need the answer asap the cost to produce a product is modeled by the function f(x) = 5x2 − 70x + 258 where x is the number of products produced. complete the square to determine the minimum cost of producing this product. a: 5(x − 7)2 + 13; the minimum cost to produce the product is $13. b: 5(x − 7)2 + 13; the minimum cost to produce the product is $7. c: 5(x − 7)2 + 258; the minimum cost to produce the product is $7. d: 5(x − 7)2 + 258; the minimum cost to produce the product is $258.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
