Let h(z) =-x log2(x) _ (1-x) log2 (1-2), where 0 〈 x 〈 1. )loog
(a) what is the global maximum of h(x)?
(b) interpret part (a) in terms of the uncertainty in tossing a (possibly biased) coin.

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.

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

m∠a is 90°

m∠b is 40°
