AD=DC, because BD is a bisector of AC.

BD is in common.

AD and BD are perpendicular, and so are DC and BD, because BD is perpendicular to AC.

AB^2 = AD^2+BD^2 because ABD is right

BC^2 = DC^2+BD^2 because BDC is right

AB=BC because AD=DC

So, AD=DC, AB=BC and BD is common, and the triangles are congruent.

Josh has 8 days to make pots and plates to sell at a local fair. Each pot weighs 2 pounds and each plate weighs 1 pound. Josh ca
sweet-ann [11.9K]

The optimal number of pots and plates Josh should make is given from

the graph of the inequalities.

Response:

a. 2·p + a ≤ 50

p ≤ 24

a ≤ 40

b. The coordinates of the vertices of the feasible region are; (24, 2), (40, 5), (0, 40), (24, 0), (0, 0)

c. 40 pots and 5 plates

<h3>How can the optimal number of plates and pots Josh should make be found?</h3>

Given:

Number of days Josh has to make pots and plates to sell = 8 days

Weight of each pot = 2 pounds

Weight of each plate = 1 pound

Weight Josh cannot carry = More than 50 pounds

Number plates he can make each da = At most 5 plates

Number of pots he can make each day = At most 5 pots

The profit Josh makes for each plate sold = $12

Profit from each pot sold = $25

a. Let <em>p</em> represent the number of pots Josh makes and let <em>a</em> represent the

number plates. The linear inequalities are;

2·p + a ≤ 50

p ≤ 8 × 3 = 24

p ≤ 24

a ≤ 5 × 8 = 40

a ≤ 40

b. When p = 24, we have;

2 × 24 + a = 50

a = 2

When <em>a</em> = 40, 2·p + 40 = 50, gives;

p = 5

The vertex points are;

The coordinates of the vertices of the feasible region are;

(24, 2), (40, 5), (0, 40), (24, 0), (0, 0)

c. The profit function is; P = 25·p + 12·a

The profit at the vertices are;

\begin{tabular}{|c|c|c|}p&a&Profit\\0&0&0\\0&40&12 \times 40 = 480\\24&0&25 \times 24 = 600\\24&2&12 \times 2 + 25 \times 40 = 624\\40&5&12 \times 5 + 25 \times 40 = 660\end{array}\right]

To maximize his potential profit, therefore;

  • <u>Josh should make 40 pots and 5 plates</u>.
