Write the coordinates of the vertices after a reflection over the y-axis.​
andre [41]

The vertices coordinates following a reflection along the y-axis are S(-6,6), T(2,6), U(2,0), V(-6,0).

<h3>What is reflection?</h3>

A reflection point is created when a figure is constructed around a single point known as the point of reflection or the figure's centre. There is an exact opposite point on the other side of each point in the figure. Under the point of reflection, the figure's size and shape are unaltered.

Given points are p ( 8,-2 ) Q(8,5) R( 4,-2 )

The reflection of the points

P (8,-2) = P (-8, 2)

Q (8,5) = Q (-8, -5)

R (4,-2) = R (-4, 2)

Therefore, the coordinates of the vertices after a reflection across the Y-axis are P (-8, 2)  Q (-2, 6)  R (-2, 0)

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}}
