The circumference of a circle is calculated by the formula here,

C is the circumference of the circle.

r is the radius of the circle.

π is 22/7 or 3.14.

In the given options π is not missing.

Therefore the formula that relates circumference and radius is C = 2πr.

Lines b and care parallel.
Vinil7 [7]

Answer:

<h3>Option 2 </h3>

angle 2 = 7x + 1 ( vertically opposite angles)

7x + 1 + 18x + 4 = 180° ( forming linear pair).

7x + 18x + 4 +1 = 180°

25x + 5 = 180°

25x = 180 - 5

25x = 175

x = 7°

angle 2 = 7(7)+ 1

= 50°

Given that weekly demand curve of a local wine producer is p = 50 − 0.1q, and that
rusak2 [61]

Answer:

Z(p) = -10p² + 600p - 6500

Step-by-step explanation:

Demand curve <em>p</em> = 50 - 0.1 <em>q</em>

Total cost function <em>C</em>(<em>q</em>) = 1500 + 10q

where q is the number of bottles produced each day and p is the selling prices per bottle.

Now, <em>p</em> = 50 - 0.1 <em>q</em>

o.1 <em>q = </em>50 <em>- p</em>

<em>q = </em>500 - 10<em>p</em>

Revenue = price × quantity =<em> p × q</em>

= <em>p</em> ( 500 - 10<em>p</em>)

= 500<em> p</em> - 10<em>p²</em>

Profit = total revenue - total cost

Let Profit be Z since profit is function of price, therefore

<em>Z(p) = pq - C(q)</em>

<em>Z</em> (p)=  500<em> p</em> - 10<em>p</em>² - (1500 + 10<em>q</em>)

Substituting the value of q in above expression,

<em>Z(p) </em>= 500 <em>p</em> - 10<em>p</em>² - ( 1500 + 10 (500 - 10<em>p</em>))

<em>Z(p)</em> = 500<em>p</em> -10<em>p</em>² - 1500 -5000 + 100<em>p</em>

<em>Z(p)</em> = -10<em>p</em>² + 600<em>p</em> - 6500

So, the weekly profit as a function of price p is Z(p) = -10p² + 600p - 6500.
