What is the area of a rectangle of 5/9 m in length and 7/8 m in width

Andru [333]

Answer:

35/72 $m^2$

Step-by-step explanation:

Rectangle Formula: $l*w=Area$

Switch the variables with the numbers given:

$\frac{5}{9} *\frac{7}{8} =Area$

Multiply the top and bottom:

5*7 = 35

9*8 = 72

35/72 = Area

Suppose that the dollar cost of producing x appliances is c(x)=1000+ 90x- 0.2x 2

Aleksandr [31]

Answer:

Step-by-step explanation:

Given that the dollar cost of producing x appliances is

$c(x)=1000+ 90x- 0.2x^2$

A) Average cost can be obtained by dividing c(x) by units = x

i.e. average cost = $\frac{1000}{x} +90-0.2x$

B) Marginal cost = dC/dx = $90-0.4x$

When x=140 marginal cost $= 90-0.4(140)\\=34$

C) We calculate

c(140) = $=1000+90(140)-0.2(140^2)\\\\=9680$

c(141) = $=1000+90(141)-0.2(141^2)\\\\\\=9713.80$

Marginal cost = difference = 33.80

Same as 34 shown in marginal cost.
