Give an example of a relation that is NOT a function and explain why it is not a function.I do not understand how to do this...please help its algebra.

Answers

Answer 1

Answer: The desired example is this: x=y^2
Because for each x>0 we have two different possible y values which means it is not a function anymore. a function should only maximum 1 y value for each x value.

You can see the above relation has multiple possible values for y because if we take x=1 then y can be -1 or 1.

The front and back covers of a textbook are each 0.3 cm thick. Between the covers are 200 sheets of paper, each 0.008 cm thick. How high is a stack of 10 books

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The height of the 10 stacks of books is 22cm.

What is multiplication?

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Given that the front and back covers of a textbook are each 0.3 cm thick. Also, there are 200 sheets of paper between the cover and the thickness of each sheet is 200 sheets. Therefore, the thickness of the book is,

The thickness of a single book

= (Number of covers × Thickness of cover) + (Number of sheets × Thickness of sheets)

= (2 × 0.3cm) + (200 × 0.008cm)

= 2.2 cm

Now, the thickness of 10 books will be,

The thickness of 10 books = 10 × the Thickness of a single book

= 10 × 2.2 cm

= 22 cm

Hence, the height of the 10 stacks of books is 22cm.

Answer:

22 cm

Step-by-step explanation:

Start off by multiplying the number of pages by the thickness.

200*0.008=1.6

Add the thickness of the front and back cover.

1.6+0.6=2.2

Multiply by 10.

2.2*10=22 cm

calculate areas
area of triangle=1/2bh
area of rectangle=bh

leftmost side

b=2
4*1/2*2*1.8=7.2 cm^2

middle recangles

other triangles

b=2
h=2.71
total area=4*1/2*2*2.71=10.84cm^2
add them up

7.2cm^2+24cm^2+10.84cm^2=42.04cm^2

Why did the French explore and colonize parts of North America? A.
to enslave Native Americans as workers in France

B.
to establish a democratic republic

C.
to build cattle ranches

D.
to look for gold and trap for furs

Answers

Answer:

Option D.

Step-by-step explanation:

To look for gold and trap for furs, is the right answer.

The French initially came to the United States as explorers, who were trying to find a route to the Ocean and resources. The French finally attempted to build some colonies throughout North America that abandoned, due to various reasons such as disease, weather or struggle with other European authorities. Though during the course of time, they established colonies in the Americas, their initial motive was to look for gold and trap for furs.

I think it would be b because that is what the french explores did back then
