Answer 1

pi is irrational and is constantly used throughout the sciences and mathematics. So is the Golden ratio used by artists and numerous other applications. The square root of 2 is used in findig the diagonal of a square and the square root of 3 is used in finding the longer leg of a 30-60-90 degree triangle.

They are far from useless.

Answer 2

Any place where you use pi=3.14159... , or a square root, you will be using an irrational number. So anyplace where you'd be using a circle, or almost anywhere where you'd be using triangles where the sides don't come out to be integers, you'd be using irrational numbers. E.x. if you have a 31-inch TV, you're not going to find 2 integers for the sides, it's going to be an irrational number/square root. Just look around your house and find every example of a circle, and say that to find the area/circumference of the circle you'd be using pi.

Answer 3

In practical applications only rational approximations are
ever used since otherwise the decimals would be infinitely long. Thus, no irrational number is ever used in numerical calculations.

Answer 4

My answer does no longer substitute, because of the fact many females persons have felt this way contained in the area because of the fact the stay-at-residing house make sure. only on account which you do no longer earn an income does no longer mean you could no longer "placed on the pants". adult men in all possibility sense emasculated whilst they have not got a job, I think of, on account that in many circumstances lots of self-nicely worth is derived from employment. bear in mind, having a paying interest does no longer make you extra worth as a larger half. you're offering cost to the kin by using doing what you do. I as quickly as heard that a typical homemaker's "interest" would fee around $a hundred,000 to interchange if those issues have been employed out (nanny, prepare dinner, housekeeper, and so on.). Your spouse in all possibility feels down because of the fact she (like maximum persons) has been motivated by using her custom and buys into classic roles to a pair degree. She would desire to have secretly wanted she would desire to be the single at residing house and has a "romantic" view of it. perchance she thinks all you do is load the dishwasher, flow laundry, and play with the youngsters all day. If she thinks that, she believes you have a charmed existence. If she perspectives the area this way, perchance you will desire to get pals or kinfolk to computer screen the youngsters for some hours on the weekend. Spend it gradual alongside with your spouse out to dinner (regardless of if it extremely is quickly foodstuff and a walk contained in the park) and ask her if she wanted to be a stay-at-residing house mom. hear heavily, yet no remember what she says, persist with by using by using telling her how many belongings you do and how lots power it takes out of you to do those issues. i don't be attentive to how previous the youngsters are, yet even babies can study to make their beds, or help fold towels. If there's a church "mothers' holiday" software close to you, they're oftentimes loose or $5 in keeping with newborn, and furnish 2 mornings a week or so of alleviation newborn care. Many church homes see this as a ministry. Ask around and get that set up, in case you're able. that would desire to provide you a wreck. additionally, the spouse can do the grocery paying for, run a vacuum, or prepare dinner spaghetti. She's able-bodied, i anticipate. She would desire to be doing a splash chores. solid luck alongside with your learn! :)
