If f(x) = , find f ''(1).

f ''(1) =

27/64 or any other equivalent form

Step-by-step explanation:

using quotient rule

f'(x) = =

using quotient rule again

f''(x) =

simplifying to make it easier to plug in

f''(x) =

=

=

=

f''(1) = =

answer: 20

step-by-step explanation:

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
