On the futures market, the price of gold is quoted in dollars per troy ounce, and each gold contract guarantees the delivery of 100 troy ounces of gold. If Brent bought 2 gold ounces at $1,400 per troy ounce, and some of the gold was delivered to him in 1-kilogram bricks, what was the purchase price of each 1-kilogram brick, to the nearest dollar? (Note: 1 troy ounce=31.103 grams) A) $9,002 B) $22, 506 C) $45,012 D) $560,000

dunno

step-by-step explanation:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
