4. Represent the following sets in Roster form.
Phoenix [80]

The roster form of the given sets are:

(i) A = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19}.

(ii) B = {1, 2, 3, 4, 5, 6, 7}.

(iii) C = {27, 64}.

(iv) D = {-1, 0, 1}.

The roster form of any set is the set with all elements of the set written in the set.

In the question, we are asked to represent the known sets in the roster form.

(i) A=The set of all odd natural numbers less than 20.

The set of all natural numbers, that is numbers after 1.

Odd numbers are numbers of the form 2n - 1.

Thus, the roster form is: A = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19}.

Going similarly to the others, we will get:

(ii) B={y: y = n, n ∈ N, n ≤7}

Roster form is, B = {1, 2, 3, 4, 5, 6, 7}.

(iii) C = {x: x is a perfect cube, 8 < x < 125}

Roster form is, C = {27, 64}.

(iv) D= {x: x ∈ Z, -2 < x < 2}​.

The roster form is, D = {-1, 0, 1}.

PLEASE HELP!!
ElenaW [278]

Answer:

-1 and -3

(n+7)(n-8)

Step-by-step explanation:

1. Find the Zeros

f(x)=x^{2} +4x+3

f(x)=\left(x+1\right)\left(x+3\right)

x+1=0\\x=-1\\x+3=0\\x=-3

2. Factoring Trinomials

f(x)=n^{2} -n-56

f(x)=\left(n+7\right)\left(n-8\right)

n+7=0\\n=-7\\n-8=0\\n=8

What is the least prime number greater than 50?
uysha [10]
A prime number is a number that has only two factors: 1 and itself
For example, the number 7 has two factors: 1,7 This makes 7 a prime number
Since the number has to be greater than 50, we can go to the next whole number; 51
51 has four factors, 1,3,17,51 This is not our prime number
52 is even so obviously it's not prime because you can divide by two
53 has only two factors; 1,53 This means that its prime and the answer is 53 :)
