The equation he uses to model the height of the rocket in cm, as function of time is
h(t) = -490 t^2 + 1120t
We can plot this equation using a graphing tool
Please, see attached picture
The rocket reaches his maximum height (640 cm) at
t = 1.143 s
Answer:
The total weight would be 5 lbs 12 oz.
Step-by-step explanation:
First, combine the ounces:
13 + 15 = 28 ounces
Next, convert that into pounds and ounces.
28 oz = 1 lb + 12 oz
Finally, add the weight back to the 4 lb.
1 lb + 4 lb + 12 oz = 5 lb + 12 oz
Answer:
The equation would be 6^ + b^ = 15^
First we bring each number to the power of two, 6^ = 36, and 15^ = 225
Then we subtract 36 from 225 and we get 189.
Then we "Square root" 189 because of the 2nd power on top of B
The correct answer is 13.8
I hope this helps :)
