The answer is -|0.35 t -14| +14
<u>Step-by-step explanation</u>:
The problem statement is asking for an expression for distance in miles, so the constants in the expression will be miles. In the time it takes to get to point B (40 minutes), the ferry has gone (0.35 mi/min)×(40 min) = 14 mi. Hence the maximum value of the function must be 14. The only function with that characteristic is the one of selection D.
Answer:
(c) (-3, 0) and (-5, 0)
Step-by-step explanation:
The given coordinates are -3 -(-5) = 2 units apart on the horizontal line y=-2.
Then the needed coordinates will be on the vertical lines x=-5 and x=-3, and will have y-coordinates that are different from -2 by 2: either -4 or 0.
The points that meet these requirements are (-3, 0) and (-5, 0).
