Answer: The volume is decreasing here .
The rate of change = -0.25
Step-by-step explanation:
Given: In a graph , coordinate plane with x-axis labeled Number of Hours and y-axis labeled Volume in Liters.
The graph of a line contains the points: (1, 2) and (3, 1.5)
From the points, change in volume = change in y
⇒ Change in volume =
Change in time = change in x
⇒ Change in hours=
The rate of change for a graph is given by:-
Since, the rate of change is negative , therefore, the volume of water decreases.
Answer:
a
Step-by-step explanation:
The maximum height occurs at the vertex found using t = -b/2a
Solve for t
t = -20 / 2(-5) = -20/-10 = 2 seconds.
Now replace t with 2 in the original equation to solve for the height:
h(t) = -5t^2 + 20t + 110
h(2) = -5(2)^2 + 20(2) +110
h(2) = -5(4) + 40 + 110
h(2) = -20 + 40 + 110
h(2) = 130
Travis only threw the spike 130 meters. Since Laura is at 135 meters, the spike did not reach her.
Answer: 48m2 + 56m
Step-by-step explanation:
Hey there! :D
If you divide both sides by 9:
9/9=1 36/9=4
1:4 is equivalent.
I hope this helps!
