A calculus teacher likes to give questions at various point in every class to see if student can apply what they have learned up to that time; she needs to see students’ answers immediately, so she can give timely remedial help, if needed. Which software package would be the best suited for such a task?

Educational software such as the Assessment software.

Step-by-step explanation:

The assessment software is an educational software that allows students to be assessed with the use of information technology devices such as the Computer.

Assessment Master is one of the most popular assessment softwares available. It is an online platform with great flexibility as assessment can be conducted from any location. There is a provision for automated marking.

The calculus teacher could use this assessment software for her students. When the questions are administered, the students type in their answers and with the aid of the automated marking, the teacher evaluates them and offers remedial help.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
