Calculus

The answer will depend on x, and whether x is measured in degrees or radians.

viscosity is inversily change with the conductivity

Are you stupid, or just acting like you are???? Carefull, you might get stuck in the stupid mode...

the answer to that question would be 2 because -3 + 9 would be 5 - 3 and would be 2.

If

2x - 13 = 5

then

2x = 5 + 13 (we have in effect added 13 to both sides of the equation in this step)

2x = 18

x = 9.

The locus of points between 2 lines will always be another line that is halfway between the original 2 lines. In this case, that will be a line halfway between y=-2 and y=8, and since 3 is halfway between -2 and 8, the locus will be the line y=3.

First, solve for y.
y=-8x
if x=2, then y=-16.

Yes. You can make sense of this by referring to the definition of a derivative:

f'(x) = lim h goes to 0 of (f(x+h)-(fx))/h

As long as f(x+h) (as h goes to 0), and f(x) are defined so is f'(x). In fact, the only way f' is defined is if f(x) is defined.

No. A simple example of this is y = x2; the inverse is x = y2, which is not a function.

its a straightline. All points y where x is equal to 100. So its a vertical line covering the whole real line in the Y plane through x = 100

What do you mean?

As this is a calculus question, I presume that you are asking for a derivative or integral

The derivative of any function of the form

ƒ(x) = a * x ^ n

is

ƒ'(x) = a * n * x ^ (n-1)

The integral of any function of the form

∫ a*x ^ n

is

a / (n+1) * x ^ (n+1) + C

Your function that you gave is 1 / x^(2)

which is equal to:

x^(-2)

Thus the derivative is:

-2 * x^(-3)

And the integral is:

-x^(-1) + C

(1, 0.2), (2, 0.1)

You don't, unless you know either the value of x or what the expression equals.

Negative 1 times 8 is negative 8.

-1 x 8 = -8

The integral of 2 is "who gives a $%&#." You need to know what 2 is relating to and what the 2 means. If the question is "What is the integral of 2 dx" the answer would be "2x + c," with c being a constant.

If you instead wish to know what the integral of 2 dy, the answer is very different. (2y +c)

Yes, the concavity of a curve can be determined by differentiation. To find out the concavity of a graph at various points, you want to analyze the second derivative (f''(x)). Take the derivative of your original equation, then, take the derivative of this equation. By setting this second derivative to zero, you can solve for the critical points (x-intercepts/asymptotes) of the second derivative graph. Once these critical points are found, make a number line with these points marked. By doing a sign test on either sides of the critical points (plug in numbers below and above the critical points into the second derivative equation), you can find the concavities of your original graph. Wherever the sign tests results in a positive number, that is where a upward facing curve is (concave up); where it is negative, that is where a concave down portion is.

It looks like a straight line, that crosses the y-axis at y=1,

and slopes up from left to right with a slope of 1/2 .

If you mean: (5x+3)/(x+6) = 2 then the value of x is 3 because:

Multiplying both sides by x+6:-

5x+3 = 2x+12 => 3x = 9

Therefore: x = 3

The first thing to do is remove the coefficients of the side with the variable. This is done here by dividing by two, to give sin(2x) = 0.5. The next step is to remove the sine function; take the inverse sine of each side to give 2x = 30o (for degrees) or 2x = 0.5236 (for radians; equal to pi/6). Finally, remove the coefficient of x by dividing by 2 again. This gives 15o or 0.2618 (equal to pi/12). These are only the trivial solutions; all others can be found using predetermined formula.
