Distance from a v-t graph?
yes, if you have a graph with a line....take a look at the picture I linked. ok so the distance covered is simply the area of the graph. do you know how to calculate the area of unusual shapes like this one?? if you don't, you simply divide the shape into 3 parts: two triangles and the square. the find the area of each one and add them together. the area is measured in metres.
How do you find the area of a shape that is inside of another shape?
you simply find the area of all of the shape then - the white are(the shape inside)YOU MUST TAKE-AWAY FROM 360 degrees as this is the whole areaexample:a square is 17 bu 12 then take-away that from the shape insidehope this is what you are talking about
What is the relationship between square numbers and square roots?
The square root is the area in which you take 1 length and you multiply that number times the same number and you have your square root. The square you put it on graph paper and you size is going to be 3x3 then you connect the dots and count how may squares you have and that is your answer.There is an inverse relationship. If one number is the square of another then the second number is the square root of the first number.
How do you find the equation of a linear relationship from a graph?
y=mx+b means that m is the slope, x is the variable, and b is the y intercept.[ADDED] The gradient m is given by the difference formula [ y2 - y1) / (x2 - x1) ] where the 1 and 2 signify separate ordinates and the y-values are those from their corresponding x-values.NB: they are not powers or factors here, but the text editor's limits makes typing algebra difficult.In words, it is the change in the y-value given by a chosen change in the x-value.So if the equation is y = 3x, lets take the values of x as 1 and 4. Therefore, the slope = [ (12-3) / (4-1) ]= 9/3 = 3.Important: always take the 1 and 2 co-ordinates in that rising-x order, not necessarily smaller-from-larger in y, because if the graph slopes down to the right the y-difference will be a negative number so the gradient is negative, and that is its correct description.AS AN ASIDE because we need not complicate things by invoking calculus for simple linear graphs, that difference-over-difference formula in calculus notation is shown by the operator, dy/dx; and the process is called "differentiation". Worth recalling when you proceed to studying Calculus, which analyses non-linear equations!
What is the formula for finding an angle in a circle graph?
get a protractor, then multiply your decimal by 360 degrees. Then take that number and find it with the protractor.
IWhat shape does the graph of a linear relationship take?
Linear = Straight line! So, a graph of a linear relationship is a straight line.
What shape does the graph of a linear relationship take?
a line
What shape does the graph of a linear realationship take?
It's linear, so it's a line...
What shape does the grapg of a linear relationship take?
A straight line that goes through the origin.
What is a discrete and non-linear graph?
A discrete graph is one where one or both variables can only take a some values. These are usually integer values but need not be. For example, shoe sizes (in UK) go up in half units. A non-linear graph is one in which the points of the graph do not lie on a straight line.
Are linear equations and functions the same?
No. A linear equation is just one type of function.If you graph a linear equation, you get a straight line.A "function" on the other hand can take on many different forms: a straight line, a wave line (the sine function), a parabola, etc.No. A linear equation is just one type of function.If you graph a linear equation, you get a straight line.A "function" on the other hand can take on many different forms: a straight line, a wave line (the sine function), a parabola, etc.No. A linear equation is just one type of function.If you graph a linear equation, you get a straight line.A "function" on the other hand can take on many different forms: a straight line, a wave line (the sine function), a parabola, etc.No. A linear equation is just one type of function.If you graph a linear equation, you get a straight line.A "function" on the other hand can take on many different forms: a straight line, a wave line (the sine function), a parabola, etc.
How do we make a linear function?
Take a variable, x. Take any two constant numbers a and b. Then a*x + b is a linear function of x. It is called a linear function because if you draw a graph of a*x+b against x, you will get a straight line.
How are linear equations similar or different from functions?
A linear equation is a specific type of function that represents a straight line on a graph. While all linear equations are functions, not all functions are linear equations. Functions can take many forms, including non-linear ones that do not result in a straight line on a graph. Linear equations, on the other hand, follow a specific form (y = mx + b) where the x variable has a coefficient and the equation represents a straight line.
What is an example of a circuit that doesnt obey Ohms Law?
The easiest circuit that does not obey Ohm's law is a circuit that has a resistance that depends on temperature. For example, if you take a light bulb and draw a current-vs-voltage, you see that in the beginning (under low voltage) the graph is NOT a straight line, but under high voltage the graph is linear. This is because the resistance depends on temperature. the equation V=IR isn't consistent with the graph's shape.
What does it means The strength and direction of a linear relationship between two variables?
The direction of a linear relationship is positive when the two variables increase together and decrease together. The direction is negative if an increase in one variable is accompanied by a decrease in the other. The strength of the relationship tells you, in the context of a scatter plot of the two variables, how close the observations are to the line representing the linear relationship. There are various very closely related measures: regression coefficient or product moment correlation coefficient (PMCC) are commonly used. These can take any value between -1 and +1. A value of -1 represents a perfect negative relationship, +1 represents a perfect positive relationship. A value of 0 represents no linear relationship (there may be a non-linear one, though). Values near -1 or +1 are said show a strong linear relationship, values near 0 a weak one. There is no universal rule about when a relation goes from being strong to moderate to none.
What is Karl pearsons correlation co-efficient?
Pearson's correlation coefficient, also known as the product moment correlation coefficient (PMCC), and denoted by r, is a measure of linear agreement between two random variable. It can take any value from -1 to +1. +1 indicates a perfect positive linear relationship between the two variables, a value of 0 implies no linear relationship whereas a value of -1 shows a perfect negative linear relationship. A low (or 0) correlation does not imply that the variables are unrelated: it simply means a there is no linear relationship: a symmetric relationship will give a very low or zero value for r.The browser which we are compelled to use is not suited for any serious mathematical answer and I suggest that you look up Wikipedia for the formula to calculate r.
