Boyle’s law states that if the temperature of an ideal gas is held constant, then the pressure P of the gas and its volume V satisfy the relationship P=k/V , where k is a constant. Which of the following best describes the relationship between the rate of change, with respect to time t , of the pressure and the rate of change, with respect to time t , of the volume?

Which expression is equivalent to the expression shown?

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
