In other words, Ax² + Bx + C is a perfect square.

construct the graph of x^2+y^2=9 what would this graph look like and what are its coordinates please help?

Answers

Answer:

The coordinates (3,0), (-3,0), (0,3) ,and (0,-3) helps us to draw the graph of the circle. Below is the explanation

Step-by-step explanation:

Given:

The equation of a circle is $x^(2) +y^(2) =9$ .

To find:

Graph the given equation.

Let's find the center and radius by comparing the given equation with the standard form.

$(x-h)^(2) +(y-k)^(2) =r^(2)$

We can rewrite our equation as $(x-0)^(2)+ (y-0)^(2)= 3^(2)$

Now, compare them

$(x-h)^(2) +(y-k)^(2) =r^(2)$

$(x-0)^(2)+ (y-0)^(2)= 3^(2)$

Center (h,k)=(0,0)

Radius r=3

Now, draw the graph of the circle by placing the center and radius.

So, the coordinates which are 3 units exactly from the center (0,0) help us to find the graph of the circle. So, (0,3), (0,-3), (3,0) ,and (-3,0) would help us to graph the circle.

A micrometer is one-millionth of a meter (0.000001): ten thousand times shorter than a centimeter (0.01). How many micrometer one is one edge of a centimeter cube?

Answers

Answer:

$1cm^3=0.000000000001mm^3$

Step-by-step explanation:

Given : 0.000001 mm = 0.01 cm

To find : How many $mm^3$ is in $1 cm^3$

Solution :

Step 1 : Given 0.000001 mm = 0.01 cm

Step 2: Cubing both side $(0.000001mm)^3 = (0.01cm)^3$

Step 3: Solve $(10^(-6))^3mm^3=(10^(-2))^3cm^3$

$\Rightarrow((10^(-6))^3)/((10^(-2))^3)mm^3=1cm^3$

$\Rightarrow(10^(-18))/(10^(-6))mm^3=1cm^3$

$\Rightarrow 10^(-18+6)mm^3=1cm^3$

$\Rightarrow 10^(-12)mm^3=1cm^3$

$\Rightarrow 0.000000000001mm^3=1cm^3$

Therefore, $1cm^3=0.000000000001mm^3$

If a cube has an edge of one centimeter and one centimeter is ten thousand times longer than a micrometer, then the edge has ten thousand micrometers.

I hope that's what you meant :)

The formula for perimeter of a rectangle is given by p = 2l + 2w, where p = perimeter, l = length, and w = width. solve the formula for w.

Answers

Perimeter formula
p = 2l + 2w

I reverse left-right side
2l + 2w = p

Move 2l to the right
2l + 2w = p
2w = p - 2l

Move 2 to the right
2w = p - 2l
w = (p - 2l)/2

Summary
p = 2l + 2w
2l + 2w = p
2w = p - 2l
w = (p-2l)/2
