What type of model should be used to make a prediction from the given data? (0,2), (1,5), (2,6), (3, 5), (4, 3). linear cubic square root quadratic

Answer with explanation:

When you will plot the points in x y plane,

And find the slope between any two points that is , ratio of difference of any two y values to any two x values the ratios are not same.So, the model is not Linear.

And when you will join all these points,as all points lies in first quadrant,so if you will join them, and produce it from both ends, it will cut X axis at two points only. The model can't be cubic also,due to the fact that it has only two zeroes,and it cuts the x axis twice only, also it can't be square root of any function,then it would have only one zero.

So , the Model is Quadratic.

step-by-step explanation:

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
