k = - 2 is excluded from the domain

the denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that k cannot be

solve k + 2 = 0 ⇒ k = - 2 ← excluded value

The open tray shown in the illustration is to be manufactured from a 18-by-19-inch rectangular sheet of metal by cutting squares
defon
Answer: You should cut out squares that are 4 inches by 4 inches.

One of the ways to do this problem is write and graph an equation. We can write an equation for the volume of this shape and then use a graphing calculator to graph it. If we look where the graph crosses 440, we will have our solution.

The volume needs to be 440. If we let x equal the side of the square that is cut out, we have the following dimensions.

Length = 19 - 2x
Width = 18 - 2x
Height = x

Volume = LWH

So our equation could be: y = (19 - 2x)(18 - 2x)x

If you graph that equation, it will intersect at the point (4, 440). Therefore, our square could be 4 by 4 inches.

What is the area of a triangle with a base of 2.4 cm and a height of 0.8 cm?
Andrej [43]
The easiest way to find the area of a triangle is by doing 1/2 base x height. So halve the base, 2.4 / 2 = 1.2. Now do 1.2 x 0.8. Which equals 0.96.

10 free points if you know answer to the question. always loooking to make peoples days better!
ira [324]

What you need to know in order to answer this:

       In math, the symbol " ! " is used to indicate "factorial".
       "Factorial" means the product of the integers from 1
       up to the number.

Examples:

       
2 !  =  "two factorial"  =  1 * 2  =  2

        4 !  =  "four factorial"  =  1 * 2 * 3 * 4  =  24

For this question:

  10 !  =  "ten factorial"  =  1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 * 10

                                       =  3,628,800 .

If you look at your calculator very closely, I'll bet you
there's a key on it marked " x ! " .
Enter a whole number into the calculator, and that key
gives you the factorial of the number.

And by the way, the points aren't 'free'.  I had to
give you some information in order to earn them.

Which is true regarding the function ?
USPshnik [31]
The answer is D. 

F(x) = y is basically what you are looking for. You substitute x for x and find if it matches with Y. D is the only answer where the ordered pair (-6, 10) ,matches up with F(x) = y.

19 tens + 11 tens what's the answer
Strike441 [17]
First we can either add 19 and 11, or we can do this another way.

19 + 11 = 30     To find how much thirty tens are, just add a 0 on the end of 30: 300

The other longer way to do it is: add a 0 to 19: 190, then add a 0 to 11: 110

110 + 190 = 300

There is your answer!
