The parent function f(x) = x^2 is vertically stretched by a scale factor of 2, translated 14 units right, and 6 units up. Which equation below represents the new equation? 1. G(x) = 2(x-14)^2 + 6 2. G(x) = 1/2 (x-14)^2 = 6 3. G(x) = 2(x-14)^2 - 6 4. G(x) = 2(x+14)^2 + 6
Answer:
[tex](1)\; G(x)=2(x-14)^2+6[/tex]
Step-by-step explanation:
Assuming, right and up are positive directions.
The given parent function, [tex]f(x)=x^2[/tex]
Let [tex]f_1(x)[/tex] be the function when the parent function is stretched by a scale factor of 2.
So, [tex]f_1(x)=2f(x)[/tex]
[tex]\Rightarrow f_1(x)=2x^2[/tex]
Let [tex]f_2(x)[/tex] be the function when [tex]f_1(x)[/tex] is translated [tex]14[/tex] units right.
So, [tex]f_2(x)=f_1(x-14)[/tex]
[tex]\Rightarrow f_2(x)=2(x-14)^2[/tex]
Again, let [tex]f_3(x)[/tex] be the function when [tex]f_2(x)[/tex] is translated 4 units up.
So, [tex]f_3(x)=f_2(x)+6[/tex]
[tex]\Rightarrow f_3(x)=2(x-14)^2+6[/tex]
So, the resulting function, [tex]f_3(x)=G(x)=2(x-14)^2+6[/tex].
Hence, option (1) is correct.
The annual profit at a chain of stores is normally distributed with a mean of $61,000 and a standard
deviation of $23,000. The stores in the top 5% of annual profit were rewarded with a celebration. What
was the annual profit required to have a party?
Answer: $98,835.
Step-by-step explanation:
Given: Annual profit at a chain of stores is normally distributed with a mean ([tex]\mu[/tex]) of $61,000 and a standard deviation([tex]\sigma[/tex]) of $23,000.
Let [tex]x[/tex] denoted the profit.
Let [tex]x_0[/tex] be the minimum profit required to have a party.
The stores in the top 5% (i.e. 0.05) of annual profit were rewarded with a celebration.
i.e. [tex]P(x>x_0)=0.05[/tex]
[tex]\Rightarrow\ P(\dfrac{x-\mu}{\sigma}>\dfrac{x_0-61000}{23000})=0.05\\\\\Rightarrow\ P(z>\dfrac{x_0-61000}{23000})=0.05\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\\Rightarrow\ \dfrac{x_0-61000}{23000}=1.645\ \ [\text{critical z-value for p-value 0.05=1.645}]\\\\\Rightarrow\ x_0-61000 =1.645\times 23000\\\\\Rightarrow\ x_0-61000 =37835\\\\\Rightarrow\ x_0=37835+61000\\\\\Rightarrow\ x_0=98835[/tex]
Hence, the annual profit required to have a party was $98,835.

Michelle is making a poster for a class presentation. She plans to have four sections of information, each with a different background color. The diagram shows the lengths and widths of each section, where a is the length of the red section. Which expression for the area of the poster is written as the sum of the areas of each colored section? (answer choices are in the screenshot provided. thanks! <3)
Answer:
first option
Step-by-step explanation:
the area of a rectangle is
base*height
[tex]Purple=(3)\times(a)\\\\=3a\\\\\\Green=(\frac{1}{2})\times(3)\\\\=\frac{3}{2}\\\\\\Red=1\times a\\\\=a\\\\\\Yellow=\frac{1}{2}\times 1\\\\=\frac{1}{2}[/tex]
so the sum is
[tex]\Sigma A=3a+a+\frac{3}{2}+\frac{1}{2}[/tex]
which is the first option
The expression for the area of the poster is written as the sum of the areas of each colored section is 3a + a + 3 1/2 + 1/2
Area of a rectangle = length × width
Purple color:
Area = length × width
= 3 × a
= 3a
Red color:
Area = length × width
= 1 × a
= a
Green color:
Area = length × width
= 3 × 1/2
= 3 1/2
Yellow color:
Area = length × width
= 1 × 1/2
= 1/2
Sum of the areas = purple + red + green + yellow
= 3a + a + 3 1/2 + 1/2
Therefore, expression for the area of the poster is written as the sum of the areas of each colored section is 3a + a + 3 1/2 + 1/2

A function assigns the values. The correct options are C and E.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
An equation is said to be a function if for each different value of x(input) it should give a different output. Therefore, for different inputs of x, the value of the output y should be different and unique. Also, the values if the equation produces the same output for two values of x it also said to be a function.
A.)
x = 3, since for every value of x the value is 3, which is not possible. Hence, this is not a function.
B.)
x² + y² = 81
For the given equation if the value of x is given as 0, the value of y will be,
x² + y² = 81
0² + y² = 81
y² = 81
y = ±√81
y = -9, 9
Hence, this can not be a function.
C.) y = -x + 11
For the given equation if the value of x is kept anything the value of y will be different. Thus, this is a function.
D.)
y² = -5x - 12
For the given equation if the value of x is given as less than -2.4, there will be two values of y. Thus, the given equation is not a function.
E.)
y = 2x² - 6x + 4
The given function will return will the same value of y for 2 different values of x. Hence, this is a function.
F.)
y = -7
Since the given equation can only have the value of y as 7. Therefore, it is not a function.
Hence, the equations that are a function are y = -x + 11 and y = 2x² - 6x + 4.

5-(x-6)=-7+3(-x+2)
Answer:
x=-6
Step-by-step explanation:
For this equation, when we remove the parenthesis, we get 5-x+6=-7+-3x+6.
Then we simplify both sides of the equation, so we get 11-x=-1-3x. When we separate the numbers and variables, we get -12=-2x. -12/2 = -6.

Olly took a taxi 12 miles and paid $8.40. The cab driver charges $0.45 per mile after a flat fee. How much would it cost if Olly needed to take the taxi for 25 miles?
Answer:
$14.25
Step-by-step explanation:
12 x 0.45 = 5.4
8.40-5.40=3
3 is the flat fee
3+(0.45 x 25) = 14.25
Answer:
$14.25
Step-by-step explanation:
8.40 = .45(12) + b
8.40 = 5.4 + b
b = 3
b = .45(25) + 3
b = 11.25 + 3
b = 14.25

What strategy would be the best to solve this problem? Ann-Marie bought apples. She kept one-third for herself and gave the rest to 4 friends. Each friend got 2 apples. How many apples did Ann-Marie buy? A. guess, check and revise B. work backwards C. use a formula D. look for patterns
Answer:
D. Look for patterns
Step-by-step explanation:
To solve :
Assume number of apples bought = x
Fraction kept = 1/3 of x
Fraction shared = (x - x/3) = (3x - x) /3 = 2x/3
Number of people who shared (2x/3) = 4 with each getting 2
Total number shared = 4 * 2 = 8
Fraction shared = total shared
2x/3 = 8
Multiply both sides by 3
(2x/3) * 3 = 8 * 3
2x = 24
x = 12
Hence, Anne-Marie purchased 12 apples
