Answer:
Step-by-step explanation:
From the given information:
The diagrammatic interpretation of what the question is all about can be seen in the diagram attached below.
Now, let V(x) be the time needed for the runner to reach the buoy;
∴ We can say that,
In order to estimate the point along the shore, x meters from B, the runner should stop running and start swimming if he want to reach the buoy in the least time possible, then we need to differentiate the function of V(x) and relate it to zero.
i.e
The differential of V(x) = V'(x) =0
=
squaring both sides; we get
By cross multiplying; we get

Plot your first point at 1 on the y-axis and then go up 4 and right once each time
All this means is (f(x)) + (g(x))
2x-1+ x^2-3x-2=
=== x^2 - x -3
Answers:
scalene (column 1)
right triangle (column 2)
==============================================
Explanation:
The lack of tickmarks tells us indirectly that none of the sides are equal to one another. So all three sides are different lengths. Therefore, the triangle is scalene. This rules out "equilateral" and "isosceles".
The small square marker indicates we have right angle, aka 90 degree angle. In turn, it leads to the fact we have a right triangle. This rules out "acute" because acute triangles have all three angles smaller than 90. We can also rule out "obtuse" because obtuse triangles have one angle larger than 90.
In short, this triangle is both scalene and a right triangle. We can call it a right scalene triangle, or a right triangle that is scalene.
