How can you tell by looking at the graph of a function that it is nonlinear?
A linear function would be represented by a straight line graph, so if it's not a straight line, it's nonlinear
How can a line be linear and nonlinear?
Two possibilities: The line is linear over some of its length and then goes non-linear (or the other way round: Think of a mass, at the end of a string, being swung in a circle. Then the string is cut. The motion of the mass would have been circular (lon-linear) until the instant the string was cut and then linear, as it flies off into a tangent. Or The line is linear from one perspective but not from another: Think of the trajectory of a ball that is thrown up at an angle to the horizon. If seen from above, the ball travels in a straight line (linear) but if seen from the side it follows a parabola (non-linear). Hope that helps.
Is y 5 2x a linear equation?
I'm not exactly sure what the equation is supposed to be, but it looks like there are no variables, x or y, that have a power, squared, cubed, etc., so the equation would be linear. As soon as you put a power into the equation it becomes nonlinear.
How many tons per linear meter of steel?
That would depend on the cross sectional area of that linear meter of steel and as you have not told us that we can not answer you. To work out the answer for yourself you need to know the VOLUME of your steel and you multiply this by the density of your steel to give you a weight.
What is the difference between linear and nonlinear?
Ans:when two quantities depend on each other (like speed and distance), then when an amount increase in one quantity causes a corresponding amount increase or decrease in the other quantity that is the same regardless of the value at which the measurement was taken, then that's linear.Sounds a big horrible.OK, if you drew a graph of one quantity against another, it would form a straight line, and we say it increases or decreases (depending on whether the graph is increasing or decreasing) linearly. it means in creases with a power of 1, with a common ratio for increasing values of x.OK, what if it was y= ax^2? This is not linear, because it increases with a power of 2.A linear line takes the form y = mx +cwhere m is the ratio and c determines the point the graph cuts the x=0 line.
