devyy A factor tree is a visual representation that shows how a particular number can be expressed as a product of its prime factors. For the number 60, we can generate two distinct factor trees. Factor Tree 1 1. Start with the number 60 at the top. 2. The first step is to divide 60 by … Read more
To find the zeros of the function f(x) = x² + 2x + 3, we need to determine the values of x that make the equation equal to zero. In mathematical terms, we set the function equal to zero: x² + 2x + 3 = 0 This is a quadratic equation, and we can find … Read more
The symbol for ‘less than or equal to’ is represented as ‘≤’. This mathematical symbol is widely used in various fields, including mathematics, computer science, and economics, to compare two values. It indicates that one value is either less than or exactly equal to another value. For example, in the statement ‘x ≤ 10’, it … Read more
The total number of different permutations of a set can be calculated using the factorial of the number of elements in that set. For the set {a, b, c, d, e, f, g}, there are 7 distinct elements. The formula for calculating permutations is represented as n!, where n is the number of elements in … Read more
The radius of the Earth is approximately 6380 kilometers. To convert this measurement into centimeters, we need to recognize that 1 kilometer is equal to 100,000 centimeters. Therefore, to convert kilometers into centimeters, we can use the following calculation: Take the radius in kilometers: 6380 km Multiply by the number of centimeters in a kilometer: … Read more
To simplify the expression i^(233) * (1 + i), let’s break it down into parts. Understanding the Powers of i The imaginary unit i is defined as the square root of -1. The powers of i follow a cyclic pattern: i^1 = i i^2 = -1 i^3 = -i i^4 = 1 This cycle repeats … Read more
The given sequence is 3, 6, 12, 24. To find the 12th term, we first need to identify the pattern in the sequence. Looking at the sequence, we can observe the following: The first term is 3. The second term (6) is obtained by multiplying the first term (3) by 2. The third term (12) … Read more
To find the ordered pairs that solve the equation 2xy = 9, we first need to express one variable in terms of the other. Let’s solve for y. Starting with the equation: 2xy = 9 We can isolate y by dividing both sides by 2x (assuming x is not zero): y = 9 / (2x) … Read more
To find the slope of a line that is perpendicular to another line, we can use a simple rule from geometry regarding slopes. If the slope of the original line is denoted as m, then the slope of a line that is perpendicular (at a right angle) to it is given by the negative reciprocal … Read more
To determine if a number is divisible by 3, you can follow a couple of simple methods that are easy to use and understand. Here’s a detailed explanation of these methods: 1. The Rule of Sum of Digits The most common method to check for divisibility by 3 is to add up all the digits … Read more
