Consider U = {x|x is a negative real number}. Which is an empty set? {x|x ∈ U and x has a negative cube root} {x|x ∈ U and x has a negative square root} {x|x ∈ U and x is equal to the product of a positive number and –1} {x|x ∈ U and x is equal to the sum of one negative and one positive number}

Answers

Answer 1

Answer:

{x\ x e U and x has a negative square root} is an empty set.

Step-by-step explanation:

If x e U, x is a negative real number, and they don't have a square root (they don't have even roots). Their square roots are complex numbers, not real ones.

Answer 2

The set that will give an empty set will be {x|x ∈ U and x has a negative square root}

What is a set?

A set is a collection of numbers or objects. They are not necessarily arranged in pattern.

Given the following sets

r U = {x|x is a negative real number}

We are to determine the set that is empty. This means we need the set of numbers that are not real numbers.

The square root of a negative number will give a complex number. Hence the set that will give an empty set will be {x|x ∈ U and x has a negative square root}

A: x= -9
B: x= -9/11
C: x= 9
D: x= 9/11

Answers

Answer:

x = 9/11

Step-by-step explanation:

5x = -6x + 9

Add 6x to both sides

11x = 9

Divide both sides by 11

x = 9/11

Answer:
X Equals 9/11

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable. So X will equal 9/11, which in decimal form is 0.81.

A tree measured 12 1/2
feet tall. Over the next 5 1/2
years it grew to be 51 feet tall.

During the 5 1/2
years, what was the average yearly growth rate of the tree?

Answers

Answer:4.08 ft a year or 1 and 5/8 feet a year (approx)

Step-by-step explanation:

It's  12.5 feet the first year

51 feet 5 years later

If you do the math and divide 51 by 12.5, you get 4.08 which is around 1 and 5/8 ft

12.5x4.08 is  51 feet.

So the tree grows approximately 1 and 5/8 feet a year

Radian is a more advanced degrees measurement that is easier to use in trigonometry physics etc.

=126/180*2pi(rad)

=63/90*2pi(rad)

2x + 3 + 4x + 6 + 12x + 18 = 477

Please answer with solving steps. Thanks guys :)

Answers

Answer:

x= 25

Step-by-step explanation:

2x + 3 + 4x + 6 + 12x + 18 = 477

FIRST combine like terms

take all "x"

2+4+12= 18x

take all whole numbers

3+6+18= 27

18x+27= 477

now solve for x

-27 on both sides

18x= 450

÷18 on both sides

x= 25

yoi have to add the variables so 2x +4x+12x=18x and concombine like terms so 3 +6+18=27 so you have to put tbat together 18x+27=477 then you have to get x alone so you have to subtract 27 in both sides 27-27=0 then 477-27=450 then you have to do the oppsite of multiply so you have to divide 18x/18x and 450/18x 18÷18 is 1 so you just have to put x and then divide 450÷18=25 so x=25.

There are GCF of two numbers is three and the LCM is 180. If one of the numbers is 45,what is the other number ?

Answers

Answer:

The other number is 12

Step-by-step explanation:

There are GCF of two numbers is three and the LCM is 180. If one of the numbers is 45,what is the other number ?

Let us represent the other number as x

There are GCF of two numbers is three and the LCM is 180.

Therefore:

45 × x = 3 × 180

45x = 3 × 180

x = 3 × 180/45

x = 12

Therefore, the other number is 12

6x + 10 = 52

Answers

x = 7
(6)(7) + 10 = 52
42 + 10 = 52

Answer:

7

Step-by-step explanation:

well let’s just think that there’s already 10. let’s ignore the 10 for later.

now let’s think about 6x. of course the x is unknown (variable) which we have to find, so what you want to do, (easy way) think of every multiple of the number 6. so that of course includes 6, 12, 18... etc. now if you continue, you will get to the number 42. now it might not click right there but 42... is what we need since we already have the 10. since 42 + 10 = 52, now we just need to find out what 42 divided by 6 is... 7! 7x6 or 7(6) is 42, plus the starting 10 is 52!

therefore, x = 7.

A truck weighs 3.5 tons. How many pounds does the truck weigh? I'm confused on this.. here, there is this also,Egyptian ReligionThe Egyptian GodsThe first written records of religious practice in Egypt come from around 3400 BCE in the Predynastic Period of Egypt (6000-3150 BCE). Deities such as Isis, Osiris, Ptah, Hathor, Atum, Set, Nephthys, and Horus were already established as potent forces to be recognized fairly early on. The Egyptian Creation Myth is similar to the beginning of the Mesopotamian story in that, originally, there was only chaotic, slow-swirling waters. This ocean was without bounds, depthless, and silent until, upon its surface, there rose a hill of earth (known as the ben-ben, the primordial mound, which, it is thought, the pyramids symbolize) and the great god Atum (the sun) stood upon the ben-ben and spoke, giving birth to the god Shu (of the air) the goddess Tefnut (of moisture) the god Geb (of earth) and the goddess Nut (of sky). Atum had intended Nut as his bride but she fell in love with Geb. Angry with the lovers, Atum separated them by stretching Nut across the sky high away from Geb on the earth.Although the lovers were separated during the day, they came together at night and Nut bore three sons, Osiris, Set and Horus, and two daughters, Isis and Nephthys. Osiris, as eldest, was announced as Lord of all the Earth when he was born and was given his sister Isis as a wife. Set, consumed by jealousy, hated his brother and killed him to assume the throne. Isis then embalmed her husbands body and, with powerful charms, resurrected Osiris who returned from the dead to bring life to the people of Egypt. Osiris later served as the Supreme Judge of the souls of the dead in the Hall of Truth and, by weighing the heart of the soul in the balances, decided who was granted eternal life. The Egyptian AfterlifeThe Egyptian afterlife was known as the Field of Reeds and was a mirror-image of life on earth down to ones favorite tree and stream and dog. Those one loved in life would either be waiting when one arrived or would follow after. The Egyptians viewed earthly existence as simply one part of an eternal journey and were so concerned about passing easily to the next phase that they created their elaborate tombs (the pyramids), temples, and funerary inscriptions (the Pyramid Texts, the Book of the Dead) to help the souls passage from this world to the next.The gods cared for one after death just as they had in life from the beginning of time. The goddess Qebhet brought water to the thirsty souls in the land of the dead and other goddesses such as Selket and Nephthys cared for and protected the souls as they journeyed to the Field of Reeds. An ancient Egyptian understood that, from birth to death and even after death, the universe had been ordered by the gods and everyone had a place in that order.
