Answer:99.7
Step-by-step explanation:
Answer:
The energy in object is 3.8 Kilo Joules.
Step-by-step explanation:
We are given the following in the question:
Mass = 20 kg
Height,h = 20 m
g=9.5 m/s^2
Formula:
Potential energy =

Putting value we get,

Thus, the energy in object is 3.8 Kilo Joules.
Its 14.
30-40 is 11, 28-29 is 2, and 41 is 1.
Answer:
The domain of this function: (-∞,∞), or {x|x∈ℝ}
The range of this function: (-∞,∞), or {y|y∈ℝ}
Answer: y=
s=-30+10t
Step-by-step explanation:
9x + 2y = 5; y
9x-9x+2y = 5-9x
2y=5-9x
y=
1/15s - 2/3t = -2; s
(1/15s - 2/3t = -2)*15 ==> Get rid of fraction by multiplying both sides by 15
s - 30/3 t=-30
s-10t=-30
s=-30+10t
