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.

The cost to mail a letter that is 3.48 ounces is \boxed{\$ 0.95}.

Further explanation:

The piecewise defined function is defined as a function that takes different values in different interval. It is defined on the sequence of intervals.

Given:

The price to mail a weight not over 1 ounce is \$0.44.

The price to mail a weight not over 2 ounce is \$0.61.

The price to mail a weight not over 3 ounce is \$0.78.

The price to mail a weight not over 3.5 oounce is \$0.95.

Explanation:

If the weight of the letter is less than or equal to one ounce then the cost is \$0.44.

Then function can be expressed as follows,

P\left( x \right) = \$ 0.44\,\,\,\,\,\,\,0 < x \leqslant 1

If the weight of the letter is greater than 1 ounce and less than or equal to 2 ounce then the cost is \$0.61.

Then function can be expressed as follows,

P\left( x \right) = \$ 0.61{\kern 1pt} {\kern 1pt} {\kern 1pt} {\kern 1pt} {\kern 1pt} {\kern 1pt} {\kern 1pt} 0 < x \leqslant 1

If the weight of the letter is greater than 2 ounce and less than or equal to 3 ounce then the cost is \$0.78.

Then function can be expressed as follows,

P\left( x \right) = \$ 0.78\,{\kern 1pt} {\kern 1pt} {\kern 1pt} {\kern 1pt} {\kern 1pt} {\kern 1pt} 0 < x \leqslant 1

If the weight of the letter is greater than 3 ounce and less than or equal to 3.5 ounce then the cost is \$0.95.

Then function can be expressed as follows,

P\left( x \right) = \$ 0.95\,\,\,\,\,\,3 < x \leqslant 3.5

The piecewise defined function can be expressed as follows,

P\left( x \right) = \left\{ \begin{aligned}0.44\,\,\,\,\,\,\,\,0 &< x \leqslant 1 \hfill\\0.61\,\,\,\,\,\,\,\,\,1 &< x \leqslant 2 \hfill\\0.78\,\,\,\,\,\,\,\,2 &< x \leqslant 3 \hfill\\0.95\,\,\,\,\,\,\,\,3 &< x \leqslant 3.5 \hfill\\\end{aligned}\right.

The cost to mail a letter that is 3.48 ounces is \boxed{\$ 0.95}.

Factor completely 2x3 + x2 - 18x - 9
melisa1 [442]
Factor the following:
2 x^3 + x^2 - 18 x - 9

Factor terms by grouping. 2 x^3 + x^2 - 18 x - 9 = (2 x^3 + x^2) + (-18 x - 9) = x^2 (2 x + 1) - 9 (2 x + 1):
x^2 (2 x + 1) - 9 (2 x + 1)

Factor 2 x + 1 from x^2 (2 x + 1) - 9 (2 x + 1):
(2 x + 1) (x^2 - 9)

x^2 - 9 = x^2 - 3^2:
(2 x + 1) (x^2 - 3^2)

Factor the difference of two squares. x^2 - 3^2 = (x - 3) (x + 3):

Answer:  (x - 3) (x + 3) (2 x + 1) thus the Answer is C.

8(7 + 23) = 8(7) + 8(?)
34kurt
Answer: 23

When using multiplication with brackets, you multiply the number by all the numbers within the bracket before adding them together.

Therefore when it is 8(7 + 23) it basically means: 8(7) + 8(23)
