Which of the following functions is graphed below?
1 answer:
The correct answer is A.
Since all of the functions in this problem are exactly the same, all we are looking for is the proper "greater than" and "less than" signs.
The first part of the equation, represented by x^3 - 3 ends at 2. You'll notice that it ends in a closed dot. This means we must use a rather than a <. The equals bar always goes below the sign when it is a closed dot.
The opposite is true for the second part, which includes an open dot. This means we must use a > instead of a .
Since A is the only one that has those as choices, it is the correct answer.

Answer:
Width of river = 0.25 mile
As length of river is not given , but it is given that campsite is located 1 mile east upstream, So length of river = 1 mile
Speed of mine in river while going upstream = 3 miles per hour
Speed of current as going Upstream = 1 miles per hour
Now Reduced speed of mine = Speed of mine in river while going upstream - Speed of current as going Upstream
= 3 - 1
= 2 miles per hour
1. There are two ways to reach campsite
(a) either walk 1 mile from starting point in east direction and then swim 0.25 mile in North direction to reach campsite.
Or
(b) From the starting point Considering a right triangle having, base=1 mile and altitude = 0.25 mile, then finding the length of hypotenuse using formula =
=
=√1.0625
=1.03078(approx)
⇒ you must walk a distance of 1 mile in the east direction and then swim 0.25 mile north direction to reach directly at campsite.[shown in the diagram]
