Answer:

Mathematical expressions

Step-by-step explaniation:

In mathematics there basically two methods of writing mathematical terms either as a n expression or as an equation.. Mathematical terms with the equality signs are referred to as equations,while those without the equality signs are referred to as mathematical expressions. Example of mathematical equations are

2x+3y=4, 5g+4h=2

While for expressions we such terms as 2x, 5xy+6z.

Camille simplified an expression as shown. discuss why this method is justified. <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B
Burka [1]
We know that
\frac{ab}{cd} = \frac{a}{c} \times  \frac{b}{d}

Therefore
\frac{6\times10^{5}}{3\times10^{2}} = \frac{6}{3} \times  \frac{10^{5}}{10^{2}} =2 \times 10^{5-2} = 2 \times 10^{3} = 2000

This verifies that Camile's method is justified.

Rewrite the Cartesian equation y=-3 as a polar equation.

r

sin

θ

=

−

Explanation:

Imagine we have a point  

P

with Rectangular (also called Cartesian) coordinates  

(

x

,

y

)

and Polar coordinates  

(

r

,

θ

)

.

The following diagram will help us visualise the situation better:

https://keisan.casio.com/exec/system/1223526375

We can see that a right triangle is formed with sides  

x

,  

y

and  

r

, as well as an angle  

θ

.

We have to find the relation between the Cartesian and Polar coordinates, respectively.

By Pythagora's theorem, we get the result

r

2

=

x

2

+

y

2

The only properties we can say about  

θ

are its trigonometric functions:

sin

θ

=

y

/

r

⇒

y

=

r

sin

θ

cos

θ

=

x

/

r

⇒

x

=

r

cos

θ

So we have the following relations:

⎧

⎪

⎨

⎪

⎩

r

2

=

x

2

+

y

2

y

=

r

sin

θ

x

=

r

cos

θ

Now, we can see that saying  

y

=

−

in the Rectangular system is equivalent to say

r

sin

θ

=

−
