Age = no. of half lives x duration of each half life

ratio of Parent nuclei : Daughter Nuclei

1 : 15

total of 16 parts, and for every 16 parts one part is a parent nuclei

Mt = Mo x (0.5)^n

Mt = amount remaining

Mo = Initial amount

n = number of 1/2 lives

Mt = 1/16

(1/2)^n = 1/16

(1/2)^n = (1/2)^4

n=4

Age = 4 x duration of each half life

Age = 4 x 300

Age = 1200

Therefore, the age of the specimen is 1200 years.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

When a material goes through radioactive decay there is a new daughter product in the solid material so can this new daughter material react chemically with the rest of the solid matrix around it?

Yes, this new daughter is a different chemical element and will react differently chemically than the precursor element.


What is the daughter product of Xenon?

The main daughter product is Caesium.


Is Direct Material a product cost?

Yes direct material is a product cost as without material no product can be manufactured.


What is the use for neptunium?

It is the intermediate product between Uranium-238 and Plutonium-239. Uranium-239 decays to Neptunium-239 with a halflife of 23.5 minutes. Neptunium-239 decays to Plutonium-239 with a halflife of 2.33 days.


Is direct material used a product cost?

Yes direct material is part of product cost and included in calculating the product price.


Is Direct Material a product cost or period cost?

Direct material is a product cost because without material no product can be produce and it has direct relation with production of goods.
