Answer:
The displac ment between t = 1 and t = 4 is 272 feet
Step-by-step explanation:
To get the displacement of the ball, we first need to get the equation for the position of the ball with respect to time.
We can do this by differentiating the velocity equation given:
v(t) = -32t +96
integrating between the limits of t = 1 and t = 4, we have
![s =[ -16t^2 +96t] t = 4, t =1](https://tex.z-dn.net/?f=s%20%3D%5B%20-16t%5E2%20%2B96t%5D%20t%20%3D%204%2C%20t%20%3D1)
where t = 4.
s = 256 + (96) =352 feet
Where t = 1
s = 80
Displacement of the ball = 352 -80 = 272ft
The displac ment between t = 1 and t = 4 is 272 feet
Answer:
I like A the best; B also works.
Step-by-step explanation:
Choices C and D do not result in centimeters, so are useless for this problem.
Though you can use the conversion factor 1 ft = 30.48 cm, I find it convenient to remember the conversion 1 in = 2.54 cm. The first factor with choice B gets you there:
... 1 yd = 3 ft = 3×30.48 cm = 91.44 cm . . . . . . can do in your head
As does choice A:
... 1 yd = 36 in = 36×2.54 cm = 91.44 cm . . . . . probably requires a calculator
The path you understand and that works for you is the "best" path.

Answer:Arrange the following measurements in order from smallest to largest.
0.35 kilogram, 5 gram, 9.4 gram
Step-by-step explanation:Kilograms (Kg) and grams (g) are both units of measurement for MASS quantity. However, these units are not the same as they vary in magnitude. The kilograms is bigger unit of measurement than the grams. 1000grams makes 1kilograms.
According to this question, 0.35 kilograms 9.4 grams and 5 grams are to be arranged in ascending order i.e. from smallest to largest. First, we need to change all the units to the same.
We change 0.35kg to g
Since 1000g = 1kg
Then, 0.35kg = 0.35 × 1000
= 350g.
Rearranging the values, we have:
5 grams < 9.4 grams < 0.35 kilograms
