What is the standard form of the equation of the circle?

The standard form of the equation of a circle is expressed as: (x – h)² + (y – k)² = r² In this equation: (h, k) represents the center of the circle. r represents the radius of the circle. To break it down further, the expression (x – h)² + (y – k)² shows the […]

Find the derivative of the given function sin(3x^5)

To find the derivative of the function sin(3×5), we will use the chain rule. The chain rule states that the derivative of a composite function f(g(x)) is f'(g(x)) * g'(x). In our case, let: u = 3×5 f(u) = sin(u) Now, we need to find the derivatives of f(u) and u: f'(u) = cos(u) u’ […]

How many degrees would the hour hand move in 4 hours?

The hour hand of a clock completes one full revolution, which is 360 degrees, in 12 hours. To determine how much the hour hand moves in 4 hours, we can use the following calculation: First, we find out how many degrees the hour hand moves per hour: Degrees per hour: 360 degrees / 12 hours […]

How to Solve the Equation 3x² + 2x + 7 = 0?

To solve the quadratic equation 3x² + 2x + 7 = 0, we can use the quadratic formula, which is given by: x = (-b ± √(b² – 4ac)) / 2a In our equation, a = 3, b = 2, and c = 7. First, we need to calculate the discriminant, which is b² – […]

Find the sum of 3 + 7i and 8 + 4i

To find the sum of the complex numbers 3 + 7i and 8 + 4i, we will add the real parts together and the imaginary parts together. The real parts are: 3 8 Adding these together gives us: 3 + 8 = 11 Next, we’ll add the imaginary parts: 7i 4i Adding these gives us: […]

How to Calculate the Loss on Selling Shares of Stock?

To calculate the loss on selling shares of stock, you need to know the original purchase price per share, the selling price per share, and the number of shares sold. In this case, the original purchase price was 13 3/4 (which is the same as 13.75) and the selling price was 12. We sold 50 […]
