Answer:

Option B

Step-by-step explanation:

Taking the derivative of the residual function, then applying the normal equation:

[a; b] = (X'*X)^(X'*y)

with

X = [1 1; 2 1; 3 1; 4 1; 5 1]

X' is transpose of X

y = [11; 8; 4; 1; 0]

[a; b] =  [-2.9 13.5]

In the recursive formula an = an−1 + 5, the value of the previous term is represented by
den301095 [7]

Step-by-step explanation:

In the recursive formula an = an−1 + 5

a_n = a_{n-1}+5

Suppose if a_5 is the nth term then previous term is a_4

To get the previous term we need to subtract 1 from the n

So a_n is the nth term

a_{n-1} is the previous term

Here 5 represents the common difference between two terms

So value of previous term is represented by

a_{n-1}

Answer : a_{n-1}

I need x and GH there is two answer to this!! Please help
g100num [7]

Answer:

<em>15</em>

Step-by-step explanation:

9x - 3 = \frac{(5x + 1) +19}{2}

2(9x - 3) = 5x + 1 + 19

18x - 6 = 5x + 20

13x = 26

x = 2

<em>GH</em> = 9(2) - 3 <em>= 15</em>
