find the amount accumulated in an account after $9000 is invested for 8 years at a 4% coumpounded monthly

Step-by-step explanation:

9000(1+0.04/12)^(8*12)

9000(1.0033333)^96

9000(1.3763)

A=12,387.56

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
