Trigonometry question Suppose for some acute angle, sin θ=0.345. Use the unit circle definition of trigonometry (no inverse functions) to find:
sin(π+θ), sin(2π-θ), and sin(π-θ)

people went from manufacturing one object at a time by hand to manufacturing many objects in factories

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
