Answer:
AUB={1,2,4,5,7,9}
ANB={ }
Explanation:
AUB means that you have to combine all the element in each set whereas ANB is the set of similar elements in set A and set B. As there is no same elements in set A and set B therefore ANB will be called as null set.
Answer:
45 J
Explanation:
Work done = force × displacement
(<em>displacement</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>shortest</em><em> </em><em>distance</em><em> </em><em>the</em><em> </em><em>object</em><em> </em><em>travels</em><em> </em><em>when</em><em> </em><em>a</em><em> </em><em>force</em><em> </em><em>is</em><em> </em><em>applied</em><em> </em><em>on</em><em> </em><em>it</em><em>)</em>
W = 15 × 3
= 45 J
[Note: While using the formulae, all quantities must be in their SI units.]
Since you already have the equation, all you need to do is pick two values of x.
For example, when x = 0, you get y = 7/4(0) + 2 = 2. So the line passes through the point (0, 2). When x = 4 (picked to cancel the 4 in the fraction), you get y = 7/4(4) + 2 = 9, so the line also passes through the point (4, 9).
You can describe an entire line by any two points that it contains. So plot these two points, then connect the dots with a line passing through them both.
