how do i estimate the area under the graph of f(x) = 2 cos(x) from x=0 to x= T / 2 using four approximate rectangles and right endpoints . how would i round it to 4 decimal places? And how would the graph with the shaded rectangles look like ? would it be an overestimate? the last person gave me an AI answer but i need a written paper to understand. please show me what the graph exactly looks like. thank you so much

The kinetic energy E of an object varies jointly with the object’s mass m and the square of the object’s velocity v . An object with a mass of 50 kilograms traveling at 16 meters per second has a kinetic energy of 6400 joules. What is the kinetic energy of an object with a mass of 70 kilograms traveling at 20 meters per second?

The number of research article in the prominent journal Physical Review that were written by researchers in Europe during 1983 - 2003 can be modeled by P(t) = 7.0/ (1 + 5.4(1.2)^−t) where t is time in years since 1983. The graphs of P, P', and P" are shown below. Determine, to the nearest whole number, the value of t for which the graph of P is concave up and where it is concave down, and locate any points of inflection. Explain your methods thoroughly, including how the inflection point of f can be determined with each of the three graphs, some more clearly than others. What does the point of inflection tell you about scientific articles?
