Which expression is equivalent to 3cos2(StartFraction theta Over 2 EndFraction) minus 3? Three-halves(cos(ϴ) – 1)
Three-halves(cos(ϴ) – 5)
3(cos(ϴ) + 2)
3(cos(ϴ) + 1)

It's a 3/2(cos(O)-1

Step-by-step explanation:

I plugged all the equations in desmos and that was equal to the given equation.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
