$(g+h)(x) = x^3+6x+3$

Step-by-step explanation:

The operations on functions can be performed as they are performed on polynomials

The addition of functions is used in the given question

Given

$g(x)=x^3+5x\\h(x)=x+3$

We have to find:

$(g+h)(x)=g(x)+h(x)\\=x^3+5x+x+3\\=x^3+6x+3$

So,

$(g+h)(x) = x^3+6x+3$

Enter the indicated element.

Ymorist [56]

$a_{1,3} = 9$

Step-by-step explanation:

The elements of matrices are represented in the form

$a_{r,c}$

Here r is the row number and c is the column number.

Given matrix is:

$A = \left[\begin{array}{ccc}3&6&9\\2&4&8\end{array}\right]$

The elements of matrix will be represented by a_{r,c}

We have to find $a_{1,3}$

Which means that the first row and third column.

The first row is: 3 6 9 and the element in third column is: 9

So,

$a_{1,3} = 9$

A right triangle has legs of lengths 6 and 15 inches. Find the length of the hypotenuse (nearest tenth).

zubka84 [21]

Answer:

The length of the hypotenuse is 16.2 inches.

Step-by-step explanation:

$c^{2} = a^{2} + b^{2}$

$c^{2} = 6^{2} + 15^{2}$

$c^{2} = 36 + 225$

$c^{2} = 261$

$\sqrt{c^{2} } = \sqrt{261}$

$c = 16.2$
