For a recent year, the rate of first-class postage is as follows:
Law Incorporation [45]

Answer:

$0.95

Step-by-step explanation:

Given that weight of the function = x

Given that cost of the postage for mail having weight less than or equal to 1 oz = $0.44

then to find the equation can be written as

C(x)=0.44  where 0<x<=1

Similarly we can write equation for other parts

C(x)=0.61  where 1<x<=2

C(x)=0.78  where 2<x<=3

C(x)=0.95  where 3<x<=3.5

Now we can write them together as piecewise function as shown in below:

C(x)=\left\{\begin{matrix}0.44 & 0

to graph that we just draw horizontal lines for each as none equation contains x on the right side .

3.48 oz is less that 3.5 so we will use $0.95.

Which of the following shows the numbers in the box below listed in increasing order?
Anarel [89]

9514 1404 393

Answer:

  (A) -2, 3/7, 1/2, 1.2

Step-by-step explanation:

The numbers are in increasing order when they are listed left-to-right as they appear on the number line.

The only numbers that may give you trouble are 3/7 = 6/14 and 1/2 = 7/14.

The negative number is less than any positive number. 1.2 is greater than any fraction that is less than 1.

The correct ordering is found in choice A.

At noise pollution cellular,plan A is $30.00 per month and $5.00 for every gigabyte of data . Plan B is $50.00 per month and $2.
Romashka-Z-Leto [24]
Let x be the number of gigabyte of data used.

Plan A:
Total cost = 30 + 5x

Plan B:
Total cost = 50 + 2x

Irfan will use between 5 to 8 gb of data per month.

When x = 5
Plan A = 30 + 5(5) = $55
When x = 8,
Plan A = 30 + 5(8) = $70

When x =5,
Plan B = 50 + 2(5) = $60
When x = 8,
Plan B = 50 + 2(8) = $68

He is probably better off using Plan A. Plan A is a cheaper option up to 7gb of data. He should only swap to Plan B if he consistently use 8gb or more data per month.
