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}

Answer:
(x-9)^2 +(y-12)^2 = 225
Step-by-step explanation:
First find the length of the radius
If is the distance from the center to the point
d = sqrt( (x2-x1)^2 + (y2-y1)^2 )
= sqrt( (0-9)^2 + (0-12)^2)
= sqrt ( 81+144)
= sqrt(225)
= 15
The equation for a circle is
( x-h) ^2+ (y-k)^2 = r^2
(x-9)^2 +(y-12)^2 = 15^2
(x-9)^2 +(y-12)^2 = 225
Answer:
80%
Step-by-step explanation:
There are 4 shaded sections and 1 unshaded section, so five sections in total.
4 sections are shaded, so the fraction would be 4/5.
Dividing 4/5 gets you 0.8, move the decimal point two places over to get the percent (80%).
The density is 0.1019g/cm3
