22/21

Step-by-step explanation:

So we multiply 5 by 3, and get 15, then we multiply 7 by 3 and get 21.

Do the same for the second term. We multiply 1 by 7, and get 7, then multiply 7 by 3 and get 21.

ince our denominators match, we can add the numerators.

15 + 7 = 22

So the answer is:

22/21

22/ 21

Step-by-step explanation:

5 × 3 = 15

7 × 1 = 7

15 + 7/ 21

= 22/21

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
