The traveled distance is 40.819 feet (downward)
Answer:
Domain: T, from 0~80
Range: W, from 500~2500
Step-by-step explanation:
W = 25T + 500
T(Time) is from 0 to 80
So W(Water) is
When T = 0, W = 25*0 +500 = 500
When T = 80, W = 25*80 + 500 = 2500
Answer:
Below in BOLD.
Step-by-step explanation:
h(t) = -0.2t^2 + 2t
We can find the maximum height and the time by converting to vertex form:
h(t) = -0.2(t^2 - 2t)
= -0.2[(t - 1)^2 - 1)
= -0.2(t - 1)^2 + 0.2
The time to get to maximum height = 1 second and the maximum height is 0.2 m.
When the ball reaches the ground h = 0 so
-0.2(t - 1)^2 + 0.2 = 0
(t - 1)^2 = -0.2 / -0.2 = 1
t - 1 = 1
t = 2 seconds.
Here's the graph.
The vertex is at (-3, 3), and it goes through points (-2, 2), (-4, 2), (-1, -1), (-5, -1).
Answer:
Jose incorrectly rounded $2.85 down to $2. The estimate should be $18.
Step-by-step explanation:
When we round 6.2 lb to the nearest pound we round down, because the digit after point is less than 5 (2<5), so

When we round $2.85 to the nearest dollar we round up, because the digit after point is greater than 5 (8>5), so

Now, 6.2 lb of blueberries will approximately cost

Hence, Jose incorrectly rounded $2.85 down to $2. The estimate should be $18.
