Let a ∈ r n×n be a symmetric positive definite matrix and b ∈ r n. define f : r n → r by f(y) = 1 2 y t ay − b t y. show that f is strictly convex. conclude that f has exactly one global minimum. (recall that strict convexity alone does not guarantee that a global minimum exists.)

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
