Answer:
1 + cosa sina
Step-by-step explanation:
cos³a - sin³a ← is a difference of cubes and factors in general as
a³ - b³ = (a - b)(a² + ab + b²) , then
cos³a - sin³a
= (cosa - sina )(cos²a + cosa sina + sin²a)
= (cosa - sina)(1 + cosa sina) [ sin²a + cos²a = 1 ]
Then
= 
← cancel (cosa - sina) on numerator/ denominator
= 1 + cosa sina
Mark Achin's economic order quantity in units is <u>D. 120 units</u>.
<h3>What is economic order quantity?</h3>
The economic order quantity (EOQ) is the optimal order quantity that minimizes the total costs (ordering, receiving, and holding inventory).
The formula for the economic order quantity is the square root of [2(setup costs)(demand rate)] / holding costs.
<h3>Data and Calculations:</h3>
Annual demand = 3,600
Cost price per unit = $200
Ordering cost = $40
Holding cost per unit = $20
Working days per year = 360
Lead time = 5 days
Economic order quantity (EOQ) = square root of: [2(setup costs)(demand rate)] / holding costs.
= square root of (2 x $40 x 3,600)/$20
= 120
Thus, Mark Achin's economic order quantity in units is <u>D. 120 units</u>.

38 degrees.
EXPLANATION
There are 2 angles.
The angles must add up to 180.
So taking 180 and subtracting the already known angle, of 142.
Will get us with 38.
We can check the work by doing 38 + 142.
Hope this helps! have a gud day
