devyy At 270 degrees, which is equivalent to 3π/2 radians, we can determine the values of the six primary trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent. 1. Sine Function The sine of 270 degrees is given by: sin(270°) = -1 2. Cosine Function The cosine of 270 degrees is: cos(270°) = 0 3. Tangent … Read more
To find an expression equivalent to 2x² + 2x + 7, we can analyze the polynomial and look for ways to factor or rewrite it. Firstly, let’s rewrite the given expression clearly: 2x² + 2x + 7 We can see that this is a quadratic polynomial in the format of ax² + bx + c, … Read more
To determine the open intervals on which a function is increasing by examining its graph, follow these steps: Understand the Graph: Start by looking at the graph of the function. An increasing function is characterized by a slope that moves upward as you move from left to right. This means that for any two points … Read more

To find the value of 20 divided by 10, you can use the basic principle of division, which essentially asks how many times does 10 fit into 20. The calculation is straightforward: you divide 20 by 10, which you can write as: 20 ÷ 10 Now, performing the division: 20 ÷ 10 = 2 This … Read more
To convert the improper fraction 31/6 into a mixed number, you need to follow a few simple steps: Divide the numerator by the denominator: Divide 31 by 6. When you do this, you find that 31 ÷ 6 = 5 with a remainder of 1. Write down the whole number: The result of the division … Read more
When we talk about 4 raised to the power of 2, we’re actually referring to a mathematical operation known as exponentiation. In this case, 4 is the base and 2 is the exponent. This means that we multiply the base (4) by itself as many times as indicated by the exponent (2). So, calculating 4 … Read more
To find five percent of five thousand, you can use a simple calculation method. Here’s how it works: First, convert the percentage to a decimal. Five percent (5%) can be written as 0.05. Next, multiply the decimal by the total number. So, you take 0.05 and multiply it by 5000: 0.05 x 5000 = 250 … Read more
Understanding the difference between an outcome and an event is crucial across various fields, including statistics, project management, and everyday life. An event refers to a specific occurrence or happening. It can be something that takes place at a particular point in time and can often be observed or measured. For example, in the world … Read more
A ray in geometry is a part of a line that has a fixed starting point but extends infinitely in one direction. It’s like the sun’s rays spreading out from the sun; they begin at one point but continue on without ever ending. To understand rays better, here are some key features: Starting Point: A … Read more
