How to derive the vertex form of a quadratic equationIn this problem we find ten cases of quadratic equation in standard form, whose vertex form can be found by a combination of algebra properties known as completing the square. Completing the square consists in simplifying a part of the quadratic equation into a power of a binomial.
The two forms are introduced below:
Standard form
y = a · x² + b · x + c
Where a, b, c are real coefficients.
Vertex form
y - k = C · (x - h)²
Where:
C - Vertex constant(h, k) - Vertex coordinates.Now we proceed to determine the vertex form of each quadratic equation:
Case 9
y = 2 · x² + 4 · x - 4
y = 2 · (x² + 2 · x - 2)
y = 2 · (x² + 2 · x + 4) - 12
y = 2 · (x + 2)² - 12
Case 10
y = - (1 / 2) · x² - 3 · x + 3
y = - (1 / 2) · [x² + (3 / 2) · x - 3 / 2]
y = - (1 / 2) · [x² + (3 / 2) · x + 9 / 16] + (1 / 2) · (33 / 16)
y = - (1 / 2) · (x + 3 / 4)² + 33 / 32
Case 11
y = 3 · x² - 8 · x
y = 3 · [x² - (8 / 3) · x]
y = 3 · [x² - (8 / 3) · x + 16 / 9] - 3 · (16 / 9)
y = 3 · (x - 4 / 3)² - 16 / 3
Case 12
y = - 3 · x² + 18 · x - 27
y = - 3 · (x² - 6 · x + 9)
y = - 3 · (x - 3)²
Case 13
y = x² - 8 · x + 19
y = (x² - 8 · x + 16) + 3
y = (x - 4)² + 3
Case 14
y = x² - 2 · x - 6
y = (x² - 2 · x + 1) - 7
y = (x - 1)² - 7
Case 15
y = x² + 3 · x
y = (x² + 3 · x + 9 / 4) - 9 / 4
y = (x + 3 / 2)² - 9 / 4
Case 16
y = 2 · x² + x
y = 2 · [x² + (1 / 2) · x]
y = 2 · [x² + (1 / 2) · x + 1 / 16] - 2 · (1 / 16)
y = 2 · (x + 1 / 4)² - 1 / 8
Case 17
y = 2 · x² - 12 · x + 11
y = 2 · (x² - 6 · x + 9) - 2 · (7 / 2)
y = 2 · (x - 3)² - 7
Case 18
y = - 2 · x² - 4 · x + 8
y = - 2 · (x² + 2 · x - 4)
y = - 2 · (x² + 2 · x + 1) + 2 · 5
y = - 2 · (x + 1)² + 10

Can you solve this question?
a) find the derivative=?
b) find the derivative=?
Answers
A. the derivative of y = log_a(x) is: y' = log_a(x) / (x ln(a))
B. the derivative of y = log_8(x) is: y' = 1 / (x ln(8 ln(10)))
a) Using the chain rule and the given identity, we have:
y = log_a(x)
ln(y) = ln(log_a(x))
ln(y) = ln(x) / ln(a)
y' / y = 1 / (x ln(a))
Multiplying both sides by y and simplifying, we get:
y' = y / (x ln(a))
y' = log_a(x) / (x ln(a))
Therefore, the derivative of y = log_a(x) is: y' = log_a(x) / (x ln(a))
b) Using the change of base formula for logarithms, we have:
y = log_8(x)
y = log(x) / log(8)
Using the chain rule, we have:
y' = (1 / (x ln(10))) * (1 / ln(8)) * d/dx [log(x)]
Using the chain rule for the natural logarithm, we have:
y' = (1 / (x ln(10))) * (1 / ln(8)) * (1/x)
Simplifying, we get:
y' = 1 / (x ln(8 ln(10)))
Therefore, the derivative of y = log_8(x) is:
y' = 1 / (x ln(8 ln(10)))

Jacque is using a soup can for a school project and wants to paint it. If the can is 11 cm tall and has a diameter of 9 cm, at least how many square centimeters of paint is needed? Approximate using π = 3.14.
374.45 cm2
139.50 cm2
699.44 cm2
438.03 cm2
Answers
Answer:
The surface area of the soup can is given by the formula:
SA = 2πr² + 2πrh
where r is the radius of the circular ends of the can, h is the height of the can, and π is approximately 3.14.
The radius of the can is half of the diameter, so r = 4.5 cm.
Therefore, the surface area of the can is:
SA = 2π(4.5)² + 2π(4.5)(11)
SA = 2π(20.25) + 2π(49.5)
SA = 40.5π + 99π
SA = 139.5π
Approximating π as 3.14, we get:
SA ≈ 139.5 × 3.14
SA ≈ 438.03 cm²
Therefore, at least 438.03 square centimeters of paint are needed to cover the can.
So, the answer is 438.03 cm2.

Solve for the tangent line of cos(x) at x= pi/4. Use the tangent line to estimate the value of cos(48).
Answers
The estimated value of cos(48) by using tangent line is found to be
0.99989.
Explain about the tangent line ?A straight line which thus touches a function only once is called a tangent line.
The first step is to calculate y when x=π/4. We will receive that target coordinate point as a result.
The required coordinate point is ( π/ 4, √(2) / 2)
The derivative of such function y is then discovered.
y ' = -sin(x)
Input the derivative with the value of x. This corresponds to the tangent line's slope.
y' = -sin(π/4)
y' = - √(2) / 2
The slope plus coordinate point are now entered into the gradient intercept form of the formula to obtain b.
y = mx + b
√(2) / 2 = (-√(2) / 2)(π / 4) + b
√(2) / 2 = (-π√(2) / 8) + b
(√(2) / 2) + (π√(2) / 8) = b
[4√(2) + π√(2)] / 8 = b
[(4 + π)√(2)] / 8 = b
The tangent line comes out to be:
y = (-√(2) / 2)x + [(4 + π)√(2) / 8]
Now , for cos(48).
48° = π/180 * 48 radians
48° = 3.14/180 * 48 radians
48° = 0.01744*48 radians
48° = 0.83712 radians
So, cos(48) = cos( 0.83712 )
Using scientific calculator:
cos(48) = cos( 0.83712 ) = 0.99989
Thus, the estimated value of cos(48) by using tangent line is found to be
0.99989.

Find the value of x. Then tell whether the side lengths for a pythagorean triple
Answers
The value of x, given the measurements of the other sides of the triangle, would be 8.
The side lengths of the triangle form a Pythagorean triple.
How to find the value of x in the triangle ?To determine if the side lengths form a Pythagorean triple, we need to apply the Pythagorean theorem.
Using the Pythagorean theorem, we get:
6^2 + x^2 = 10^2
36 + x^2 = 100
x^2 = 100 - 36
x^2 = 64
x = 8
To determine if the side lengths form a Pythagorean triple, we need to check if the Pythagorean theorem holds true. Plugging in the values, we get:
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100

Determine whether the statement is always true, sometimes true, or never true. Give examples. Both sides of an equation can be multiplied by the same number without changing the solution of the equation. A number can be added to both sides of an equation changing the solution of the equation.
Answers
The solution of the equation is x = 2. If we had multiplied both sides by a different number, such as 3 or -4.
What is solution of the equation ?
The solution of an equation is the value(s) of the variable(s) that make the equation a true statement. In other words, it is the value(s) that satisfy the equation.
For example, consider the equation 3x + 4 = 13. To find the solution, we need to determine the value of x that makes the equation true. the solution of the equation 3x + 4 = 13 is x = 3.
According to the question:
The first statement, "Both sides of an equation can be multiplied by the same number without changing the solution of the equation" is always true.
Example: Consider the equation 3x = 6. If we multiply both sides of this equation by 2, we get:
2 * 3x = 2 * 6
6x = 12
The solution of the equation is x = 2. If we had multiplied both sides by a different number, such as 3 or -4, we would still get the same solution.
The second statement, "A number can be added to both sides of an equation changing the solution of the equation" is sometimes true.
Example: Consider the equation 2x = 4. If we add 3 to both sides of the equation, we get:
2x + 3 = 4 + 3
2x + 3 = 7
The solution of the equation is x = 2.5. Adding 3 to both sides did not change the solution.
However, if we add a number that is equal to or related to the variable, the solution will change. For example, if we add x to both sides of the equation 2x = 4, we get:
2x + x = 4 + x
3x = 4 + x
The solution of the equation is x = 4/2 = 2, which is different from the previous solution of x = 2. Therefore, the statement "A number can be added to both sides of an equation changing the solution of the equation" is sometimes true, depending on the number being added.

Assuming that the 75 feet measurement is the distance from where Justin is at the ground level to the fish (and not the diagonal distance from his location to the fish), the angle is given by arctan(28/75) = 28.472 degrees. This is probably the right answer.
If the 75 feet measurement is the diagonal distance, the angle is arcsin(28/75) = 21.921 degrees.

You are paid 1.5 times your normal hourly rate for each hour you work over 32 hours in a week. You work 33 hours this week and earn 545.38 . What is your normal hourly rate?
Answers
The normal hourly rate is 16.28 units
What is unit rate?
A unit rate is the cost for only one of anything. This is expressed as a ratio with a denominator of 1. For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.
Let r be your rate you get paid per hour normally.
Total = 33 hours
Extra hour = 33 -32 = 1 hour
We have
32r + 1.5r = 545.38
=> 33.5r = 545.38
=> r = 545.38 /33.5 = 16.28

FV = $600(1 + 0.075 x 5)
FV = $825
Balance of the second account with compounded interest:
FV = P(1 + r)^n
FV = $900(1 + 0.06)^5
FV = $1,286.87
Total balance = $825 + $1,286.87

Answers
This report highlights the impact of human activity on three different locations: New York City, the Amazon Rainforest, and the Sahara Desert. The measurements were taken 50 years ago, in the present day, and the predicted future development impact.
## New York City
Water pollution in parts per million (ppm) was measured in New York City. Fifty years ago, the water pollution was 625ppm, and presently, it has increased to 893ppm. The predicted future development impact is 843ppm. To decrease human impact on this location, it is recommended to create gardens on all of the rooftops. The plants will help absorb some of the pollutants and reduce runoff into waterways.
## Amazon Rainforest
CO2 levels in parts per million (ppm) were measured in the Amazon Rainforest. Fifty years ago, the CO2 levels were 318ppm, and presently, it has increased to 402ppm. The predicted future development impact is 378ppm. To decrease human impact on this location, it is recommended to limit the amount of timber that can be removed per year. The Amazon Rainforest is often referred to as the "lungs of the planet" due to its ability to absorb carbon dioxide and produce oxygen. By limiting deforestation, the amount of carbon dioxide released into the atmosphere will decrease, and the rainforest will continue to produce oxygen, benefiting both the local and global environment.
## Sahara Desert
The loss of land by erosion in meters was measured in the Sahara Desert. Fifty years ago, the erosion was 1.2 meters, and presently, it has increased to 3.5 meters. The predicted future development impact is 2.6 meters. To decrease human impact on this location, it is recommended to build better enclosures to decrease overgrazing by livestock. Overgrazing leads to soil compaction, which makes it difficult for vegetation to grow and prevents the soil from holding water. By implementing better enclosures, the livestock will be limited to a smaller area, allowing the vegetation to recover and hold the soil in place.
## Conclusion
In conclusion, all three locations experienced an increase in human impact over the years. By analyzing the data, the location that could benefit the most from decreasing human impact is the Amazon Rainforest. Limiting the amount of timber that can be removed per year will have a positive impact on this location. However, it is important to continue monitoring all three locations to ensure that the human impact is decreasing and not increasing.
## Recommendations for Local Communities
To decrease the local effects of human impact on the environment, two recommendations are:
1. Reduce the use of single-use plastics, such as straws and bags, to decrease pollution. Single-use plastics are a major source of pollution in our oceans, and by reducing our reliance on them, we can help reduce the amount of plastic that ends up in our waterways.
2. Plant more trees and vegetation to increase the amount of oxygen in the air. Trees and plants produce oxygen through photosynthesis, which helps clean the air we breathe. By planting more trees and vegetation in our communities, we can help reduce the amount of pollution in the air and create a healthier environment for ourselves and future generations.
## Recommendations for Global Governments
To decrease the global effects of human impact on the environment, two recommendations are:
1. Invest in renewable energy sources, such as solar and wind power, to decrease the use of fossil fuels. Fossil fuels are a major contributor to greenhouse gas emissions, which are responsible for climate change. By investing in renewable energy sources, we can decrease our reliance on fossil fuels and reduce our carbon footprint.
2. Implement policies to decrease deforestation and promote reforestation to decrease the loss of wildlife habitats and increase the amount of oxygen in the air. Deforestation is a major contributor to climate change, as it releases carbon dioxide into the atmosphere and reduces the amount of oxygen produced by trees. By implementing policies to decrease deforestation and promote reforestation, we can help mitigate the effects of climate change and create a healthier environment for all living beings.

I have a barn that is a regular hexagon, as shown. Each side of the barn is 100 feet long. I tether my burro to point A with a 150 foot rope. Find the area of the region in which my burro can graze. Round your answer to nearest foot squared.
Answers
The area of the region in which the burro can graze will be 833 pi square feet.
What is the value of the area?Each interior vertex angle of a regular hexagon is (n - 2)·180°/n = (6 - 2)·180°o/6 = 120°
I'll break up the area into three sections.
There is one major section, going 150' along one side in a circular arc to 150' along the adjacent side.
Since the interior angle is 120°, the exterior angle will be 240°.
The area of this section will be: (240°/360°)·pi·radius2 = (2/3)·pi·1502 = 15,000 pi
Then, on each end, around the corner of the barn, the goat can go in a circular arc with radius = 50'.
This angle will be 60°, or one-sixth or a circle.
The area of each section will be (1/6)·pi·502 = 416 2/3 pi
Total area: 15,000 pi + 416 2/3 pi + 416 2/3 pi = 833 1/3 pi square feet.
