What is the equation for the graph?
Answer:
Standard Form:
[tex]y = {x}^{3} - 3 {x}^{2} + 3x - 4[/tex]
Another Form:
[tex]y = (x - 1)^{3} - 3[/tex]
Step-by-step explanation:
The type of graph or function is called Cubic Function
The type of graph is represented by the equation of y = a(x-h)³+k
Thus our equation for the graph is
[tex]y = {(x - 1)}^{ 3} - 3[/tex]
In case if you want standard form.
Simplify the expression.
[tex](x - y)^{3} = {x}^{3} - 3 {x}^{2} y + 3x {y}^{2} - {y}^{3} [/tex]
[tex]y ={x}^{3} - 3 {x}^{2} + 3x - 1 - 3 \\ y = {x}^{3} - 3 {x}^{2} + 3x - 4[/tex]
The graph shows the amount of money left after buying video games. Find the slope of the line
Answer:
It’s -20
Step-by-step explanation:
The slope of the line is m = -20.
What is the slope?The ratio of the vertical and horizontal changes between two points on a surface or a line is known as the slope.
Note that the graph passes through points (2,80) and (4,40).
The formula for the slope of a line passing through the points (x₁,y₁) and (x₂,y₂) is:
m = (y₂-y₁)/(x₂-x₁)
Substitute the points (x₁,y₁) = (2,80) and (x₂, y₂) = (4,40) into the above equation:
m = (40 - 80)/(4 - 2)
m = -40/2
m = -20
Hence, the slope of the line is m = -20.

Annapurna suppliers sold construction materials at Rs. 497200 to Sagarmatha suppliers
making 10% profit and adding 13% VAT. Find the cost price of the Annapurna suppliers.
Sagarmatha suppliers spent Rs 10000 for transportation cost and made Rs. 30000 profit and
levied local tax Rs. 20000 and sold to constructor. Find the additional VAT applicable amount
and the final price with VAT
Step-by-step explanation:
annapurna suppliers to sagarmatha suppliers ,
SP = (100+10)%of 497200
=110/100 * 497200
SP = RS. 546920
VAT 1 = 13% OF 546920
= RS. 71099.6
SAGARMATHA SUPPLIERS TO CONSTRUCTOR,
CP=RS.546920
TC=RS.10000
PROFIT =RS. 30000
LT =RS. 20000
SP = RS. 60000
VAT=13%
VAT 2 = 13% OF 60000
= RS. 7800
final price with VAT = 7800+ 546920+71099.6
=RS. 625819.6
Final cost is 36463.6 and VAT end profit is 3646.36.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given
Material cost = 497200
10% profit = [tex]\frac{10}{100}[/tex] × 497200
= 49720
13% VAT = [tex]\frac{13}{100}[/tex] × 49720
= 6463.6
Hence, Final cost = 6463.6 + 10000 + 20000
= 36463.6
VAT end profit = [tex]\frac{10}{100}[/tex] × 36463.6
= 3646.36
Hence, Final cost is 36463.6 and VAT end profit is 3646.36.

Bill charges $12 per hour for a plumbing job. Write the equation that shows the relationship between the numbers of hours Bill work's,h, and the amount of money he makes, m?
Answer:
m = 12h
Step-by-step explanation:
Since Bill charges $12 per hour, it implies for every hour he charges $12. Therefore, the amount of money he makes, m, is dependent on the number of hours he works, h. The higher the number of hours, the more his money. And vice versa.
So that;
m = 12h
Thus if Bill works for 6 hours, his amount of money would be;
m = 12 (6)
= 72
m = $72
Bill would make $72 after working for 6 hours.

Megan ran 9/12 of a mile and skips a 12th of a mile around the track how far around the track did Megan go in total use the benchmarks fraction 1/2 1 and 0 to help you estimate each answer before you solve
Answer:
She went a total of 5/6 of a mile around the track
Step-by-step explanation:
Here, we want to calculate the distance around the track travelled
From the question, we are told that she ran 9/12 of a mile and skipped 1/12
So the total distance covered will be;
9/12 + 1/12 = 10/12 = 5/6

Given that u, = -3,
a) find u,
b) find uz
Answer:
Please check the explanation.
Step-by-step explanation:
a)
A sequence is defined by the term-to-term rule such as
[tex]U_{n+1}=U^3_n+2[/tex]
Given that
[tex]U_0=-3[/tex]
Substituting n = 0 to determine u₁
[tex]U_{0+1}=U^3_0+2[/tex]
[tex]U_1=U^3_0+2[/tex]
substituting [tex]U_0=-3[/tex]
[tex]U_1=\left(-3\right)^3+2[/tex]
[tex]U_1=-27+2[/tex]
[tex]U_1=-25[/tex]
Therefore,
[tex]U_1=-25[/tex]b)
[tex]U_{n+1}=U^3_n+2[/tex]
Substituting n = 1 to determine u₂
[tex]\:U_{1+1}=U^3_1+2[/tex]
substituting [tex]U_1=-25[/tex]
[tex]U_2=\left(-25\right)^3+2[/tex]
[tex]U_2=-15625+2[/tex]
[tex]U_2=-15623[/tex]
Therefore,
[tex]U_2=-15623[/tex]
Find the length of DE using the distance formula. d =
Answer:
d = 10units
Step-by-step explanation:
The question is incomplete. Find the complete question attached
The formula for calculating the distance between two points is expressed by the formula;
d = √(x₂-x₁)²+(y₂-y₁)²
Given the coordinate points (-4, 2) and (4, -4)
d = √(4-(-4))²+(-4-2)²
d = √(4+4)²+(-6)²
d = √(8)²+(-6)²
d = √64+36
d = √100
d = 10
Hence the distance between the points DE is 10units

-10 -8 -6 -4-2 0 2 4 6 8 10
Answer:

Step-by-step explanation:
Given
| - 2x | = 4
The absolute value function always gives a positive result, however, the expression inside can be positive or negative , that is
- 2x = 4 or - (- 2x) = 4
Solving both
- 2x = 4 ( divide both sides by - 2 )
x = - 2
or
- (- 2x) = 4
2x = 4 ( divide both sides by 2 )
x = 2
The third graph indicates x = - 2 and x = 2 on the number line

A builder is building a fence with 6 LaTeX: \frac{1}{4}1 4 inch-wide wooden boards, arranged side-by-side with no gaps. How many boards are needed to build a fence that is 150 inches long?
Answer:
24 boards
Step-by-step explanation:
From the above question, the width of a wooden board for a fence = 6 1/4 inches
How many boards are needed to build a fence that is 150 inches long?
This is calculated as:
6 1/4 inches = 1 board
150 inches = x
Cross Multiply
6 1/4 × x = 150 × 1
x = 150 ÷ 6 1/4
x = 150 ÷ 25/4
x = 150 × 4/25
x = 24 boards
Hence, 24 boards would be needed to build a fence that is 150 inches long
Find the equation of the line that is perpendicular to the given line and passes through the given point. Enter your answer in slope intercept for (y=mx+b) with the values of m and b given as decimals, rounded to the nearest hundredth if necessary. y=20x;(2,2)
The equation is y =
Please help very urgent! :)
Answer:
y = - 0.05x - 1.9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
y = 20x ← is in slope- intercept form
with slope m = 20
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{20}[/tex] = - 0.05 , thus
y = - 0.05x + b ← is the partial equation
To find b substitute (2, - 2) into the partial equation
- 2 = - 0.1 + b ⇒ b = - 2 + 0.1 = - 1.9
y = - 0.05x - 1.9 ← equation of perpendicular line
Which polynomial function f(x) has a leading coefficient of 1, roots4, 2, and 9 with multiplicity 1, and root-5 with
multiplicity 3?
Answer:
[tex]x^6-88x^4-142x^3+1695x^2+2350x-9000[/tex]
Step-by-step explanation:
In order to solve this function, we must first start by writting the factors of the polynomial. We can do so by including the given zeros, and the leading coefficient. So we get:
[tex]f(x)=1(x-4)(x-2)(x-9)(x+5)^{3}[/tex]
and now we can expand this by multiplying the given parenthesis, so we get:
[tex]f(x)=(x^2-2x-4x+8)(x-9)(x^3+3(5)x^{2}+3(25)x+125)[/tex]
[tex]f(x)=(x^2-6x+8)(x-9)(x^3+15x^{2}+75x+125)[/tex]
[tex]f(x)=(x^3-9x^2-6x^2+54x+8x-72)(x^3+15x^{2}+75x+125)[/tex]
[tex]f(x)=(x^3-15x^2+62x-72)(x^3+15x^{2}+75x+125)[/tex]
[tex]f(x)=x^6+15x^5+75x^4+125x^3-15x^5-225x^4-1125x^3-1875x^2+62x^4+930x^3+4650x^2+7750x-72x^3-1080x^2-5400x-9000[/tex]
we combine like terms so we get:
[tex]x^6-88x^4-142x^3+1695x^2+2350x-9000[/tex]
