A has coordinates (-2,-5) what is A' after a Dilation with a scale factor of N = -3.

A' = (6, 15)

Step-by-step explanation:

We consider the center point of dilation to be the origin (0,0)

so  point A(-2, -5)  to A'  by scale factor N = -3 means

A' = (-2*(-3),  -5*(-3)) = (6, 15)

hope it you

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
