Answer:

$y=-2\,(x-6)^2+246$

with the video game cost of x = $6

This agrees with the last option in the list of possible answers

Step-by-step explanation:

Recall that the maximum of a parabola resides at its vertex. So let's find the x and y position of that vertex, by using first the fact that the x value of the vertex of a parabola of general form:

$y=ax^2+bx+c$

is given by:

$x_{vertex}=\frac{-b}{2\,a}$

In our case, the quadratic expression that generates the parabola is:

$y=-2x^2+24x+174$

then the x-position of its vertex is:

$x_{vertex}=\frac{-b}{2\,a}\\x_{vertex}=\frac{-24}{2\,(-2)}\\x_{vertex}=\frac{-24}{-4)}\\x_{vertex}=6$

This is the price of the video game that produces the maximum profit (x = $6). Now let's find the y-position of the vertex using the actual equation for this value of x:

$y=-2x^2+24x+174\\y_{vertex}=-2\,(6)^2+24\,(6)+174\\y_{vertex}=-72+144+174\\y_{vertex}=246$

This value is the highest weekly profit (y = $246).

Now, recall that we can write the equation of the parabola in what is called "vertex form" using the actual values of the vertex position $(x_{vertex},y_{vertex})$ :

$y-y_{vertex}=a\,(x-x_{vertex})^2\\y-246=-2\,(x-6)^2\\y=-2\,(x-6)^2+246$

Therefore the answer is:

$y=-2\,(x-6)^2+246$

with the video game cost of x = $6

Answer: 29.75%

Step-by-step explanation:

X/100 *80.33=23.90

80.33x=2390

X=2390/80.33 = 29.75

If the prisms below are similar what is the ratio of the surface area of the smaller prism to the surface area of the larger pri

Ronch [10]

The ratio between the surfaces areas of the two prisms is equal to 6.25.

<h3>How to get the ratio of the surface areas?</h3>

The ratio between the volumes of the prisms is:

$R_v = \frac{375 in^3}{24 in^3} = 15.625$

This number is equal to the cube of the scale of dilation applied to the dimensions of the smaller prism, so the scale factor is:

$\sqrt[3]{15.625} = 2.5$

And the ratio between the areas should be the square of the scale factor, then we will have that the ratio between the surface areas of the two prisms is:

$2.5^2 = 6.25$

You are scheduling a new delivery route and you need to find out how long it will take a driver to complete the route. You start

Sergio039 [100]

The route will take four hours and fifteen minutes. If you start at 9:50 and count four hours, you'll get to 1:50, add ten to get to 2:00, then add 5 minutes to get to 2:05. Four hours plus ten minutes plus five minutes, 4:15.
