1 kilo=1000 meters
so
216 kilo=216 000 meters
Answer:
2401
Step-by-step explanation:
because 7*7*7*7=2401
D. Have the same number of valence electrons
I think you are suppose to get "k" by itself, so you first multiply 2/5 to (k - 2)
-8 ≤ 2/5 (k - 2)
-8 ≤ 2/5k - 4/5
Next you add 4/5 on both sides
-8 + 4/5 ≤ 2/5k
Then you make the denominators the same in order to add them
-40/5 + 4/5 ≤ 2/5k
-36/5 ≤ 2/5k
Finally you multiply each side by 5/2 to get "k" by itself
-18 ≤ k
Answer:
See below
Step-by-step explanation:
Answer choices:
1. The potato was launched from the ground.
-
False. 20 feet above the ground
2. The flight is symmetric about the line t = 2.
-
False. Line of symmetry is t=3
3. The potato reaches a maximum height of about 3 ft
-
False. Maximum height is about 150 ft
4. The potato is in the air during the interval 0
- Unclear. no interval given
5. The potato reaches its maximum height after about 3 seconds in flight.
6. h(2)=h(5)
- False. h(2) = 140 ft, h(5) = 80 ft
