To determine the values of r for which the function y = erx satisfies the differential equation 2yy’ = y, we first need to differentiate the function with respect to x. The function y = erx is an exponential function, where e is the base of the natural logarithm. The derivative of y with respect … Read more
To determine how many notepads can fit in a box that is 2 feet wide, we first need to convert the width of the box from feet to inches, since the width of the notepad is given in inches. Since there are 12 inches in a foot, we can calculate the width of the box … Read more
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
