Answer:
This test batch can be chosen in 2380 ways
Step-by-step explanation:
The order in which the batteries are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

In how many ways can this test batch be chosen?
4 batteries from a set of 17. So

This test batch can be chosen in 2380 ways
Use sin to calculate. Sin30=5/x. Sin=opposite/hypotenuse. Cross multiply. Sin30x=5. x=5/sin30. x=10.
Answer:
cos(π/6)= radical 3 over 2 sin(π/6) = 1/2
Step-by-step explanation:
In the unit circle the coordinates of the point for the particular angle can be expressed by cos(x) for the x value and sin(x) for the y value. For π/6, the point's x value is radical 3 over 2 as expressed by cos(π/6) and the y value is 1/2 as expressed by sin(π/6)
