14. what is the center and radius of the circle that has the equation (x + 7)^2 + (y - 4)^2 = 49? explain.

Explanation:

In this circle equation, all the negative symbols give you the OPPOSITE TERMS OF WHAT THEY REALLY ARE, so first off, taking the square root 49 will give you a radius of 7 units, and the centre of the circle will be

I am joyous to assist you anytime.

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
