The graph of the function f(x)=x^2-6x shifted 2 units to the left on the graph of g(x). Select the two functions that represent the shift of f(x) onto g(x)
Answer:
Step-by-step explanation:
g( x ) = f ( x + 2 )
g(x) = ( x + 2 )² - 6 ( x + 2 )
g(x) = x² + 4x + 4 - 6x - 12
g(x) = x² - 2x - 8

Answer:
9 ft.
Step-by-step explanation:
Rectangular Prism’s Volume:
[tex]\displaystyle \large{V=\sf{width*length*height}}[/tex]
Given:
width = 2.1 ft
length = 4 ft
height = j
volume = 75.6 cubic feet
Therefore, apply given information in the formula:
[tex]\displaystyle \large{75.6=2.1*4*j}\\\displaystyle \large{75.6=8.4j}[/tex]
Divide both sides by 8.4 to solve for j.
[tex]\displaystyle \large{\dfrac{75.6}{8.4}=\dfrac{8.4j}{8.4}}\\\displaystyle \large{\dfrac{75.6}{8.4}=j}\\\therefore \displaystyle \large{j=9}[/tex]
Henceforth, the value of j is 9 feet.

The bulletin board is in the shape of a square. Find two rational numbers that are within 1/8in. of the actual side length.
Answer:
And the answer may be 3/8 and 11/8 (among an infinite amount of different rational numbers less than 188 of the actual side length), as shwon below.
Explanation:
1) Calculate the side length of the bulletin board in the shape of a square:
The area of a square is equal to the square of length of the sides
A = x²
Substitute A = 150 unit²
150 = x²
Extract square root of both sides:
2) Find two rational numbers that are within, this is they are less than, 1/8 of the actual side length:
Since, 12² = 144 and 13² = 169, the square root of 150 is between 12 and 13.
Then, you can pick any two whole numbers less than 13 and multiple them by 1/8.
Remember that multiplying by 1/8 is the same that dividing by 8.
Choose 12 and 11, for instance, and two rational numbers that are less than 1/8 of the actual side length are 12/8 and 11/8.
12/8 can be simplified to 3/2 and 11/8 is in its simplest form.
Thus, two rational numbers that are within 1/8 of the actual side length of the bulletin board are 3/2 and 11/8.

Find the circumference of this circle. Use 3.14 to approximate T.
C = 27r
14 ft
C = [ ? ] ft
Answer:
43.98229 ft
Step-by-step explanation:
The diameter is 14ft, meaning the radius, which is half of it, is 7ft. Plug 7 into the r. C= 2pi(7) which 14pi. Now you multiply 14 by 3.14, which is the value of pi, and round it to whatever you need to give you your value.
The value of circumference of this circle is,
⇒ circumference = 14π ft
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Diameter = 14 ft
Hence, We get;
Radius = 7 ft
Thus, The value of circumference of this circle is,
⇒ circumference = 2πr
⇒ circumference = 2 × π × 7
⇒ circumference = 14π ft
Thus, The value of circumference of this circle is,
⇒ circumference = 14π ft

Write the absolute value equations in the form |x-b|=c (where b is a number and c can be either a number or an expression) that have the following solution sets. Two solutions: x=2, x=14
Answer:
|x - 8| = 6
Step-by-step explanation:
|x - b| = c
⇒ (x - b)² = c²
Given:
x = 2x = 14Substitute the values of x into (x - b)² = c²:
(2 - b)² = c²
(14 - b)² = c²
Equate and solve for b:
(2 - b)² = (14 - b)²
⇒ 4 - 4b + b² = 196 - 28b + b²
⇒ 4 - 4b = 196 - 28b
⇒ 24b = 192
⇒ b = 8
Substitute b = 8 into the equations to find c:
x = 2 ⇒ |2 - 8| = 6
x = 14 ⇒ |14 - 8| = 6
Therefore, c = 6
Final equation: |x - 8| = 6

Using correlation coefficients, it is found that the value of r is greater than 0 and close to 1, as the scatter-plot is increasing linearly.
What is a correlation coefficient?It is an index that measures correlation between two variables, assuming values between -1 and 1.If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.Researching the problem on the internet, it is found that the relation is modeled by an increasing scatter-plot, hence r > 0. There are very few points in which there are oscillations, which indicate a strong relationship, hence r is closer to 1.

Find the formula for an inverse proportion, knowing that its
graph goes through the point:
C(-25, -0.2)
The formula for an inverse proportion, knowing that its graph goes through the point: C(-25, -0.2) is y=5/x.
What is inversely proportional relationship?Let m and n are two variables.
Then m and n are said to be inversely proportional to each other if
[tex]m = \dfrac{c}{n} \\\\ \text{or} \\\\ n = \dfrac{c}{m}[/tex]
(both are equal)
where c is a constant number called constant of proportionality.
This inversely proportional relationship is denoted by
[tex]m \propto \dfrac{1}{n} \\\\ \text{or} \\\\n \propto \dfrac{1}{m}[/tex]
As visible, increasing one variable will decrease the other variable if both are inversely proportional.
The formula for the inverse function is given as,
[tex]y=\dfrac{c}{x}[/tex]
Here, c is constant.
The graph goes through the point: C(-25, -0.2). For the inverse function.
[tex]-25\propto\dfrac{1}{-0.2}\\-25=\dfrac{c}{-0.2}\\c=-25\times-0.2\\c=5[/tex]
Put the value in the above function,
[tex]y=\dfrac{5}{x}[/tex]
This is the required function.
Hence, the formula for an inverse proportion, knowing that its graph goes through the point: C(-25, -0.2) is y=5/x.
