Answer:
A' = { 2,4,6,8,10,12,14,16,17,18,19}
A' U B = {2,4,6,8,10,12,14,16,17,18,19,7,11,13}
Step-by-step explanation:
A = {1,3,5,7,9,11,13,15}
B = {7,11,13,17,19}
<u><em>To</em><em> </em><em>find</em><em> </em><em>:</em><em> </em></u>

<em>Now</em><em> </em><em>divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>,</em><em> </em>
<em>So</em><em> </em><em>,</em><em> </em><em>we</em><em> </em><em>got</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em> </em>

figure 1, 2 respectively
62.5 Answer
5
x^2-7x=30
x^2-7x-30=0
a = 1, b = -7, c = -30
sqrt(b^2-4ac)
sqrt(49+120)
sqrt(169)
13
-b +/- 13
7 + 13 = 20
7 - 13 = -6
2a = 2
20/2 = 10
-6/2 = -3
we know x>0, so it cant be -3. so now its just 10 - 5
When the input is 6, the output must be 12.
f(6) = 12
The input to the function is x which is 6 and the output is what f(6) equals which is 12
1/360
Since there are 360 degrees in a circle, a single one of these would mean that the angle turns through 1/360th of a circle. Hope this helps!
