Maths B Assignment

Preamble: Earlier this year, during term 3 in our intents contribute we had conducted an investigation to find that a thumpings doing fits a parabolical wait on. frankincense the analysis procedure testament be easier through with(p) with a quadratic regression analysis. Aim: The aim of this appellation is to look into the rate of change on a ball parabolic as it moves up and down an inclined plane. in unioniseation: time (sec)| distance (m)| 0| 3.9| 0.5| 2.6| 1.0| 1.7| 1.5| 1.1| 2.0| 0.9| 2.5| 1| 3.0| 1.5| 3.5| 2.2| 4.0| 3.4| 4.5| 4.8| Table 1.1: Balls Data The spare-time occupation data in Table 1.1 was given to me by my teacher. icon: fountainhead 1 (a) The tucker out the points shown in in writing(p) record 1.1 I move the data from Table 1.1 into a TI interactive inclination of an orbit and plotted and XY spread out plot. As notify be seen, Graph 1.1 shows that the graph follows a parabolic head. Hence it can be mo deled to the form y = ax2 + bx + c. (b) Graphs Regression Below graphs 1.2 is the regression of the balls motion that is shown in Q1.a. To find the regression I used the stat slowness function in TI interactive to find the equality of the motion and therefore putting that equation onto the graph. The equation of the function is, y = .7x2 2.9x + 3.9. is a professional essay writing service at which you can buy essays on any topics and disciplines!

After doing the stat calculation it is found that the regression suits the plot. Question 2: (a) To find the burn I am development the sunburn Function in TI Interactive. This wreak is shown below. To get at the specific points that I wanted I had to click on the tangent button in GRAPH ! on TI Interactive and then choose the value of x that I wanted in the box that is labelled with x. This is shown in motion-picture show 1.1. Image 1.1: Tangent Process Show Label The x value To calculate the careen I ticked that says SHOW mark to show the equation of the tangent. This to a fault means that the tangent follows the equation y = mx + c. Therefore the slope will be the value of m. Through this process I can find the slope of ten...If you want to get a abundant essay, order it on our website:
