Answer:

10 km/h  

Step-by-step explanation:

Let s = man's speed and c = speed of current

    s + c = 15

         c = 2.5     Insert value of c

s + 2.5 = 15        Subtract 2.5 from each side

        s = 12.5 km/h

=====

Speed against current

= 12.5 – 2.5

= 10 km/h

What is the relative minimum of the function? <br> if anyone could help it would be appreciated!! :)
AleksandrR [38]

Answer:

-2

Step-by-step explanation:

since the parabola opens upwards, the minimum is at the vertex of the parabola and the maximum is infinity, because the lines of a parabola goes on forever

you look for the smallest x value for the parabola and since you can see that the vertex of the parabola lies on x=-2, the minimum value of the function is -2.

Hope that helps :)
