To find the value of x cubed (x3) when x equals 1, we start by substituting the value into the expression for x3. Given: x = 1 Now, we calculate: x3 = 13 Next, we simplify: 13 = 1 * 1 * 1 = 1 Therefore, the value of x3 when x equals 1 is: … Read more

To solve the equation 2×2 = 128, we will follow these steps: Isolate the variable: First, we need to get rid of the coefficient in front of the x2 term. We can do this by dividing both sides of the equation by 2: x2 = 64 Take the square root: Now that we have x2 … Read more

Finding the Exact Length of the Polar Curve To find the exact length of the polar curve given by the equation r = 8 + 8 cos(θ), we can use the formula for the arc length of a polar curve: L = ∫ab √(r² + (dr/dθ)²) dθ Here, r is the radius as a function … Read more

To write an expression that evaluates to true when the value of x is greater than or equal to y, you can use the following expression: x >= y Here’s a breakdown of this expression: x is the first value you’re comparing. y is the second value you’re comparing against. The operator >= is a … Read more

The cotangent of the difference of two angles, denoted as cot(a – b), can be expressed using the following formula: cot(a – b) = \frac{cot a \cdot cot b + 1}{cot b – cot a} Here’s a breakdown of the terms in the formula: cot a: This is the cotangent of angle a, which is … Read more

The ampersand symbol (&) is not commonly used in standard mathematical notation like other symbols such as +, -, *, or /. However, it does appear in various contexts and can have different meanings depending on the field or usage. 1. **Logical Operations**: In computer science and some mathematical logic contexts, the ampersand represents a … Read more

To solve the quadratic equation 6x² + 13x + 5 = 0, we can use the quadratic formula, which is given by: x = \frac{-b \pm \sqrt{b² – 4ac}}{2a} In this equation, the variables are: a = 6 b = 13 c = 5 First, we need to calculate the discriminant: b² – 4ac = … Read more

To find the median of a dataset with an odd number of observations, follow these steps: Organize the Data: Begin by sorting the dataset in ascending order. This arrangement is crucial because the median is the middle value, and you need to know the exact order of the numbers. Identify the Count: Count the total … Read more

To determine the number of solutions for the equation 12x + 34x + 2 = 0, we first need to simplify the equation: 1. Combine like terms: 12x + 34x = 46x So, the equation becomes: 46x + 2 = 0 2. Next, we will isolate the variable x. We do this by first moving … Read more

To find the measure of an angle that is equal to its complement, we need to understand what complementary angles are. Complementary angles are two angles whose measures add up to 90 degrees. Let’s denote the angle we are trying to find as x. According to the definition of complementary angles, the complement of x … Read more
