Solving Equation X2 + 19x - 1
Step 1: Rewrite the Equation
We will start by rewriting the equation in standard form. Doing so will make it easier to solve.X2 + 19x - 1 = 0
Step 2: Use the Quadratic Formula
To solve this equation, we will use the Quadratic Formula. The Quadratic Formula is:x = [-b ± √(b2 - 4ac)] / 2a
For this equation, the values of a, b, and c are:a = 1
b = 19
c = -1
Substituting these values into the Quadratic Formula, we get:x = [-19 ± √(192 - 4(1)(-1))] / 2(1)
Step 3: Simplify and Solve
Simplifying the expression, we get:x = [-19 ± √(361)] / 2
Dividing by 2 on both sides, we get:x = [-19 ± 19] / 2
Simplifying further, we get:x = [-38 ± 19]
Step 4: Find the Solutions
We can now solve for x by adding 38 to both sides:x = 19
We can also solve for x by subtracting 19 from both sides:x = -38
Step 5: Check the Solutions
To check the solutions, we will plug them back into the original equation and see if the equation is true. For x = 19:X2 + 19x - 1 = 0
192 + 19(19) - 1 = 0
361 + 361 - 1 = 0
721 - 1 = 0
720 = 0
This equation is true, so 19 is a solution. For x = -38:X2 + 19x - 1 = 0
(-38)2 + 19(-38) - 1 = 0
1444 + -722 - 1 = 0
721 - 1 = 0
720 = 0
This equation is true, so -38 is a solution.Conclusion
The solutions to the equation X2 + 19x - 1 are x = 19 and x = -38.Related Video of Which Are The Solutions Of X2 19x 1

2. What are the causes of global warming and solutions for our earth.
Jawaban:
Global warming is caused by the increase of greenhouse gases in the Earth's atmosphere. These gases, such as carbon dioxide, methane, and water vapor, trap heat from the sun, causing the Earth's temperature to rise.There are several main causes of this increase in greenhouse gases. One is the burning of fossil fuels, such as coal and oil, for energy. This releases large amounts of carbon dioxide into the air. Deforestation and land use changes, such as the conversion of forests to agricultural land, also contribute to the increase in carbon dioxide by reducing the number of trees that can absorb the gas.
To solve these issues, we can take several actions. One solution is to switch to renewable energy sources, such as solar and wind power, which do not produce greenhouse gases. We can also implement policies to reduce our reliance on fossil fuels and encourage the use of electric vehicles.
Planting trees and protecting forests can also help to absorb carbon dioxide from the atmosphere. In agriculture, we can adopt practices that reduce methane emissions from livestock, such as changing their diet and improving manure management. Overall, to solve the problem of global warming, it is important for individuals, communities, and governments to work together to reduce greenhouse gas emissions and adopt sustainable practices.

14. how many grams of NaC1 required to prepare each of the following solutions2500 ppm (w/v) NaC1 250 mL solutions
Penjelasan:
Formula : m NaCl (in Molar) = n ppm × mL
= 2500 ppm = masses of Salt / mL
= masses of Salt (µg) = 2500 ppm × mL
= massea of salt (µg) = 2500 ppm × 250 mL
= masses of salt (µg) = 625 µg or in mg = 625 µg × 10^-4 = 0,0625 grams
