First, we are going to find the vertex of our quadratic. Remember that to find the vertex $(h,k)$ of a quadratic equation of the form $y=a x^{2} +bx+c$ , we use the vertex formula $h= \frac{-b}{2a}$ , and then, we evaluate our equation at $h$ to find $k$ .

We now from our quadratic that $a=2$ and $b=-32$ , so lets use our formula:
$h= \frac{-b}{2a}$
$h= \frac{-(-32)}{2(2)}$
$h= \frac{32}{4}$
$h=8$
Now we can evaluate our quadratic at 8 to find $k$ :
$k=2(8)^2-32(8)+56$
$k=2(64)-256+56$
$k=128-200$
$k=-72$
So the vertex of our function is (8,-72)

Next, we are going to use the vertex to rewrite our quadratic equation:
$y=a(x-h)^2+k$
$y=2(x-8)^2+(-72)$
$y=2(x-8)^2-72$
The x-coordinate of the minimum will be the x-coordinate of the vertex; in other words: 8.

We can conclude that:
The rewritten equation is $y=2(x-8)^2-72$
The x-coordinate of the minimum is 8

The Carter Motor Company claims that its new sedan, the Libra, will average better than 31 miles per gallon in the city. Assumin

Nutka1998 [239]

Answer:

The null hypothesis $H_o : \mu = 31$

The alternative hypothesis $H_a : \mu > 31$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 31 \ miles / gallon$

Generally

The null hypothesis is that the company's new sedan, the Libra, will have an average of $\mu = 31 \ miles / gallon$

This mathematically represented as

The null hypothesis $H_o : \mu = 31$

The alternative hypothesis is that the company's new sedan, the Libra, will have an average better than $\mu = 31 \ miles / gallon$

This mathematically represented as

The alternative hypothesis $H_a : \mu > 31$

MrRissso [65]

Answer:

$f(x) = \frac{1}{x}$

Step-by-step explanation:

$h(x) = f(g(x)) \\ \frac{1}{x - 8} = f(x - 8) \\ f(x) = \frac{1}{x }$

The way to write this expression in mathematics is A'∩B

<h3>How to solve for the expression</h3>

In order to get the right way to write this expression we have to break it down in two parts.

First we are told that some of the elements are not in A.

This is represented as A'.

Then we are told that they are in the set B. Hence we have it written as B.

Then the expression not in set A but are in set B would be written as

A'∩B.
