An object is dropped off a cliff and falls freely. It speeds up as it falls toward the ground. The graph below shows the velocity in meters per second (m/s) of the object (denoted by the vertical axis) as a function of time in seconds (denoted by the horizontal axis). Note that the relationship is linear.

This relationship is given by the equation, v = gt. In this equation, g is the acceleration due to gravity, t is the number of seconds, and v is the velocity of the falling object. Note that g is a constant.

Find and interpret the meaning of the initial value and the rate of change in this context.

The initial value is 0. That means that object’s initial velocity 0 m/s. The rate of change is 9.8. That means the acceleration due to gravity is 9.8 m/s 2.

Hope this helps :)

For the 2017-2018 school year, the average costs for one year of education is:

Tuition/Fees:   $4,391

Living Costs:   $10,406

Books/Supplies:  $1,724

Transportation:  $2,313

Other Expenses:  $3,025

With the given 7% inflation rate, the average cost will increase for the next session (2018-2019).

Hence, for year 2017-2018 the total expense will be sum of all the given costs.

= $4,391 + $10,406 + $1,724 + $2,313 + $3,025

= $21,859
