Calculus

Assuming the equation described is: w = (Cr)-2...

Remember that any value to a negative power can also be represented like this:

(Cr)-2 = 1/(Cr)2

Also note that we can distribute the power over multiplication. (This doesn't apply to addition!)

(Cr)2 = C2r2

So if we rewrite the equation with this, we get

w = 1/(C2r2)

If we invert both sides and then divide by C2 on both sides, we get

1/w = C2r2 → 1/(wC2) = r2

Take the square root of both sides, and you'll have the equation in terms of r:

r = sqrt[1/(wC2)]

The biggest step was realizing that anything to a negative power can be inverted to find the same with a positive power. For example, 2-2, if you type it in your calculator, gives you 0.25, or 1/4. If we do what we did above, we can take 2-2 and make it 1/(22), which also equals 1/4. This applies to any negative power, and is a powerful technique for solving equations with negative exponents.

Twice. Between negative two and negative one.

.3x=72.3

which implies, x=72.3/.3=241

If x=-17/73 then -x=17/73

Yes and no, it depends on whether you are willing to accept non-integers:

Square root of 90 is 9.486832981... so A^2 - 90 = (A - 9.486832981...)(A + 9.486832981...)

It is x + 7. It is not an equation and so cannot be solved, and it cannot be evaluated without information about x.

yep

' 18 ' is not in fraction form. It looks like the job is done.

X= 6

10x + 9 = 8x + 21. subtract 8x and 9 to both sides

2x = 12. divide by 2 to both sides

x = 6

x^2-x-56=(x-8)(x+7)

6t2-13t-63 = (3t+7)(2t-9) when factored.

This is stupid! Why do you even need m help?!

Yes.

A meter has 100. Centimters and cube means three times. Means divide it by 100 x100 x 100

5 + 3 * 32 = 5 + 96 = 101

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals", "squared".

The question does not contain an equation nor an inequality so there is not much that can be done with it.

Three, each time that x changes 1 y changes 3. C is where the start is.

Using the quadratic formula, x = 0.5*[2 ± sqrt(4 + 4*1*9)]

= 0.5*[2 ± sqrt(40)]

= [1 ± sqrt(10)]

= -2.162278 and 4.162278 (to 6 dp)

line up the decimal points,

and add them

1/2*(-3x) = 5

Multiply both sides by 2: -3x = 10

Divide both sides by -3: x = 10/(-3) = -31/3

Indirect. When x increases, y decreases. ( and conversely).
