Step-by-step explanation:

On a unit circle, the sine value is the y-coordinate and the cosine value is the x-coordinate.

Therefore, the coordinates for 30° on a unit circle would be:

(cos 30°, sin 30°)

=

answer: 0.64

step-by-step explanation:

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.
