Which strategy best explains how to solve this problem? Rebecca bought a meal and two snacks for lunch each day. The meal cost $
Fittoniya [83]
Given:
Cost of lunch per day = 1 meal and 2 snacks

C = 5.5 + 2(0.75) = 5.5 + 1.5 = 7

7 * 12 days = 84

Based on the choices, the best strategy would be:

<span> A. Make a table. Write the numbers 1 to 12 in the top row of the table (the number of days). In the first box on the second row, write $7. This is how much Rebecca spends in 1 day. In each of the next boxes in the second row, write the amount Rebecca spends by adding $7 to the previous amount. The answer in box 12 is the total amount Rebecca spent after 12 days.</span>

Rewrite −1 + 2i in polar form.
raketka [301]
The length of the radius would sqrt(1+4), or sqrt(5).
                                                                                           2
The angle would be in Quadrant II and would be arctan ------ , or arctan (-2).
                                                                                           -1

Find this angle using a calculator or table.

Then you end up with -1+2i = sqrt(5) angle arctan(-2).  The angle would be + and measured from the + horizontal axis.
