Answer:
we select all the points apply to the given situation:
(a)The balloon falls at a rate of 50 ft per minute.
(b)The y-intercept is 1000 ft.
(c)The balloon begins to from an initial height of 1000 ft.
(d)It will take the balloon 20 minutes to reach the ground.
(e)The slope is -50 ft per minute.
Step-by-step explanation:
We have given,
Two points (0,1) and (2,4).
Slope of line passing through these two points is:
Slope = [tex]\frac{4-1}{2-0} =\frac{3}{2}[/tex]
Next,
A balloon begins its descent to the ground at 1000 ft above the ground.
that means y intercept = 1000 ft
And Balloon falls at a rate of 50 ft per minute.
Time taken to reach the ground = [tex]\frac{Height}{rate}[/tex] = [tex]\frac{1000}{50}[/tex] = 20 minutes
Since the balloon is falling down so the distance along y axis will decrease. Hence the slope will be negative and equal to - 50 ft per second
Now we select all the points apply to the given situation:
(a)The balloon falls at a rate of 50 ft per minute.
(b)The y-intercept is 1000 ft.
(c)The balloon begins to from an initial height of 1000 ft.
(d)It will take the balloon 20 minutes to reach the ground.
(e)The slope is -50 ft per minute.
