15 ! me figure this out i am so confused

  10a.  439

  10b.  1253

  11a.  linear

  11b.  $37.23

Step-by-step explanation:

10. Put the numbers in the equation and do the arithmetic. For logarithms, a scientific or graphing calculator will be required. The first attachment shows the result for 2 years = 24 months.

  920log(3) ≈ 439 . . . after 4 months

  920log(23) ≈ 1253 . . . after 2 years

___

11. Your experience with taxis tells you the fare is usually based on time and distance and some fixed charge. That is, it is roughly linearly related to distance. Plotting these data points will tell you the same thing: a linear model is suitable.

A graphing calculator or spreadsheet (or any of several web sites) can help you calculate the regression model. The second attachment shows my result:

  fare ≈ $2.10 + 3.513×miles

So, for 10 miles, the expected fare is ...

  $2.10 + 3.513×10 = $37.23

Comment on these problems

It is useful to learn to use your calculator's various functions. That can save you a lot of effort and angst.

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
