Answer:
20x-8y+ 7/20
Step-by-step explanation:
Answer: It represents decay.
Step-by-step explanation:
Because 0.5 is less than 1, it is constantly decaying because multiplying by a fraction of a number gives you less than what you started with.

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
x + (3x - 4) = 5 - (-7 - 3x)
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Distributive Property] Distribute negative: x + 3x - 4 = 5 + 7 + 3x
- [Addition] Combine like terms: 4x - 4 = 12 + 3x
- [Subtraction Property of Equality] Subtract 3x on both sides: x - 4 = 12
- [Addition Property of Equality] Add 4 on both sides: x = 16
0.000701 in notation is 7.01 x 10^-4
The number has to be greater than 1 but less than 10. If the number is small then the exponent will be negative. 7.01 is less than 10 and greater than 1. In order to get the number you go to the right 4 times.

Answer:
v (E) = √(2E/m)
Step-by-step explanation:
From the question given:
E = ½mv²
E is the kinetic energy
m is the mass of object
v is the velocity.
To find a model v(E) for the velocity of the object, we simply make V the subject of the above equation.
This can be obtained as follow:
E = ½mv²
Cross multiply
mv² = 2E
Divide both side by m
v² = 2E/m
Take the square root of both side
v = √(2E/m)
Therefore, the model v(E) for the velocity of the object is given by:
v (E) = √(2E/m)
