C/C' = .75
d = 3
C=pi x d = 3pi
C' = C/.75 = 4pi
Then since C' = 2r', r' =2

The equation of the newsletter function is C(x) = 75 + 0.25x and the function values are C(0) = 75, C(100) = 100, C(200) = 125 and  C(300) = 150

<h3 /><h3>How to determine the newsletter function?</h3>

From the question, the given parameters are

Initial charge = $75.00

Rate per copy = $0.25 per copy

The equation of the newsletter function is then calculated as

Total = Initial charge + Rate per copy x Number of copies

Let x represents the number of copies

So, we have

Total = Initial charge + Rate per copy x x

This gives

C(x) = 75 + 0.25x

<h3>The function values for x = 0, 100, 200 and 300</h3>

When x = 0, we have

C(0) = 75 + 0.25 x 0 = 75

When x = 100, we have

C(100) = 75 + 0.25 x 100 = 100

When x = 200, we have

C(200) = 75 + 0.25 x 200 = 125

When x = 300, we have

C(300) = 75 + 0.25 x 300 = 150

The length and width of a living room is 5.5 m and 4.8 m with an uncertainty of 0.1 m in each measurement. The perimeter of the
olga_2 [115]

Answer:

The perimeter of room is (20.6 \pm 0.4)~m

Step-by-step explanation:

We are given the following in the question:

The length and width of a room are measured with uncertainties.

There is  uncertainty of 0.1 m in each measurement.

Length = (5.5 \pm 0.1)~m

Width = (4.8 \pm 0.1)~m

Formula:

The perimeter of room is given by:

P = 2\times (\text{Length + Width})\\P = 2\times ((5.5\pm 0.1)+ (4.8\pm 0.1))\\= 2\times (10.3\pm 0.2)\\P = (20.6 \pm 0.4)~m

The uncertainties are also added and multiplied.

Thus,the perimeter of room is (20.6 \pm 0.4)~m
