The G(x) is the new function of the f(x) which is translated 4 units down is 4x²+2.
What is Function?A function assigns the value of each element of one set to the other specific element of another set.
The given function can be transformed from the initial position of the new position by subtracting the 4 from the initial function.
We know that in the initial function y=4x²+6, y is the output, while x is the input for the function f(x).
As the G(x) is the new function of the f(x) which is translated 4 units down. therefore,
[tex]G(x) = f(x)-4\\\\G(x) = 4x^2+6-4\\\\G(x) =4x^2+2[/tex]

What is the average distance from the mean, using this data? 10, 8, 5, 12, 20
Hey there!
• When you hear the word “mean” in mathematics it usually defined as “average”.
• To find it you have to ADD all of the numbers DIVIDE all of the numbers you have in the given data plot.
YOUR EQUATION:
10 + 8 + 5 + 12 + 20 / 5
= 18 + 5 + 12 + 20 / 5
= 23 + 12 + 20 / 5
= 35 + 20 / 5
= 55 / 5
= 11
Therefore, your answer is: 11

Answer:
50x + 4.75 ≤ 200
Step-by-step explanation:
Let x = number of Adele tickets
Cost of 1 Adele ticket = $50
One-time service fee = $4.75
Therefore, 50x + 4.75 ≤ 200

Answer:
mean = 24
Step-by-step explanation:
From inspection, there are 7 values.
The values are 12, 13, 15, 28, 28, 30, 42
To find the mean, sum the numbers: 12 + 13 + 15 + 28 + 28 + 30 + 42 = 168
Divide by the number of values: 168 ÷ 7 = 24
Therefore, mean = 24

Rohan draws a circle of radius 10 cm with the help of compass and scale. He also draws two chords, AB and CD in such a way that AB and CD are 6 cm and 8 cm from the centre O. Now, he has some doubts that are given below. Help him out by answering these questions:
a)what will be the chord of ab?
b)what wil be the chord of cd?
Answer:
a) 16 cmb) 12 cmStep-by-step explanation:
Connect the center with A and C:
OA = 10 cm or OC = 10 cmUse Pythagorean to find half of AB:
[tex]AB/2=\sqrt{10^2-6^2} =\sqrt{64} =8[/tex][tex]AB = 16[/tex]Similarly, find the length of CD:
[tex]CD/2=\sqrt{10^2-8^2} =\sqrt{36} =6[/tex][tex]CD=12[/tex]
Length of AB = 16 cm
h² = p² + b²
10² = 6² + b²
100 = 36 + b²
[tex]b = \sqrt{64} [/tex]
[tex]= 8 cm[/tex]
[tex]AB = 8 + 8[/tex]
[tex]= 16 cm[/tex]
Write an expression for the area of the shaded region in its simplest form. Show all of your steps. Show your work!
Answer:
[tex]A=x^2+23x+49[/tex]
Step-by-step explanation:
Hi there!
The area of the shaded region is equal to the area of the big rectangle minus the area of the square.
Area of the big rectangle:
[tex]A=lw\\A=(x+10)(2x+5)[/tex]
Area of the square:
[tex]A=a^2\\A=(x+1)^2[/tex]
Area of the shaded region:
[tex]A=(x+10)(2x+5)-(x+1)^2[/tex]
Expand:
[tex]A=(x+10)(2x+5)-(x+1)^2\\A=2x^2+5x+20x+50-(x+1)^2\\A=2x^2+5x+20x+50-(x^2+2x+1)\\A=2x^2+5x+20x+50-x^2-2x-1[/tex]
Combine like terms:
[tex]A=2x^2-x^2+5x+20x-2x+50-1\\A=x^2+23x+49[/tex]

Calculate the difference between the 10th term and 50th term of the sequence 9,14,19,24, ... ...
Answer:
Step-by-step explanation:
Number series : 9, 14, 19, 24
First term = a1 = 9
common difference = a2 - a1 = 14 - 9=5
Find the nth term:
an = a1 + + (n - 1)d
an = 9+ (n - 1)(5)
an = 9+5n - 5
an = 4 + 5n
Find the 10th term:
an = 4 + 5n
a10 = 4 + 5(10)
a10 = 4 + 50
a10 = 54
Find the 50th term:
an = 4 + 5n
a50 = 4 + 5(50)
a50 = 254
Find the difference between the 10th and
50th term:
Difference = 254 - 54 = 200
Answer: The difference is 200
Given the data from the question, the difference between the 10th term and the 50th term is 200

Answer:
[tex]y = \frac{4}{3}x + 2[/tex]
Step-by-step explanation:
Find the equation for the line in slope-intercept form: [tex]y = mx + b[/tex]
where m is the slope (gradient) and b is the y-intercept.
To find the slope (m)
Choose 2 points on the line: (0, 2) and (6, 10)
Let (0, 2) = [tex](x_1,y_1)[/tex]
Let (6, 10) = [tex](x_2,y_2)[/tex]
Use the slope formula: [tex]m=\frac{y_2-y_1}{x_2-x_1} =\frac{10-2}{6-0} =\frac{4}{3}[/tex]
Therefore, [tex]y = \frac{4}{3}x + b[/tex]
To find the y-intercept
The y-intercept is when x = 0 (where the line intersects the x-axis).
By inspection, the line intersects the y-axis at y = 2.
Therefore, y-intercept = 2
So, [tex]y = \frac{4}{3}x + 2[/tex]
