At which values in the interval [0, 2π) will the functions f (x) = 2cos2θ and g(x) = −1 + 4cos θ − 2cos2θ intersect?

-1, -2, -3, -4, -6

step-by-step explanation:

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
