11) If A = {19, 20, 21, 24} and B = {17, 19, 20, 22), list the elements of A U B.

Elodia [21]

Answer:

A U B = {17, 19, 20, 21, 22, 24}

Step-by-step explanation:

The symbol U is the union symbol, which denotes the union of two sets.

This means that given two sets A and B, the expression

A U B

indicates all the elements that belong to either set A or set B.

In this problem, we have the following two sets:

A = {19, 20, 21, 24}

B = {17, 19, 20, 22}

We can therefore list all the elements belonging to either set A or set B, they are:

17, 19, 20, 21, 22, 24

So, the expression A U B indicates the set:

A U B = {17, 19, 20, 21, 22, 24}

The perimeter of a rectangular field is 264 yards. If the width of the field is 54 yards, what is its length?

SIZIF [17.4K]

P = 2(L + W)
P = 264
W = 54

264 = 2(L + 54)
264 = 2L + 108
264 - 108 = 2L
156 = 2L
156/2 = L
78 <=== Length is 78 yards

What is f(x) = 7x2 42x written in vertex form? f(x) = 7(x 6)2 – 6 f(x) = 7(x 6)2 – 42 f(x) = 7(x 3)2 – 9 f(x) = 7(x 3)2 – 63.

ioda

The vertex form of the function f(x) is $\rm f(x)= 7 ( x + 3 )^2 - 63$ .

<h2>Given </h2>

Function; $\rm f(x) = 7x^2 + 42x$

<h3>What is the vertex form of function?</h3>

The vertex of a parabola is the point at which the parabola passes through its axis of symmetry.

The standard equation which represents the vertex form of the function is;

$\rm f(x) =(x-h)^2+k^2$

Where h and k are vertexes of the given parabola.

The function is in vertex form;

$\rm f(x)= 7 x^2 + 42 x\\\\ f(x) = 7 ( x^2+ 6 x ) \\\\ f(x)= 7 ( ( x^2+ 6 x + 9 ) - 9 ) \\\\ f(x)= 7 ( x + 3 )^2 - 63$

Hence, the vertex form of the function f(x) is $\rm f(x)= 7 ( x + 3 )^2 - 63$ .
