1 – sin 2x

cos 2x

sin 2x

The given expression is sin x cos x. Using the identity sin 2x = 2 sin x cos x, we can rewrite the expression as 2 sin x cos x. Therefore, the correct answer is sin 2x.

Explanation

The given expression is sin x cos x. Using the identity sin 2x = 2 sin x cos x, we can rewrite the expression as 2 sin x cos x. Therefore, the correct answer is sin 2x.

6. SOAL

31

21

16

15

The given sequence of numbers follows a specific pattern. Each number is obtained by subtracting a decreasing number from the previous number. For example, 31 - 3 = 28, 28 - 7 = 21, 21 - 5 = 16, and 16 - 1 = 15. Therefore, the next number in the sequence would be obtained by subtracting 1 from 15, resulting in 14.

12. Misal titik C berada di antara titik A(3, 5, 7) dan B(6, - 4, - 11) dengan AC : CB = 2 : 1. Dengan demikian maka koordinat titik C adalah ....

( 5, -1, 5 )

( 5, -1, -5 )

( 4, 2, -1 )

( 0, 2, -1 )

( 1, -3, 4 )

The coordinates of point C can be found by using the concept of section formula. According to the given information, AC:CB = 2:1. This means that the ratio of the distances AC and CB is 2:1. By applying the section formula, we can find the coordinates of point C. The x-coordinate of C is found by taking 2/3 of the difference between the x-coordinates of A and B. Similarly, the y-coordinate of C is found by taking 2/3 of the difference between the y-coordinates of A and B. And the z-coordinate of C is found by taking 2/3 of the difference between the z-coordinates of A and B. By calculating these values, we get the coordinates of point C as (5, -1, -5).
