By rotating the picture counterclockwise, it is clear that it is a square.

Calculate the length of one side of the picture by using coordinates (1, -3) and (2,1).
a = [(2-1)^2 + (1+3)^2]^0.5 = (1 + 8)^0.5 = 3
The area of the picture is 3^2 = 9.

Calculate the area of the red paper.
Area = 8*8 = 64 

Calculate the area of the red paper after the photograph has been cut.
Area = 64 - 9 = 55

Answer:  55

Find the range. 4.7 6.3 5.4 3.2 4.9 3.1 –3.1 9.5 –9.5
WINSTONCH [101]

Answer:

The range is 19

Step-by-step explanation:

First, you have to order the numbers from least to greatest:

-9.5, -3.1, 3.1, 3.2, 4.7, 4.9, 5.4, 6.3, 9.5

Then, you have to find the difference between the largest number and and smallest number. You do this by subtracting them:

9.5 - (-9.5)= 19

So, the range is 19

Given the Arithmetic sequence A1,A2,A3,A4 61, 74, 87, 100 What is the value of A15?
Rufina [12.5K]
A15=243
74-61=13
87-61=13
So they're adding 13 every time.
A15 is 11 terms from A4 which is the last one you are given so 11*13=143
143+100=243

2. Us i ng the filled table above,
VARVARA [1.3K]

The price elasticity of demand of the pen will be -0.2.

<h3>How to compute the elasticity?</h3>

The demand and supply schedule will be:

Price Qd. Qs

$10. 250. 100

$20. 200. 90

$30. 180. 80

The price elasticity of demand from $1 to $2 will be:

= Percentage change in quantity demanded/percentage change in price

Percentage change in quantity demanded will be:

= (200 - 250)/250 × 100

= -20%

Percentage change in price will be:

= (20 - 10)/10 × 100

= 100%

Therefore, the elasticity of demand will be:

= -20/100

= - 0.2

The value gotten illustrates an inelastic demand.

In order to increase the total revenue, the price can be reduced as it will lead to more sales.
