Explain why h = -3(t 2– 4t – 5) is equivalent to the original equation, h(t) = -3t^2 + 12t + 15 *
Your answer

it is because after you expand h=-3(t2-4t-5) you will get h(t)

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
