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.
