Isocoleese means that 2 sides and hence 2 angles are same measure
acute means that all 3 angles are less than 90 degrees
We can rule out choice I since acut means less than 90
II is a possibility, but it doesn't best describe it
III. that is true, but it doesn't include the isocileese part
IV. that is true, but doesn't include the acute part
not sure, either III or IV
this one would also be the third option
Answer:
(a) A sequence is an ordered list of numbers whereas a series is the sum of a list of numbers.
(b) A series is convergent if the sequence of partial sums is a convergent sequence, that is tends to a limit.
A series is divergent if it is not convergent.
Step-by-step explanation:
(b) An example of a divergent series is the arithmetic series 2+ 4+6+8+10+...
The sum keeps increasing without bounds.
An example of a convergent series is 100 + 50, +25 + 12.5 +... a geometric series with common ratio 0.5 whose sum tends to a limit. The limit of this series is a1 / (1 - r) = 100 / (1 - 0.5) = 200.
