Answer:
The series of transformations that apply are a vertical compression by a factor of 2 and a translation of 4 units down.
Step-by-step explanation:
In a slope-intercept function, the coefficient of the variable determines whether the graph opens up or down, as well as the amount it stretches. If a function's coefficient is greater than 1, as the value of the coefficient increases, the function becomes more vertically compressed. If a function's coefficient is less than 1 but greater than 0, as the coefficient gradually approaches 0, the function becomes more vertically stretched. Since the function's coefficient went from 1 to 2, that means the graph of the function is being vertically compressed by a factor of 2. A slope-intercept function's constant is the graph's y-intercept since the y-value would be that when x is equal to 0. Since the constant went from 0 to -4, that means the graph of the function has been translated down 4 units. So the correct choices would be a vertical compression by a factor of 2, and a translation of 4 units down.

Answer:
A = 250
B = 10
Step-by-step explanation:
Why A equals 250 is because 10 squared 5 equals 500 and 500 divided by 2 equals 250.
Why B equals 10 is because 10 minus 5 is 5 we do that first cause its in pentises and 10 squared times 2 equals 200 and 200 times 5 equals 1000 so 1000 divide 100 is 10

12years ago Justin Timberlake put money into an account paying 6.5% interest compounded biannually. If the account has $18,000 now, how much money did Justin Timberlake deposit?
Answer:
$8645.73
Step-by-step explanation:
Using the compound interest formula :
A = P(1 + r/n)^nt
A = final amount = 18000
r = rate = 6.5% = 0.065
n = number of compounding tines per period, biannually, once in 2 years = 0.5
18000 = P(1 + 0.065/0.5)^(0.5*12)
18000 = P(1 + 0.13)^6
18000 = P(2.081951752609)
18000 / 2.081951752609 = P
= 8645.7334
= $8645.73

Here is an expression: 2 + 3ⁱ ( Remember what you do when you replace i with a number) Evaluate the expression when i is 1.
Answer:
The value of the expression when i is 1 is equals to 5.
Step-by-step explanation:
We are given the following expression:
[tex]2 + 3^{i}[/tex]
Evaluate the expression when i is 1.
We replace i by 1. When we elevate a number to the 1, the result is the number we elevate. So
[tex]2 + 3^{i} = 2 + 3^{1} = 2 + 3 = 5[/tex]
The value of the expression when i is 1 is equals to 5.

. A football team had 52 players at the start of the season, but then some players left the team. After that, the team had 43 players.
Answer:
[tex]52-p<43[/tex]
Step-by-step explanation:
There was a total of 52 players but then some left the team. Since we don't know how many left, we use a variable. Left indicates subtraction, so the equation would be 52 - p.
However we still have the last sentence of the information. Since 43 players remain and we don't know how many players left, I put the '<' sign.
Thus, my answer was: [tex]52-p<43[/tex]

2. What is the domain of the function shown below?
у
A. -1 < x < 6
B. -1 < y = 6
C. -2 < x < 5
D. -1 3y = 6
Answer:
Option A is the correct answer
Step-by-step explanation:
[tex] - 1 \leqslant x \leqslant 6[/tex]
The domain of the function is -1 ≤ x ≤ 6 or x ∈ [-1, 6] option (A) -1 ≤ x ≤ 6 is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a given a graph of a function in the picture.
As we can see, the at point x = -1 graph starts, and it has dark dot which means function values exist at x = -1.
Similarly, at x = 6 the function value exist.
The domain of the function:
-1 ≤ x ≤ 6
Thus, the domain of the function is -1 ≤ x ≤ 6 or x ∈ [-1, 6] option (A) -1 ≤ x ≤ 6 is correct.

Which set of angle measures CANNOT be the angle measures inside of a triangle?
45°, 45°, 45°
60°, 75°, 35°
60.5°, 59.5, 59°
65°, 60°, 55°
Answer:
Therefore, option A,B and C cannot be the angles of triangles.
Step-by-step explanation:
Given that total angles in a triangle is 180° so you have to add up all the angles :
Option A,
45° + 45° + 45° = 135° (Not a triangle)
Option B,
60° + 75° + 35° = 170° (Not a triangle)
Option C,
60.5° + 59.5° + 59° = 179° (Not a triangle)
Option C,
65° + 60° + 55° = 180° (It is triangle)

A company makes Poppy Lapel Pins.
Each of them costs £1.30 to make.
In October it made 800 lapel pins.
25% of them are given to charities.
The rest are sold in two formats: 70% of them at £2.50 each
30% of them at £5.00 for 3
Assuming that all the lapel pins will be sold by the end of November,
work out the percentage profit the company should make.
Give your answer to 1 decimal place.
Please someone help it may have been answered before but it's hard to change the values at a certain stage. Thanks
Answer:
29.8%
Step-by-step explanation:
1.30 × 800 = £1040
25% of 800 = 200
800 - 200 = 600 poppy lapel pins given to the charity
70% of 600 = 420
420 × 2.50 = £1050
30% of 600 = 180
180÷3 = 60
60 × 5.00 = £300
[tex]\frac{1050+300-1040}{1040}[/tex] = 29.8076923
= 29.8% to one decimal place
I hope I helped :)
The company should make a percentage profit of approximately 29.8%.
Given that a company makes Poppy Lapel Pins.
Each of them costs £1.30 to make.
In October 800 lapel pins were made from which 25% were given to charities,
The rest are sold in two formats:
70% of them at £2.50 each
30% of them at £5.00 for 3.
We need to find the percentage profit the company should make.
To calculate the percentage profit, we first need to determine the total cost of manufacturing the lapel pins and the total revenue generated from their sales.
Total Cost:
Cost per lapel pin = £1.30
Number of lapel pins manufactured = 800
Total cost = £1.30 × 800 = £1040
Total Revenue:
Number of lapel pins given to charities = 25% of 800 = 0.25 × 800 = 200
Number of lapel pins available for sale = 800 - 200 = 600
Format 1:
70% of lapel pins sold at £2.50 each:
Number of lapel pins = 0.70 × 600 = 420
Revenue from this format = £2.50 × 420 = £1050
Format 2:
30% of lapel pins sold at £5.00 for 3:
Number of lapel pins = 0.30 × 600 = 180
Revenue from this format = (£5.00 ÷ 3) × 180 = £300
Total Revenue = Revenue from Format 1 + Revenue from Format 2 = £1050 + £300 = £1350
Profit:
Profit = Total Revenue - Total Cost = £1350 - £1040 = £310
Percentage Profit:
Percentage Profit = (Profit ÷ Total Cost) × 100
Percentage Profit = (£310 ÷ £1040) × 100 ≈ 29.8%
Therefore, the company should make a percentage profit of approximately 29.8%.
