A jewelry store has 311.75 ounces of 14-carat gold in stock.

WARRIOR [948]

Answer:

$\boxed{\text{(a) 86 necklaces; (b) \$2220}}$

Step-by-step explanation:

(a) Number of necklaces

3⁵/₈ = 3.625

$\text{No. of necklaces} = 311.75\text{ oz} \times \dfrac{\text{1 necklace}}{3.625\text{ oz}} = \textbf{ 86 necklaces}\\\\\text{You can make } \boxed{\textbf{86 necklaces}} \text{ from 311.75 oz of 14K gold}$

(b) Value of gold in each necklace

There are 3.625 oz of 14K gold in each necklace. Pure gold is 24K.

$\text{Mass of pure gold} = \text{3.625 oz} \times \dfrac{\text{14K}}{\text{24K}} = \text{2.1146 oz}$

Pure 24K gold is worth $1050/oz.

$\text{Value of pure gold} = \text{2.1146 oz} \times \dfrac{\text{\$1050}}{\text{1 oz}} = \textbf{\$2220}\\\\\text{The value of the gold in each necklace is } \boxed{\textbf{\$2220}}$

Answer: 2

Step-by-step explanation:

Vertical asymptotes can be solved by setting the denominator equal to zero.

x(x+1) = 0

Solve for 0 now by setting both x and x+1 equal to zero

x = 0

x + 1 = 0

x = -1

Because there are two factors in the denominator, the answer would be two.

The graph of that function has 2 vertical asymptotes (one at x=0 and the other at x=-1)
