y=4
Step-by-step explanation:
4y+3=19
=4y=19-3
=y=16/4=4
Answer:
- The sum of the series is given as
7/(1 + 7z)
- The series converges for (-1/7, 1/7)
Step-by-step explanation:
Given the geometric series:
7 - 14z + 28z² - 56z³ + ...
The common ratio r is given as
-14z/7 or 28z²/(-14z) or -56z³/(28z²) and so on
r = -7z
The sum of the series is given as
S = a/(1 - r)
Where a is the first term in the series.
S = 7/(1 -(-7z))
= 7/(1 + 7z)
The series converges for |-7z| < 1
That is for -1/7 < z < 1/7
There is nothing there sorry
Answer:
58
Step-by-step explanation:
Complementary angles add up to 90
Za + Zb = 90
32 + Zb = 90
By simple algebra:
Zb = 58
