The graph represents the rate of two machines that fill water barrels. one machine has already filled 30 water barrels before
the faster machine starts. according to the graph, about how many minutes will pass before the two machines have filled about
the same number of barrels?

a. 5 minutes
b. 30 minutes
c. 45 minutes
d. 50 minutes

5. illustrate how fine-line inventory classification can be used with product and market segments. what are the benefits and considerations when classifying inventory by product, market, and product/market?

Consider the following statements: struct nametype{string first; string last; }; struct coursetype{string name; int callnum; int credits; char grade; }; struct studenttype{nametype name; double gpa; coursetype course; }; studenttype student; studenttype classlist[100]; coursetype course; nametype name; mark the following statements as valid or invalid. if a statement is invalid, explain why.a.) student.course.callnum = "csc230"; b.) cin > > student.name; c.) classlist[0] = name; d.) classlist[1].gpa = 3.45; e.) name = classlist[15].name; f.) student.name = name; g.) cout < < classlist[10] < < endl; h.) for (int j = 0; j < 100; j++)classlist[j].name = name; i.) classlist.course.credits = 3; j.) course = studenttype.course;

Consider the series where in this problem you must attempt to use the ratio test to decide whether the series converges. compute enter the numerical value of the limit l if it converges, inf if it diverges to infinity, minf if it diverges to negative infinity, or div if it diverges but not to infinity or negative infinity.
