence becomes so that the first 5 numbers in the sequence are positive.
Answer:
Option (3)
Step-by-step explanation:
By applying cosine rule in the triangle ABC,
BC² = AC² + AB² - 2(AC)(AB)cosA
5² = 3² + 7²- 2(3)(7)cosA
25 = 9 + 49 - 42cos(A)
25 = 58 - 42cos(A)
cos(A) =
A =
A = 38.21°
A ≈ 38°
Option (3) will be the correct option.
