A jeweler wants to minimize business costs and has found that the average cost in dollars per necklace is given by C(x)=0.5x^2-7
Vika [28.1K]

Answer:

The maximum cost is 41 dollars per necklace.

Step-by-step explanation:

The average cost in dollars/necklace is given by :

C(x)=0.5x^2-7x+65.5  .....(1)

Where

x is the number of necklaces that are created

To maximize the cost, find the value of x by putting dC/dx = 0

\dfrac{d}{dx}(0.5x^2-7x+65.5)=0\\\\x-7=0\\\\x=7

Now put the value of x = 7 in equation (1).

C(x)=0.5(7)^2-7(7)+65.5\\\\=41\ \text{dollars per necklace}

Hence, the maximum cost is 41 dollars per necklace.

​ Quadrilateral ABCD ​ is inscribed in this circle.
Sunny_sXe [5.5K]

Answer: m\angle A=116\°

Step-by-step explanation:

The missing figure is attached.

For this exercise it is important to remember that, by definition, the opposite interior angles of an inscribed quadrilateral are supplementary, which means that their sum is 180 degrees.

Based on this, you can identify that the angle D and the angle B are opposite and, therefore, supplementary.

Knowing that, you can write the following equation:

x+28\°=180\°

Now you must solve for "x" in order to find its value. This is:

x=180\°-28\°\\\\x=152\°

Then:

m\angle D=152\°

You know that:

m\angle A=(x-36)\°

Therefore, since you know the value of "x", you can substitute it into   m\angle A=(x-36)\° and then you must evaluate, in order to find the measure of the angle A. This is:

 m\angle A=152\°-36\°\\\\m\angle A=116\°
