Answer:

Step-by-step explanation:
He already has songs = 41
Since we are given that he purchase four songs every week .
So, in first week he purchase songs = 4
Initially he already has 41 songs
So, total songs after 1 week = 
After 2 weeks he will have songs = 
This forms an arithmetic sequence : 41,45,49......
Formula of nth term in A.P. : 
a = first term = 41
d = common difference = 45-41=49-45=4
Since we are required to find the new songs after110 weeks
So, n =110
Substituting values :

Thus Option A is correct.
Answer:
Ques 1 - 
Ques 2 - 
Step-by-step explanation:
Ques 1: From the table, we see the relation,
5 = 2 × 2 + 1
9 = 2 × 4 + 1
13 = 2 × 6 + 1
17 = 2 × 8 + 1
21 = 2 × 10 + 1
That is, the relation from the table is given by,
, where x is the input and y is the output.
Hence, the required equation is
.
Ques 2: From the table, we see that,
2 = 12 × 0 + 2
14 = 12 × 1 + 2
26 = 12 × 2 + 2
38 = 12 × 3 + 2
50= 12 × 4 + 2
That is, the relation from the table is given by,
, where x is the input and y is the output.
Hence, the required equation is
.
A cylinder has a cross section of a circle as well as the sphere.
Ich would das that the derivative of
f(x) = 6x+2
is 6
because of derivative 6x it is 6 and the derivative of 2 is 0
