Tan(60)/cos(45) = (sin(60)/cos(60))/cos(45)
= ((√3/2)/(1/2))/(√2/2) = (√3)/(√2/2) = (2√3)/(√2)
= ((2√3)(√2))/((√2)(√2)) = (2√6)/2 = √6

Answer:
Thus to rent <u>10</u> number of videos to get the cost same.
Step-by-step explanation:
Given:
Michael's Video charges member $4 to rent each video. If you get a store membership it costs $20 and members only pay $2 to rent a video.
Now, to find the number of videos to get the cost same.
Let the number of videos to get the cost same be
Charges to rent each video without membership = $4.
Cost of membership = $20.
Charges to rent each video with membership = $2.
Now, to get the number of videos to get the cost same we write and solve an equation:
<em>Subtracting both sides by </em><em> we get:</em>
<em /><em />
<em>Dividing both sides by 2 we get:</em>
Therefore, to rent 10 number of videos to get the cost same.
Answer:
- 14 + 18i
Step-by-step explanation:
Note that i² = ( )² = - 1
Given
4i(- i + 3) - 3(6 - 21) ← distribute both parenthesis
= - 4i² + 12i - 18 + 6i
= - 4(- 1) - 18 + 18i
= 4 - 18 + 18i
= - 14 + 18i
