Find a5, when a1 =4, r=5

Mathematics
1 answer:
sasho [114]3 years ago
3 0

Answer:

Answer: a5 = 2500

Step-by-step explanation:

For a geometric sequence:  

First term = a0  

Second term = a1 = a0*r  

Third term = a2 = a0*r^2  

Fourth term = a3 = a0*r^3  

....  

nth term = a(n-1) = a0*r^(n-1)  

Given: a1 = 4 = a0*r  

Also: r = 5  

So, a0*5 = 4 => a0 = (4/5)  

a5 = a(6-1) = Sixth term = a0*r^5 = (4/5)*5^5 = 2500  


Hope this helps

correct me if im wrong☺

What is cos(npi/2) and sin(npi/2) in fourier series cos(npi) is (-1)^n and sin(npi)=0 ?
Nat2105 [25]
The problem ask to fourier series of the trigonometric function base on the data you have been given in the problem, so the answer would be cos(pi/2n) = {(-1)^n/2 - if n is even, 0 - if n is odd} and sin(pi/2n) = {0- if n is even, (-1)^(n-1)/2 if n is odd}. I hope you are satisfied with my answer

\\\\\huge\underline\mathbb\pink{ANSWER:}\\\\

No they are not unequal... i. e. the two wires A and B are equal .

\frac{1}{3} of A = \frac{1}{3} of B

=> \frac{3}{3} × A = B

=> 1 × A = B

=> A = B

<em>:</em><em>.</em> The length of A = the length of B .
