3x + 7(3x+4)

Distribute:

=3x + (7)(3x) + (7)(4)

=3x + 21x + 28

Combine like terms:

=3X + 21X +28

=(3x + 21x) + (28)

=24x +28

For any two documents x and z, define k(x; z) to equal the number of unique words that occur in both x and z (i.e., the size of
liq [111]

Answer:

Yes, the function is a kernel

Step-by-step explanation:

Given

Document x an z

Function definition! k(x:z)

We want to show that the above is a kernel.

To do this, we'll explicitly construct feature vectors φ(x) and φ(z)

This gives;

K(x,z) =φ(x)·φ(z).

Given than any document; say x and z

A vocabulary V can be constructed.

Vocabulary V must have a finite size of words in the document set..

The feature mapping is constructed as φ(x) for x by the following:

For the kth word wk in V, if wk appears in document x, assign φ(x) k(the kth element ofφ(x)) to be 1; else φ(x)k to 0.

Then the number of unique words common in x and z is φ(x)·φ(z), giving us the kernel

Given the following sequence, find the 14th term: 3, 1, –1, –3, –5, . . .
AVprozaik [17]
3, 1, -1, -3, -5
 -2  -2  -2  -2

a(n) = a₁ + d(n - 1)
a(n) = 3 - 2(n - 1)
a(n) = 3 - 2(n) + 2(1)
a(n) = 3 - 2n + 2
a(n) = -2n + 3 + 2
a(n) = -2n + 5
   a₁₄ = -2(14) + 5
   a₁₄ = -28 + 5
   a₁₄ = -23

The answer is C.
