Calculus

YOU CAN SOLVE FOR A VARIABLE IN AN EQUATION, BUT NOT AN EXPRESSION.. FOR EXAMPLE: RIGHT WAY: 4u+6=26

-6 -6

So you are left with 4u=20

now you divide the 4u by 4 because you want to do the

opposite of multiplying. also, you divide the 20 by 4.

So... u=5

x=20

Given these kind of questions, there are often several answers, if we are allowed to freely use the four normal ways of calulating. We will focus on one answer here, however.

We have four cars; two nines and two aces. Remember that the ace card is allowed two values: 1 and 14.

We don't need to complicate matters further, though. We can give one possible answer by simply adding the two aces with the highest value (14) and subtract the two 9's:

(14 + 14)-( 9 + 9) = 10

Written out: 28 - 18 = 10

I assume the question is about cos x = -1.

While it is true that cos x is negative in both the second and third quadrants, it reaches the value of -1 where the two quadrants meet, not inside the quadrants. The point where they meet is on the [negative] horizontal axis and x is -pi radians.

No. The vertical axis is the y-axis.

Well, y= mx + b, and y is y, m is slope (aka rise over run), x is x, and b is the y-intercept (aka where the line hits the vertical axis). So is y = 2x + 5, 2 means the same thing as b, and b is rise over run. So your answer is 2. Sorry if that's really confusing. I've made it as simple as I can, but at least to me math is confusing. Best of luck!

Yes.Here two variables X & Y are related in such a way that the ratio of their values always remains the same.

If for example: 4y = 16

Then: y = 4

x2 + 8x + 16 describes a parabola, and as such does not have an area as it does not enclose any space.

It does however have a range. If you factor it, you can reduce it to (x + 4)2, which tells us that it has a range of 0 → ∞, with it's focal point being at (-4, 0).

[ -x - 2 ] is not a question. It's an expression that stands for a number. In

order to figure out what number it stands for, we'd need to know what 'x' is.

if -x-2 had a result, then we can find what x equals. the only thing we can do with this information is simplify it to -(x+2)

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", "equals" etc.

The answer is that there is no such x - unless you define "plus" in some special way.

To calculate the first derivative of a function, you can follow these general steps:

Identify the function: Determine the function for which you want to find the first derivative. Let's assume your function is denoted as f(x).

Express the function: Write down the function in its general form, considering any constants or variables involved. For example, f(x) = 3x^2 + 2x - 1.

Differentiate the function: Use differentiation rules to find the derivative of the function. The derivative represents the rate of change of the function with respect to the variable. For example, to differentiate f(x) = 3x^2 + 2x - 1, apply the power rule and the sum rule as follows:

Power rule: For a term of the form ax^n, the derivative is d/dx(ax^n) = anx^(n-1).

Sum rule: The derivative of a sum of functions is the sum of their derivatives.

Applying these rules to the function f(x) = 3x^2 + 2x - 1:

The derivative of the term 3x^2 is 6x (using the power rule).

The derivative of the term 2x is 2 (using the power rule, where the exponent is 1).

The derivative of the constant term -1 is 0 (as the derivative of a constant is always 0).

So, the first derivative of f(x) = 3x^2 + 2x - 1 is f'(x) = 6x + 2.

Simplify if necessary: If there are any further simplifications or rearrangements possible, apply them to obtain the final form of the first derivative.

In summary, the process involves differentiating each term of the function with respect to the variable and then simplifying the resulting expression. Differentiation rules such as the power rule, sum rule, product rule, and chain rule can be used depending on the complexity of the function.
