A kayaker needs to paddle north across a 100-m-wide harbor. the tide is going out, creating a tidal current that flows to the ea
Scilla [17]
The velocity or speed of the kayaker going north at a speed of 3 m/s and that of the current going east at a speed of 2 m/s create a resultant speed of √13 m/s. The new distance that has to be traveled by the kayaker in order to move 100 m north is calculated through the equation,
                            3 / √13 = 100 / x 
The value of x is 120 m. The total time it will take for the kayaker to reach the destination is,
                                 t = 120 / √13 = 33.33 s

What is the slope of the line that passes through the points (-3, 1)(−3,1) and (7, -14) ?(7,−14)?
levacccp [35]

Answer: The answer for both is infinity. You might want to recheck the question as it is not very common but if the question is correct this is the answer to it:

Step-by-step explanation:

1. Using the formula m = y2 - y1 / x2 - x1

m = 1 - 1 / -3 -(-3)

m = 0/0

m = infinity

2. Using the formula m = y2 - y1 / x2 - x1

m = -14-(-14) / 7-7

m = 0/0

m = infinity.
