V^2 = u^2 - 2gh; where v is the final speed, u is the initial speed, g = 9.8 m/s = 0.54 ft/min is the accerelation due to gravity, h = height.
At the maximum height, the final speed is 0.
u^2 = 2gh = 2 x 0.54 x 36 = 38.58
u = sqrt(38.58) = 6.21 ft/min
Therefore, the stne should be thrown with 6.21 ft/min
I believe it's E.) 12.96
12 times 8% equals .96 so $12.96 should be the answer since it wants the final price with tax :DD
Sorry, but I don't under stand what you are talking about.
This question uses the concept of the division.
Vivi, the band drummer, burns 765 calories in 3 hours. And she burns these calories at the same rate. Which means she burns the same amount of calories per hour.
Thus, the set up equation for this question will be:
Energy burnt in 3 hours=756 calories
Therefore, Energy burnt in 1 hour =
Calories.
Thus, the required answer is that Vivi burns 252 Calories of energy per hour while drumming.
Answer:
A
Step-by-step explanation:
It's hard to see but when x is 6, y is 4.5. Just plug that into each equation and see which one is correct.
![x^{2} =8y\\x=6;y=4.5\\6^{2} =8(4.5)\\36=36](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D8y%5C%5Cx%3D6%3By%3D4.5%5C%5C6%5E%7B2%7D%20%3D8%284.5%29%5C%5C36%3D36)
