Answer:
=
+
+ C where C is the constant of integration.
Step-by-step explanation:
i)it is given that the rate of change of W with respect to x is proportional to
x + 18. Therefore
= k(x + 18) where k is a constant.
ii) Therefore
=
+
+ C where C is the constant of integration.
iii) the complete solution can only be found if we know the constant of proportion and also the constant of integration.
We know that there are 36 number cards and 16 face cards in standard deck of 52 cards. Now choose two cards without replacement from 52 cards.
The number of ways of choosing any 2 cards without replacement from 52 cards is
.
The number of ways of choosing 2 number cards without replacement from 36 cards is
.
The required probability is

Correct choice is (A).
Answer:

Step-by-step explanation:
The given quadratic form is of the form
.
Where
.Every quadratic form of this kind can be written as

Observe that
is a symmetric matrix. So
is orthogonally diagonalizable, that is to say,
where
is an orthogonal matrix and
is a diagonal matrix.
In our case we have:

The eigenvalues of
are
.
Every symmetric matriz is orthogonally diagonalizable. Applying the process of diagonalization by an orthogonal matrix we have that:


Now, we have to do the change of variables
to obtain

Which can be written as:
