Douring a recent snowstorm, john measured the total snowfall accumulated at the end of each hour. he recorded his results in the table below time snowfall total 1 p. m. 2 p. m. 3 p. m 4 p. m. 5 p. m. 6 p. m. (in inches) 0.7 1.9 2.8 3 8 4.3 5.1 what is the approximate average rate of change of the snowfall between 1 p. m. and 6 p. m.? ! !

The answer is B

Step-by-step explanation:

If you add up all the changes in each hour and divide it by the 5 hour difference the average you get 0.88 so you round to 0.9

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
