Area of rectangle is $2x^2+x-45$

Step-by-step explanation:

Given:

Length of rectangle = 2x-9

Width of rectangle = x+5

Required:

Area of rectangle

Formula:

$Area\,\,of\,\,rectangle=Length*Width$

Putting values of length and width:

$Area\,\,of\,\,rectangle=Length*Width\\Area\,\,of\,\,rectangle=(2x-9)(x+5)\\Area\,\,of\,\,rectangle=2x(x+5)-9(x+5)\\Area\,\,of\,\,rectangle=2x^2+10x-9x-45\\Area\,\,of\,\,rectangle=2x^2+x-45$

So, Area of rectangle is $2x^2+x-45$

To the nearest dollar, what does the analyst believe

ruslelena [56]

The analyst believes the value of the stock at the end of three weeks will be $134.

<h3>What are stocks?</h3>

Stock (also known as capital stock) in finance refers to the shares of ownership in a corporation or company.
A single share of stock represents fractional ownership of the corporation based on the total number of shares.
This typically entitles the shareholder (stockholder) to that fraction of the company's earnings, proceeds from asset liquidation (after discharge of all senior claims such as secured and unsecured debt), or voting power, which are often divided in proportion to the amount of money invested by each stockholder.

To find the value of the stock:

Because the stock price drops by 28% every week, it will be:
100 - 28 = 72% every week.
So, r = 0.72.
Then, the equation V = 360(r)∧t will be V = 360(0.72)∧t .
After 3 weeks, V = 360(0.72)³ = 134.47 = 134

Therefore, the analyst believes the value of the stock at the end of three weeks will be $134.

The population of Luis’s city in 2005 was 7400 and the population in 2010 was 9000. Let x represent the number of years since 20

podryga [215]

Answer:

The linear equation is;

y = 320x + 7400

Step-by-step explanation:

Here, we want to write a linear equation that represents the population y at a year since 2005

To write this, we need points

Initially, we have (0,7400)

Since the difference between 2005 and 2010 is 5, the second point will be (5,9000)

Mathematically, we can get the slope as follows;

m = (y2-y1)/(x2-x1) = (9000-7400)/(5-0) = 1,600/5 = 320

The equation of the line can be represented using the general form as;

y = mx + b

where m is 320 and b is unknown

So we have the equation as;

y = 320x + b

we need to get b

To get b, we can use any point

let us use the point (0,7400)

substituting this;

7400 = 320(0) + c

c = 7400

so the equation is;

y = 320x + 7400

What is the answer to this picture? Thanks to anyone who helps!

Nastasia [14]

A) 3000 * 0.5 = 1500 minutes, or 25 hours.
b) 10,000 * 0.5 = 5000 minutes, or 83 hours and 20 minutes
c) she works 2 hours a weekday. 2 hours = 120 minutes. It takes her 83 hours and 20 minutes to finish a 10,000 piece puzzle. It will take her 42 weekdays to finish this. Jan 15, 2020 is a Wednesday. She will finish it on March 12, 2020.
