How do you prove that the sum of the interior angles of a convex polygon with n sides is (n-2)*180 degrees using inductive reasoning?To prove this, use mathematical induction. Base case: For a triangle (n=3), the sum is 180 degrees. Inductive step: Assume true for n=k. For n=k+1, divide the polygon into a triangle and a k-sided polygon, proving the formula holds for n=k+1. Thus, by induction, the sum of interior angles of an n-sided convex polygon is (n-2)*180 degrees.

How do you solve the equation 3x – 4 = 11?To solve the equation 3x – 4 = 11, first add 4 to both sides to get 3x = 15. Then, divide both sides by 3 to find x = 5.
How do you compute the limit of a multivariable function using L’Hopital’s Rule when approaching the origin?
How do you compute the limit of a multivariable function using L’Hopital’s Rule when approaching the origin?To compute the limit of a multivariable function using L’Hopital’s Rule when approaching the origin, first confirm the limit is in an indeterminate form. Then, apply partial derivatives to each variable iteratively, simplifying the function. Repeat until the limit can be evaluated directly.
How do you solve systems of nonlinear equations using substitution and elimination methods?
How do you solve systems of nonlinear equations using substitution and elimination methods?To solve systems of nonlinear equations using substitution, solve one equation for one variable and substitute into the other. For elimination, manipulate equations to cancel one variable. Both methods simplify the system to solve for all variables. Verify solutions by substituting back into original equations.
How do you prove that the diagonals of a parallelogram bisect each other using coordinate geometry?
How do you prove that the diagonals of a parallelogram bisect each other using coordinate geometry?To prove that the diagonals of a parallelogram bisect each other using coordinate geometry, consider a parallelogram ABCD with vertices A(x1, y1), B(x2, y2), C(x3, y3), and D(x4, y4). The midpoint of diagonal AC is ((x1+x3)/2, (y1+y3)/2) and the midpoint of diagonal BD is ((x2+x4)/2, (y2+y4)/2). Since ABCD is a parallelogram, opposite sides are equal and parallel, leading to the conclusion that these midpoints are the same, thus proving that the diagonals bisect each other.
What is the power rule for differentiation, and can you provide a simple example of how it is used?
What is the power rule for differentiation, and can you provide a simple example of how it is used?The power rule for differentiation states that if you have a function f(x) = x^n, where n is a constant, then the derivative of the function is f'(x) = nx^(n-1). For example, if f(x) = x^3, then f'(x) = 3x^2.
How do I solve the inequality 3x – 2 ≤ 7?
How do I solve the inequality 3x – 2 ≤ 7?To solve the inequality 3x – 2 ≤ 7, first add 2 to both sides to get 3x ≤ 9. Then, divide both sides by 3 to isolate x, resulting in x ≤ 3. Therefore, the solution to the inequality is x ≤ 3.
How do you solve for x in a linear equation like 2x + 5 = 15?
How do you solve for x in a linear equation like 2x + 5 = 15?To solve the linear equation 2x + 5 = 15, first subtract 5 from both sides to get 2x = 10. Then, divide both sides by 2 to isolate x, resulting in x = 5.
How do you use the Pythagorean theorem to find the unknown side length of a right triangle in a real-world problem?
How do you use the Pythagorean theorem to find the unknown side length of a right triangle in a real-world problem?To use the Pythagorean theorem in a real-world problem, identify the right triangle’s sides: the two legs (a and b) and the hypotenuse (c). Apply the formula a² + b² = c². Solve for the unknown side by rearranging the equation and taking the square root if necessary. For example, in construction, you can determine the length of a ladder needed to reach a certain height by knowing the distance from the wall.

How did the foreign policy strategies of President Woodrow Wilson impact U.S. involvement in World War I and shape the post-war peace negotiations?
Answer 1 President Woodrow Wilson's foreign policy strategies, particularly his advocacy for neutrality and later his push for a moralistic approach to international relations, initially kept the U.S. out of World War I. However, unrestricted...
What are the main implications of the separation of powers for government decision-making in the United States?
Answer 1 The separation of powers in the United States ensures that the legislative, executive, and judicial branches operate independently, providing checks and balances. This structure prevents any single branch from gaining excessive power,...
Can you explain the process and significance of electron configurations in transition metals and how it influences their chemical properties?
Answer 1 Electron configurations in transition metals involve the filling of d orbitals. This unique arrangement leads to variable oxidation states, the formation of colored compounds, and catalytic properties. The partially filled d orbitals enable...
