A company sells a batch of 419 items for $57 each. The

zubka84 [21]

Answer:

Profit = $ 8,262

Explanation:

<u>1. Model:</u>

i) Profit = Revenue - Cost

ii) Revenue = price × number of items

iv) Cost = variable cost + fixed expense

<u>2. Solution</u>

i) Revenue = $ 57 / item × 419 items

ii) Cost = $ 23 / item × 419 items + $5,984

iii) Profit = $ 57×419 - ($23×419 + $5,985)

Profit = $ 23,883 - ($ 9637 + $ 5,984) = $ 23,883 - $ 15,621

Profit = $ 8,262 ← answer

Andrea has just created a scale drawing of her bedroom room which is 18 feet long by 12 feet wide. The scale drawing shows the l

vivado [14]

Width of the scale drawing is 4 inches

Step-by-step explanation:

We can solve this problem by using the rule of three.

In fact, the actual size of the bedroom are:

$L=18 ft$ (length)

$W=12 ft$ (width)

In the drawing instead, the actual sizes on scale are

$L' = 6 in$ (length in the scale drawing)

$W'$ (width in the scale drawing)

Therefore, applying the rule of three,

$\frac{L'}{L}=\frac{W'}{W}$

And solving for W', we find the width on the scale drawing:

$W'=\frac{L'W}{L}=\frac{(6 in)(12 ft)}{18 ft}=4 in$

So, the width on the scale drawing is 4 inches.

The model below represents 4 x + (negative 4) = negative 2 x + 8.

ikadub [295]

Answer:

x = 2

Step-by-step explanation:

4 x + (negative 4) = negative 2 x + 8

4x + (-4) = - 2x + 8

4x - 4 = - 2x + 8

4x + 2x = 8 + 4

6x = 12

$x = \frac{12}{6} \\ \\ x = 2$

How does the graph of f(x)=5 cos(1/2x)-2 differ from the graph of g(x)=5 cos(x)-2

crimeas [40]

F(x) = 5cos(1/2x) - 2
g(x) = 5cos(x) - 2

The period for a cosine function is 2pi/k
In the equation the k is located before the variable.
In g(x) we have 5cos (1x) -2
so the period is 2pi/1 or 2pi. This means the length of one full period of cosine will go from 0 to 2pi.

In f(x) we have 5 cos (1/2 x) - 2
so the period is 2pi/ (1/2) which is the same as 2pi * 2 or 4pi.
This means the period for the function is 4pi and the length of one full period of the cosine graph will go from 0 to 4pi.
The length of f(x) will be longer than that of g(x) .
