Question

Archers need to use arrows that do not bend easily. Th e table shows how the weight of an arrow affects its spine, or the distance the center of the arrow bends when a certain constant weight is attached. Graph the data in the table to find a linear and a quadratic model for the data. Use the regression feature on your calculator to find each model. Which model is a better fit? Explain. weight (in grams) 140,150,170,175,205 weight (in inches) 1.4,1.25, .93, .78, .43 I got for quadratic a=.000057 b=-.034779 c= 5.17175 for linear i got m=-.015206 b=3.51253 what do I do now?

Answer 1

you have the coefficients for the models:

y = ax^2+bx+c
or
y=mx+b

sounds like you need to review more than just which buttons to push.
