devyy To find the number of sides (n) in a polygon when given the sum of its angle measures, we can use the following formula: Sum of interior angles = (n – 2) × 180 In this case, we’re told that the sum of the angle measures is 2880 degrees. So we can set up the … Read more
To find two unit vectors that are orthogonal to both vectors (3, 2, 1) and (1, 1, 0), we can follow these steps: Step 1: Find the Cross Product The first step is to find a vector that is orthogonal to both given vectors. This can be done using the cross product. For two vectors … Read more
In geometry, adjacent angles are defined as two angles that share a common side and a common vertex, yet do not overlap. To determine which pairs of angles are adjacent, you need to look closely at their positions and relationships. Consider the following pairs of angles: Angle A and Angle B Angle C and Angle … Read more
To solve the quadratic equation x² + 4x – 18 = 0, we can use the quadratic formula, which is given by: x = (-b ± √(b² – 4ac)) / 2a In our equation, we can identify the coefficients as follows: a = 1 (the coefficient of x²) b = 4 (the coefficient of x) … Read more
To solve the equations for x and y, we start with the given equation: 7y + 3 = 2x^2 + 14 + 4y – 2 + 3x. First, we need to simplify the equation. Reorganizing terms, we get: 1. Move all terms involving y to one side and those involving x to the other side: … Read more
To find the greatest number that can be formed using the digits 5, 3, 1, 4, and 7, we need to arrange these digits in descending order. The descending order means we start with the largest digit and proceed to the smallest. Here are the digits in the set: 5 3 1 4 7 Arranging … Read more
To solve the equation x2 + 4x + 5 = 0 by graphing, you’ll first need to understand the process of converting the quadratic equation into a function that can be plotted.

The quadratic formula is a useful tool for finding the solutions to any quadratic equation of the form ax² + bx + c = 0. The formula is: x = (-b ± √(b² – 4ac)) / (2a) In this case, your equation is: x² – 2x – 20 = 0 Here, we can identify the … Read more
The present value (PV) of an amount of money is calculated using the following expression: PV = FV / (1 + r)^n Where: PV: Present Value – the current worth of a given amount of money in the future. FV: Future Value – the amount of money you expect to receive in the future. r: … Read more
To determine the x-intercept of the line given by the equation 6x + 2y = 18, we follow a straightforward process. The x-intercept is the point where the line crosses the x-axis, which occurs when the value of y is zero. Here are the steps to find the x-intercept: Set y = 0 in the … Read more
