Step-by-step explanation:
if y=3x^2
if x is 1 y is 3 because if you substitute x for 1, 1^2 = 1, And 3•1 = 3
if x is 2 y is 12 because if you substitute x for 2, 2^2 = 4 and 3•4 =12
Keep going using this formula, You can go into the negatives by substituting x for a negative number aka -1 or -2
ok ok this is the last one finally

The diameter of a circle is 20 m. Find its area in terms of π
Answer:
100π m^2
Step-by-step explanation:
Given data
Diameter= 20m
Radius= 10m
The expression for the area is
Area= πr^2
Area= π*10^2
Area= π*100
Area= 100π m^2
Hence the area is 100π m^2

3x-8y=24
y=x-8
Please show
work
Answer:
3x - 8y = 24 --------(1)
y = x - 8 ---------(2)
substitute y in (1)
3x - 8( x - 8) = 24
3x - 8x + 64 = 24
-5x = 24 - 64
-5x = -40
5x = 40
x= 8
substitute x in (2)
y = 2 - 8
y = - 6
Answer:
x = 8, and y = 0
Step-by-step explanation:
We can solve this by taking y as (x-8), as it states there.
Since y is equal to x-8, we can rearrange the system of equations into one single equation.
We can multiply y by 8, as it shows in the first equation, which is something like 8x-64.
Since it is a negative 8 being multiplied by y, it would be the inverse of 8x-64, which is -8x+64.
We can now organize our equation here.
3x - 8x + 64 = 24.
We can use subtraction property of equality by subtracing 64 from both sides to get rid of it.
We will get something like:
3x - 8x + 64 - 64 = 24 - 64.
Simplify by solving like terms like the x value and the integers.
-5x = -40
Divide both sides with division property of equality:
-5/5x = -40/5
x = 8
We can then plug the 8 back into x, lets use the second equation because I'm lazy and it looks the easiest to solve for.
y = (8) - 8
y = 0
Therefore, x = 8, and y = 0.
Find the missing side of the triangle.

A volume of the cone is (1/3) the volume of a cylinder. The volume of the sphere is what fraction of the volume of the cylinder?
Answer:
4/3
Step-by-step explanation:
To know this, let's write down the formulas for the volume of cylinder and sphere.
Vs = 4/3πr³ (1)
Vc = π r² h (2)
Now, we do have a little problem here and its the fact that the sphere do not have a height like the cylinder do. But in this case so if you want to have an idea of the fraction of the volume, we will assume that the cylinder has the same height as its radius. Assuming this we have the following:
Vs / Vc = 4πr³ / 3πr²h
Vs/Vc = 4πr³ / 3πr³
From here, we can cancel out the values of π and r³:
Vs/Vc = 4/3
Vs = 4/3 VcThus we can conclude that the volume of the sphere is 4/3 the volume of a cylinder.

Find the area of a square with a diagonal of length 12.
Answer:
6
Step-by-step explanation:
Answer:
72 square units
Step-by-step explanation:
you can use the Pythagorean Theorem; because we're dealing with a square then each side can be assigned the same variable, let's use 'a'
a² + a² = 12²
2a² = 144
a² = 72
a = [tex]\sqrt{72}[/tex]
[tex]\sqrt{72}[/tex] can be simplied as [tex]\sqrt{9}[/tex]·[tex]\sqrt{4}[/tex]·[tex]\sqrt{2}[/tex] which is 3·2·[tex]\sqrt{2}[/tex]
each side has a length of 6[tex]\sqrt{2}[/tex]
A = (6[tex]\sqrt{2}[/tex])² which is 6·6·2 or 72

The square pyramid below represents a tent that Wayne is making. The sides of the tent will be covered in blue fabric and the base of the tent will be covered in brown fabric. Find the surface area that will be covered in each color of fabric.
Answer:
The answer is below
Step-by-step explanation:
A square pyramid is a pyramid with a square base. Therefore it is composed of 4 identical triangles and a square base.
From the image attached:
Area of each of the triangle = (1/2) * 3 m * 4.5 m = 6.75 m²
Area of base = 3 m * 3 m = 9 m²
Since the sides are covered in blue fabric, hence:
Surface area of blue fabric = 4 * area of each triangle = 4 * 6.75 m² = 27 m²
The base is covered with brown fabric, hence Surface area of brown fabric = 4 * area of each triangle = 4 * 9 m² = 36 m²

Answer:
Slope: 5, Y-intercept: 150
Step-by-step explanation:
=> Slope = Change in y / Change in x
Change in y = +35
Change in x = +7, therefore;
Slope = 35 / 7
Slope = 5
=> Y-intercept is the y-value where x = 0, therefore;
Y-intercept = 150

A.CED.1/A.REI.4 Tonya has a rectangular rug as shown. The rug is 4 feet longer than it is wide. (Part A) Create an expression that can be used to determine the length and the width of the rug. Write your answers in terms of x.
help me
Answer:
Width of the rug = x feet
Length of the rug = (x + 4) feet
Step-by-step explanation:
Let
Width of the rug = x feet
The rug is 4 feet longer than it is wide.
Length of the rug = (x + 4) feet
For instance, to find the area of the rug
Area of a rectangular rug = length × width
= (x + 4) * x
= x² + 4x
Area of a rectangular rug = x² + 4x
To find the perimeter of the rug
Perimeter of the rectangular rug = 2(length + width)
= 2{(x + 4) + x}
= 2(x + 4 + x)
= 2(2x + 4)
= 4x + 8
Perimeter of the rectangular rug = 4x + 8
