Answers:
In these exercices are ilustrated the representations of the fractions
2) Firstly, we have 3 equal segments, each one representing 
, hence:
is <u>3</u> copies of
Let's prove it, taking into account we are adding fractions with the same denominator:
There are <u>4</u> equal parts that make a whole
Four copies of <u></u> make 
or <u>1</u> whole
3) Here we have a line divided into four segments, each one of 
. Hence:
This is 
of a line. is <u>4</u> lengths of
If we draw one more we will have 
or 1 whole.
Then:
<u>5</u> lengths of make or <u>1</u> whole.
4) In this part the answer is in the attached image. If we have two equal segments, each one of 
we will have as a result 
.
If we add another segment, we will have three segments of , having as a result 
M = 1 - 2 / 3 - 1
m = - 1 / 2
Answer:
0.11
Step-by-step explanation:
The answer would be 0.11, i just used a calculator lol
This statment only works for linear systems because in non-linear systems it is okay to have more than one soultion
but if the system is linear than you can define it by it two soultions or in other words it takes two points to form a line and if two lines pass through the same points then you can define them by those point and they are the same line
A trig identity is <span>asinucosu=<span>a/2</span>sin(2u)</span>So you can write your equation as<span>y=sin(x)cos(x)=<span>1/2</span>sin(2x)</span>Use the crain rule here<span><span>y′</span>=<span>d/<span>dx</span></span><span>1/2</span>sin(2x)=<span>1/2</span>cos(2x)<span>d/<span>dx</span></span>2x=cos(2x)</span>The curve will have horizontal tangents when y' = 0.<span><span>y′</span>=0=cos(2x)</span>On the interval [-pi, pi], solution to that is<span><span>x=±<span>π4</span>,±<span><span>3π</span>4</span></span></span>
