function f is an exponential function. it predicts the value of a trading card, in hundreds of dollars, as a function of the number of decades since it was last purchased.

what equation models this function?

Step-by-step explanation:

Given graph models a function f which is an exponential function.

We know that the exponential function is given by  

, b is the rate of change and x is the time period.

In the given graph we see two points as (0,4) and (1,7)

Now, put x=0 and y=4 (for first point) in the exponential  function such that

Put x=1, y=7 and A=4 (for second point) in the exponential  function such that

Now substitute A=4 and b=1.75 in the standard exponential function we get our equation that models the given function that predicts the value of a trading card, in hundreds of dollars (y)

, where x is the number of decades.

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !

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
