The set of ordered pairs a where t is the time in seconds after
someone jumps out of a plane at
4000 meters to go skydiving, and d
is the displacement above the
ground

I need to find the domain and Range.

Domain is and range is [0,4000].

Step-by-step explanation:

It is given that, the set of ordered pairs (t,d), where

t = the time in seconds after  someone jumps out of a plane at  4000 meters to go skydiving

d = is the displacement above the  ground.

It means t is independent variable and it is represented on the x-axis.

d is dependent variable and it is represented on the y-axis.

We need to find the domain and Range.

Domain is the set of input values.

Here, input is time and time can not be negative.

Domain

Range is the set of output values.

Here, output is displacement above the  ground which can not be negative or more than 4000 meters.

Range

Therefore, domain is and range is [0,4000].

sorry not sure

step-by-step explanation:

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
