Calculus

A wrong answer because the right answer is 8

I assume the apostrophes represent feet; it really doesn't make sense to multiply four numbers together. Or at least, in most situations it wouldn't make sense. You would have feet to the fourth power; but we only live in a three-dimensional world. Anyway, if you want to know how much it is, just multiply the four numbers together. The answer will be in feet to the fourth power ... whatever that means.

One place where such measurements can be used is to specify the work done by a pump - if you multiply the volume of water pumped (say, in cubic feet) by the height (say, in feet), you get feet to the fourth power - which is actually (once you consider some implicit factors) a measurement of the work done by the pump.

f(x)=2x+2. Put in 0, 1/2, 1, 3/2, 2... and you will get integer values. That is for the domain. The numbers you get when you put that in are the range integral values.

The ordered pair is (1, 1).

The answer is - not are : (5, 1).

x2-2x-3 = 0

(x+1)(x-3) = 0

x = -1 or x = 3

This is not calculus. Please post this in the correct forum.

However, 2x2 - 3x2 +5x - 4 = -1

therefore -x2+4x-3 = 0

therefore x2-4x+3 = 0

therefore (x-3)(x-1)=0

therefore x = 3 or x = 1.

Put your questions in the correct category. Makes then more likely to be answered correctly.

Consult your doctor if you don't know.

its easy just maximize the four into the irregular eight that in thus giving it nine that is only in mathematical terms people

Use the discriminant to find out.

b^2 - 4ac

a = 2

b = 1

c = - 1

1^2 - 4(2)(- 1)

1 + 8 = 9 > 1

so, there are two real roots to this equation. ( two real solutions )

Because median is the mid of the class intervals. Therefore, it is a positional measurement. Hence, if the size of class interval increases or decreases then the middle position will also increase or decrease and thus median.

Yes.

If: -2x+5 = -17

Then: x = 11

If: 4/3y = 1

Then: y = 4/3

6y = 12x+32

Divide all terms by 6:

y = 2x+5 and 1/3 which is now in slope intercept form

Go under "Settings", then my "account", you will need to be referred so put the bonus code of "rod12" and put your info. You should be all set. regards, Rod

It is a little unclear what you mean by 2 x 4. 2 x 4 is normally a measurement for the width and depth of wood in inches but I doubt you are interested in calculating an area based on depth and width. It is more likely you are interested in calculating an area based on length and width. So it becomes important to know what these measurements are. Either you have not supplied the length here or you have but failed to tell us what the unit is. 4 by 2 what? Inches?

12x4 - 3x2 cannot be simplified because the different exponents says that they are not like terms

yes, go to view and then hide bookmarks

78 - (-49) is the same as 78 + 49 which equals 127
