For the set c={3,5}, determine n(c) n(c)=

2

The notation n(C) translates to "the number of items in set C". So all that you do is count the number of values in the set {3,5} which happens to be two items.

Some books use absolute value notation to indicate the number of items. So some books may write |C| instead of n(C). This concept is known as set cardinality (or the cardinal value of a set).

n(C) = 2

Step-by-step explanation:

A set is given as C = {3, 5}. That means set C is having tow elements.

n(C) is referring the number of elements of the set C.

n(C) is also known as cardinality of the set.

In the given set number of elements are two so cardinality of the set n(C) is two.

Therefore, n(C) = 2 will be the answer.

x + 4/7

step-by-step explanation:

use cymath

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
