Answer:
This series is divergent
F
Step-by-step explanation:
we are given a series
Firstly, we will find nth term
Numerator:
3, 4, 5,...
so, nth term will be
Denominator:
4,5,6,....
so, nth term will be
so, we can find it's nth term as
we can use divergent test
we can divide top and bottom by n
now, we can plug n=inf
Since, it is non-zero value
so, this series is divergent

Answer:
The ladder reaches 4.8 ft up the wall
Step-by-step explanation:
Find the perpendicular line then find the intersection then find the point
perpendicular lines have slopes that are perpendicular
the slopes multiply bo -1
y=mx+b
m=slope
y=2x-3
2 is slope
2 times what=-1
what=-1/2
the equation is
y-3=-1/2(x-8) or
y=(-1/2)x+7
find intersection
