Jane is going to drive her boat 8 miles at a planned speed of 6 miles per hour. She will be running upstream which will decrease
her speed by r miles per hour. r represents the speed of the river.
Her time t, in hours is a function of the speed of the river, r, in mph,
and is modeled below.

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

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.

step-by-step explanation:

you first to choose the points and then move from then as the slope you have
