The profit function for the first version of the device was very similar to the profit function for the new version. As a matter of fact, the profit function for the first version is a transformation of the profit function for the new version. For the value x = 40, the original profit function is half the size of the new profit function. Write two function transformations in terms of P(x) that could represent the original profit function.
Answers
Answer:
a) - Compressing the P(new) function by a scale of 0.5 about the y axis.
- Moving the P(new) function down by 104 units.
b) The two simplified functions for P(original)
-0.08x² + 10.8x – 200.
-0.16x² + 21.6x – 504.
Step-by-step explanation:
Complete Question
An electronics manufacturer recently created a new version of a popular device. It also created this function to represent the profit, P(x), in tens of thousands of dollars, that the company will earn based on manufacturing x thousand devices: P(x) = -0.16x² + 21.6x – 400.
a. The profit function for the first version of the device was very similar to the profit function for the new version. As a matter of fact, the profit function for the first version is a transformation of the profit function for the new version. For the value x = 40, the original profit function is half the size of the new profit function. Write two function transformations in terms of P(x) that could represent the original profit function.
b. Write the two possible functions from part a in simplified form.
Solution
The equation for the new profit function is
P(x) = -0.16x² + 21.6x – 400
At x = 40, the original profit function is half the size of the new profit function
First, we find the value of the new profit function at x = 40
P(x) = -0.16(40)² + 21.6(40) – 400 = 208
Half of 208 = 0.5 × 208 = 104
P(original at x = 40) = P(new at x = 40) ÷ 2
Since we are told that P(original) is a simple transformation of the P(new)
P(original) = P(new)/2 = (-0.16x² + 21.6x – 400)/2 = -0.08x² + 10.8x – 200 ... (eqn 1)
Or, P(original) = 104
-0.16x² + 21.6x – 400 = 104
P(original) = -0.16x² + 21.6x – 400 - 104 = -0.16x² + 21.6x – 504.
So, the two functions that are simple transformations of P(new) to get P(original) are
-0.08x² + 10.8x – 200
Obtained by compressing the P(new) function by a scale of 0.5 about the y axis.
And
-0.16x² + 21.6x – 504.
Obtained by moving the P(new) function down by 104 units.

Thus, slope of the line
[tex] = \frac{4 - ( - 4)}{2 - ( - 2)} \\ = \frac{4 + 4}{2 + 2} \\ = \frac{8}{4} \\ = 2[/tex]

1. It cost Nike $55 to make the "Kyrie 5", but it is selling for $130.19. Calculate the markup/percent Increase for the shoe.
2. The state tax is 8%. Calculate how much you will pay in taxes on the Kyrie 5.
3. You just found a coupon for 35% off! What is the new price of the shoe before taxes?
4. On Amazon, you found the same shoe for $108. What is the percent difference between the price of the original and the price of the amazon shoe?
Answers
Answer:
1)The markup/percent Increase for the shoe is 136.709%
2)Amount of tax on the Kyrie 5 is $4.4
3)The new price of the shoe before taxes is $35.75
Step-by-step explanation:
1) Cost price of Kyrie 5 = $55
Selling price = $130.19.
Difference = 130.19-55=75.19
So, Percentage increase =[tex]\frac{Change}{CP} \times 100[/tex]
Percentage increase =[tex]\frac{75.19}{55} \times 100 =136.709\%[/tex]
2)The state tax is 8%
So, Amount of tax on the Kyrie 5. = [tex]8\% \times 55[/tex]
=[tex]\frac{8}{100} \times 55[/tex]
= 4.4
So, You will pay $4.4 in taxes on the Kyrie 5.
3)You just found a coupon for 35% off!
New price of the shoe before taxes =[tex]55-35\%(55)[/tex]
=35.75
So,the new price of the shoe before taxes is $35.75
If you want to buy an item in a store that costs $45.50 and is on sale for 10% off, then how much would the item actually cost you after the discount? Round to the nearest cent.
Answers
Answer:
$40.95
Step-by-step explanation:
Multiply 45.50 by 0.10 and get 4.55. 4.55 is the discount. Then subtract 4.55 from 45.50 and get 40.95
Answer:
$40.95
Move the decimal over to the left once and you get 10% off the all you do is subtract that from the original cost.

Can someone help me I was doing good and then I got stuck on this question what I can’t figure out is how you get the voltage when you only have the watt and resistance .
A 60.0 Watt lightbulb has an operating resistance of 220 Ω.
Calculate the operating voltage of this lightbulb.
Answers
Answer:
114.89 V
Step-by-step explanation:
Watts are a measure of power, and there is an equation that relates power, voltage, and resistance. It goes like this:
P=(V^2)/R
Now to find the voltage you want to solve for V
PR = V^2
V = [tex]\sqrt{PR}[/tex]
Now substitute your numbers into the equation and you get your answer
V = [tex]\sqrt{(60)(220)}[/tex]
V = [tex]\sqrt{13200}[/tex]
V = 114.89 V

Four data sets are shown below.
Set 1: {10, 19, 38, 50, 513
Set 2: {5, 21, 26, 39, 51}
Set 3: {9, 38, 50, 50, 513
Set 4: {5, 28, 28, 28,513
Which data set has the largest standard deviation?
Answers
For these given four sets of data, Set: 4 has the largest standard deviation.
What is standard deviation for a data set?"Standard deviation is a measure of the amount of variation or dispersion of a set of values.
A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range."
Set: 1 {10, 19, 38, 50, 513}
Number of terms = 5
Mean = (10 + 19 + 38 + 50 + 513)/5 = 630/5 = 126
Standard deviation
= [√{(10 - 126)² + (19 - 126)² + (38 - 126)² + (50 - 126)² + (513 - 126)²}/5]
= [√(13456 + 1149 + 7744 + 5776 + 149769)/5]
= 188.62
Set: 2 {5, 21, 26, 39, 51}
Number of terms = 5
Mean = (5 + 21 + 26 + 39 + 513)/5 = 604/5 = 120.8
Standard deviation
= [√{(5 - 120.8)² + (21 - 120.8)² + (26 - 120.8)² + (39- 120.8)² + (513 - 120.8)²}/5]
= [√(11193.64 + 9960.04 + 8987.04 + 6691.24 + 153820.84)/5]
= 195.27
Set: 3 {9, 38, 50, 50, 513}
Number of terms = 5
Mean = (9 + 38 + 50 + 50 + 513)/5 = 650/5 = 130
Standard deviation
= [√{(9 - 130)² + (38 - 130)² + (50 - 130)² + (50 - 130)² + (513 - 130)²}/5]
= [√(14641 + 8464 + 6400 + 6400 + 146689)/5]
= 191.1
Set: 4 {5, 28, 28, 28,513}
Number of terms = 5
Mean = (5 + 28 + 28 + 28 + 513)/5 = 602/5 = 120.4
Standard deviation
= [√{(5 - 120.4)² + (28 - 120.4)² + (28 - 120.4)² + (28 - 120.4)² + (513 - 120.4)²}/5]
= [√(13317.16 + 8537.76 + 8537.76 + 8537.76 + 154134.76)/5]
= 196.5
Therefore, Set: 4 has the largest standard deviation.
