If M is the set of all square numbers less than 80 and N is the set of all non-negative even numbers that are under 30, a Write the lists of all elements of M and N,

1. M = {(–8)^2, (–7)^2, (–6)^2, (–5)^2,

(–4)^2, (–3)^2, (–2)^2, (–1)^2, 0^2, 1^2, 2^2, 3^2, 4^2, 5^2, 6^2, 7^2, 8^2}

2. N = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28}

Step-by-step explanation:

Data obtained from the question.

M = {set of all square of numbers less than 80}

N = {set of all non-negative even numbers that are under 30}

The elements of set M and N can be obtained as follow:

1. Square of all numbers less than 80 = (–8)^2, (–7)^2, (–6)^2, (–5)^2,

(–4)^2, (–3)^2, (–2)^2, (–1)^2, 0^2, 1^2, 2^2, 3^2, 4^2, 5^2, 6^2, 7^2, 8^2

Thus, we can write set M as:

M = {(–8)^2, (–7)^2, (–6)^2, (–5)^2,

(–4)^2, (–3)^2, (–2) ^2, (–1)^2, 0^2, 1^2, 2^2, 3^2, 4^2, 5^2, 6^2, 7^2, 8^2}

2. All non-negative even numbers that are under 30 = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28

Thus, we can write set N as

N = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28}

your answer is a

step-by-step explanation:

4*4*4*4=256

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
