Which of the following sets represents M∪N?{2, 5, 8}
{4, 7}
{3, 4, 6, 7, 9}
{3, 6, 9}
Which of the following sets represents M∪N? {2, 5, 8} - 1

Answers

Answer 1
Answer:

Answer : {3, 4, 6, 7, 9}

To find the set that represents M∪N, we take union of M  and N

For union of M and N, we consider all the numbers inside the circles M and N.

WE have 9 and 3 inside M. Also we have 6 inside N. 4 and 7 are in the intersection of M and N. So we consider 4 and 7 as well

M∪N = 9,3,6,4 and 7

{3, 4, 6, 7, 9} is the answer.

In this problem it just goes left to right, 1-18+25 = -17+25 = 8
(1-18)+25-17+25=8

The Mitchells are renting a boat for the day. It costs $100, plus $20 for each hour. They have to pay for a whole hour even if they are not out there for a whole hour. For example if they boat for 3 and a half hours, they have to pay for 4 hours. They don't want to spend more than $250 for the day. How many hours can they boat? Write an inequality and solve.A)100 + 20x ≤ 250. They can boat for 7 hours.

B)100 + 20x ≥ 250. They can boat for 8 hours.

C)100 + 20x ≤ 250. They can boat for 8 hours.

D)100 + 20x ≥ 250. They can boat for 7 hours.

Answers

A)100 + 20x ≤ 250. They can boat for 7 hours.

Think of this logically. They want to spend less than $250 on the boat, so it can't be more than.

100+20*(7)=240
It would have to be A because B means they can spend over 250 dollars. C would be 260, which is over 250 and D means they could use the boat for more time, costing more money.

Which is a zero of the function f(x) = 2x - 10?

Answers

f(x)=2x-10\n\na\ zero\ if\ 2x-10=0\n\n2x=10\ \ \ /:2\n\nx=5\n\nAnswer:The\ zero\ is\ x=5.
Watch carefully:

A 'zero' of the function is a value of 'x' that makes the function zero.

2x - 10 = 0

Add 10 to each side:

2x = 10

Divide each side by 2 :

x = 5

f(5) = 0

Triangle ABC has side lengths 18,24, and 30. Do the side lengths form a Pythagorean triple? Yes or No?

Answers

Answer:  Yes, the side lengths form a pythagorean triple.

Step-by-step explanation:  Given that the side lengths of triangle ABC are as follows :

AB=18,~~BC=24,~~CA=30.

We are to check whether the side lengths form a pythagorean triple or not.

For making a pythagorean triple, the side lengths must satisfy the following :

AB^2+BC^2=CA^2.

We have

AB^2=18^2=324,\n\nBC^2=24^2=576,\n\nCA^2=30^2=900.

So,

AB^2+BC^2=324+576=900=CA^2.

Thus, the side lengths will form a pythagorean triple.
yes, the equation is a^2+b^2=c^2 so if u take 18^2+24^ it equals 900 so to test that you take 30^2 which is = to 900 also so yes
