Would it be 3.4, 4.3, 5.2, 6.1, 7
Answer:
47.13cm
Step-by-step explanation:
2×3.142×7.5cm
I can't make out the summand in (d), and I addressed (c) in your other question.
(a)

We have for positive integers

that

. We also are aware that the series

converges, since it is a

-series with

. Since the

-series converges in absolute value, the alternating series must also converge by comparison.
- - -
(b)

By the alternating series test, this series will converge if the absolute value of the summand is increasing for some large enough

and approaches zero.
We have

for all

, and we also have that

(where we substituted

, so that

).
Therefore (b) also converges.
Thanks but this isn’t math
Answer:
The value of a=6[/tex]
Step-by-step explanation:
<u>step 1:- </u>
<u>col linearity of three points :- </u>
We know that slopes of two parallel lines are equal.If two lines having the same slope pass through a common point ,then two lines will coincide . Hence ,If A,B,C are three points in the X Y- plane, then they will lie on a line,
that is three points are col linear if and only if Slope of AB= slope of BC
<u>step 2:-</u>
Since the given three points are col-linear, we have
Slope of AB= slope of BC
given points are A(2,-2) ,B(-6,2) and C(a,-4)
<u>Step 3 :-</u>
Slope of AB= slope of BC
