Answer:
Step-by-step explanation:
It asks for the common set of A and B.
<u>There only one element common to both the given sets:</u>
- A={2,3,5,7} and B={2,4,6,8} ⇒ A∩B = {2}
For a parallelogram, the parallel sides must be the same length. This means you can set their lengths equal to each other. Get like terms on the same side to calculate x.
3x-5=2x+3
3x-5+5=2x+3+5
3x=2x+8
3x-2x=2x-2x+8
x=8
x=8

Step-by-step explanation:
e = 20sin(πt/4 - π/2)
= 20[(sinπt/4)(cosπ/2) - (cosπt/4)(sinπ/2)]
Used sin(x - y) = sinxcosy - cosxsiny.
= 20[0 - cosπt/4]
Since cosπ/2 = 0 and sinπ/2 = 1.
= -20cosπt/4.
