Answer:

Explanation: As you make the segments smaller and smaller, the parallelogram becomes more of a rectangle with shorter side equal to the radius of the circle r and longer side πr - half of the circumference of the circle. Hence we get the formula πr2 for the area of a circle of radius r .

A company makes pens. They sell each pen for $9.
Allisa [31]

(a) The profit when the company sold 1000 pens is -1000.

(b) The number of pens that are required to sell in the break-even is 1167.

(a)

The profit when the company sold 1000 pens is

P = R - C

= 9x - (3x + 7000)

= (9 × 1000) - (3 × 1000 + 7000)

= 9000 - (3000 + 7000)

= 9000 - 10000

= -1000

(b)

The number of pens that are required to sell in the break-even is

R = C

9x = 3x + 7000

9x - 3x = 7000

6x = 7000

x = 1167

Therefore we can conclude that:

(a) The profit when the company sold 1000 pens is -1000.

(b) The number of pens that are required to sell in the break-even is 1167.
