Natalka [10]

Answer: a) c(x) = 0.124x + 1.1, b) 13 units

Step-by-step explanation: Revenue function = R(x) = 0.21x

Profit function = p(x) = 0.086 - 1.1

Cost function = c(x) =?

Recall that profit = total revenue - total cost

Hence, total cost = total revenue - profit

c(x) = 0.21x - (0.086x - 1.1)

c(x) = 0.21x - 0.086x + 1.1

c(x) = 0.124x + 1.1

Break even point is the point where total revenue equals total cost

R(x) = c(x)

0.21x = 0.124x + 1.1

0.21x - 0.124x = 1.1

0.086x = 1.1

x = 1.1/0.086

x = 12.79 which is approximately 13 units

Q.1. Base and height if a parallelogram 12 cm and 8 cm respectively. Find its area.

irakobra [83]

Answer:

Area of the parallelogram is 96 $cm^{2}$ .

Step-by-step explanation:

A parallelogram is a quadrilateral with parallel and equal length of opposite sides. The diagonals are perpendicular to each other.

Area of a parallelogram is given as,

Area = base x height

Thus for the given parallelogram with base 12 cm and height 8 cm, the area would be;

Area = base x height

= 12 x 8

= 96

Area = 96 $cm^{2}$

The area of the parallelogram is 96 $cm^{2}$ .

Find the area of a trapezoid with bases that measure 9.2 CM and 7.7 cm and height 6.8 cm

maria [59]

$\bf \textit{area of a trapezoid}\\\\
A=\cfrac{h(a+b)}{2}~~
\begin{cases}
a,b=\stackrel{bases}{parallel~sides}\\
h=height\\
---------\\
a=9.2\\
b=7.7\\
h=6.8
\end{cases}\implies A=\cfrac{6.8(9.2+7.7)}{2}$
