The derivative of the function f is given by f'(x) = x 3 - 4 sin(x 2) + 1.If the initial temperature of the tea, at time t = 0 minutes, is 200 °F and the temperature of the tea changes at the rate R(t) = -6.89e -0.053t degrees Fahrenheit per minute, what is the temperature, to the nearest degree, of the tea after 4 minutes? A cup of tea is cooling in a room that has a constant temperature of 70 degrees Fahrenheit.If s is increasing for 0 ≤ t 2, which of the following is the total distance the particle travels for 0 ≤ t ≤ 5? For time t > 0, the position of a particle traveling along a line is given by a differentiable function s.If f(0) = 0, which of the following could be the graph of f ? The figure above shows the graph of f', the derivative of the function f.
The graph of the function f shown above consists of two line segments and a semicircle.
