Answer:
25
Step-by-step explanation:
The number that needs to be added is the square of half the x-coefficient:
(-10/2)^2 = 25
_____
Adding that gives ...
(x -5)^2 = 32
x = 5 ± 4√2
Answer:
x = 21/8
Step-by-step explanation:
So 8 is being multiplied by something to get to 21
So 8x = 21
Solve for x:
-Chetan k
Answer:
Maybe B?
Step-by-step explanation:
Answer:
= 5.785 × 10⁶
Step-by-step explanation:
5,785,000
= 5.785 × 10⁶
The formula for the velocity, v is √2E/m
<h3>What is kinetic energy?</h3>
Kinetic energy is half the mass multiplied by the square of the speed of the object
It is written thus;
Kinetic energy = 1/ 2 × m × v²
To solve for 'v' mean that we should make 'v' the subject of formula
E = 1/ 2 mv²
E = 
cross multiply

To make 'v' the subject, we have

Thus, the formula for the velocity, v is √2E/m
