An online shopping club has 10,000 members when it charges $7 per month for membership. For each $1 monthly

Sonja [21]

Answer:

The function that can be used in the online shopping club about its monthly revenue is:

$R = -400x^{2} +7200x+70000$

Step-by-step explanation:

First, we're gonna take into account the different values we have in the exercise:

10,000 members
$7 per month for membership
Loses of 400 members by each $1 monthly increase

How the variable $x$ represents the price increase, we can do the formula below:

$(10000 - 400x) * (7+x)$

In this formula, we represent in the first part that by each 1 in the variable $x$ , the total of members will be reduced in 400, in the second part, we mention that at the same time, the membership fee will be increased in the same value of $x$ . Now we must simplify this function:

$(10000 - 400x) * (7+x)$

We operate the values:

$70000+10000x-2800x-400x^{2}$

Solve we can:

$70000+7200x-400x^{2}$

And organize:

$-400x^{2} +7200x+70000$

At the end, how $R$ represents the monthly revenue received by the club, we use that variable for our formula:

$R=-400x^{2} +7200x+70000$

What is the area of this figure?

Vladimir79 [104]

Answer:

<em>97 square miles</em>

Step-by-step explanation:

Let us divide this figure into rectangles, each of set dimensions;

$Dimensions of Rectangle A - Height ; 2 mi, Length ; 9 mi\\Area of Rectangle A - Height * Length = 2 mi * 9 mi = 18 square miles,\\\\Dimensions of Rectangle B - Height ; 2 mi + 5 mi = 7 mi, Length ; 5 mi\\Area of Rectangle B - Height * Length = 7 mi * 5 mi = 35 square miles,\\\\Dimensions of Rectangle C - Height ; 4 mi + 5 mi + 2 mi = 11 mi, Length ; 4 mi,\\Area of Rectangle C - Height * Length = 11 mi * 4 mi = 44 square miles,\\\\Area of Figure = 18 + 35 + 44 = 97 square miles$

<em>Solution; 97 square miles</em>
