Answer:
Step-by-step explanation:
if cot=3/4 and the terminal point determined by is in quadrant 3, then ... cos ((3\pi )/(4)) ... The angle of elevation to the top of a 20-story skyscraper is measured to be 2 ... If the point P(-4/5,y) lies on the unit circle and P is in the third quadrant, what does y equal ...... if z1=5+5i and z2=8(cos(3pi/7)+isin(3pi/7)) then z1 z2=____?

Answer: tis C
Step-by-step explanation:
x^2/x^2*z^2/y^-2
=1*z^2/y^-2
=z^2y^2
=y^2z^2
Let's rewrite the mathematical expressions:
3 1/6 = 3.166666667
1 5/6 = 1.833333333
Subtracting both expressions we have:
3.166666667- 1.833333333 = 1.727272727
