Answer: It is the second graph. See the attached figure.

Explanation:

1) You can consider the function y = sin(θ − 2) as a transformation of the parent function y = sin θ

2) Subtracting a constant from the argument of a function leads to shifting the graph as many units to the right as the constant.

3) So, subtracting 2 from the argument of y = sin θ shifts its graph 2 units to the right.

4) Since the x-intercepts of y = sin θ in the interval 0 to 2π are 0, π, and 2π, the x-intercepts of y = sin(θ − 2) will be 2, π + 2, and 2π + 2.

5) The x-intercepts are not enough to differentiate between some graphs, so take into account the local maxima or minima.

The local maxima of the function y = sin θ in the interval 0 to 2π are at x = π/2, and 3π/2, then the local maximum of y = sin(θ − 2) is at π/2 + 2.

That is the second graph.

I attach the graph for avoiding confussions.

The answer is the second graphSOlution: y = sin(θ − 2) =>y = sin θ
Subtract y = sin θ in the interval 0 to 2π are 0, π, and 2π,
the x-intercepts of y = sin(θ − 2) will be 2, π + 2, and 2π + 2.
then the local maximum of y = sin(θ − 2) is at π/2 + 2.
SO it is the second graph.

A six-foot-tall person is standing next to a flagpole. The person is casting a shadow 1 1/2 feet in length, while the flagpole i

Answer: 20 ft

This problem can be solved by the Thales’s theorem, which states:

Two triangles are similar when they have equal angles and proportional sides

It should be noted that to apply Thales' Theorem, it is necessary to establish the two triangles are similar, that is, that they have the corresponding angles equal or that their sides are proportional to each other.

Now, if we measure the shadow of the flagpole and the shadow of the person, at the same moment, we can use the first Thales' Theorem to calculate the height of the flagpole, knowing the height of the person.

In this case we have two similar triangles (Figure attached) where $H$ is the height of the flagpole, $h=6 ft$ is the height of the person, $A=5 ft$ is the length of the shadow of the flagpole and $a=1\frac{1}{2}=1.5 ft$ is the length of the shadow of the person.
