Answer:
See the proof below.
Step-by-step explanation:
For this case we need to proof the following indentity:
So we need to begin with the definition of tangent, we know that 
and we can do this:
(1)
We also have the following identities:
Now we can apply those identities into equation (1) like this:
(2)
We can divide numerator and denominator from expression (2) by 
we got this:
And simplifying we got:
And that complete the proof.
Dulari can deduct $3050 as moving expenses for her 2020 return
Pre-housing cost = $1475
Cost of the moving furniture = $2500
Cost of moving personal belongings = $3475
Total cost incurred while at Washington DC = $1475 + $2500 + $3475
Total cost incurred = $7450
AGI for 8 years = $84500
AGI for 1 year = $84000/8
AGI for 1 year = $10500
Since Dulari already spent $7450 trying to settle in Washington, she will spend ($10500 - $7450) as moving expenses for her return
$10500 - $7450 = $3050
Dulari can deduct $3050 as moving expenses for her 2020 return

Answer:
A sample space is a collection or a set of possible outcomes of a random experiment. The sample space is represented using the symbol, “S”. The subset of possible outcomes of an experiment is called events. A sample space may contain a number of outcomes that depends on the experiment
