Central Park in New York City is shaped like a rectangle. On a map of the park

mariarad [96]

Answer:

Step-by-step explanation:

Given that the coordinate plane, three of the vertices of the rectangle are located at (-1.25, -0.25),

(-1.25, 0.25), and (1.25, 0.25)

The length L of the shape will be:

L = 0.25 - ( - 0.25 )

L = 0.25 + 0.25

L = 0.5

The width of the shape will be:

W = 1.25 - ( - 1.25)

W = 1.25 + 1.25

W = 2.5

Perimeter P = 2L + 2W

Substitute the Length and the width into the formula

P = 2(0.5) + 2(2.5)

P = 1 + 5

P = 6 metres

Therefore, the perimeter of the shape is 6 metres

a laptop computer is purchased for $4500. Each year, its value is 80% of its value the year before. After how many years will th

Answer:

So after 7 year price of the laptop will be less than $1000

Step-by-step explanation:

We have given price of the laptop is $4500

Its price is 80% of if its value in every next year

So depreciation rate = 100 - 80 =20%

For depreciation we know that

$V=P(1-r)^n$

Here V is final value and P is present value

So $1000=4500(1-0.2)^n$

$0.2222=(0.8)^n$

Taking log both side

$log0.222=nlog0.8$

n = 6.74

So after 6.74 year the price of the laptop will be less than $1000
