Hi there!
v = ±
- - - - - - - - -
K = 1/2mv²
Isolate for the variable "v". We can begin by dividing both sides by 1/2. (Multiply by the reciprocal, or 2):
2 · K = 2 · (1/2mv²)
2K = mv²
Continue isolating by dividing both sides by "m":
2K / m = v²
Take the square root of both sides. Remember that the solution can either be positive or negative since there are positive and negative roots.
v = ±
Answer:
4
Step-by-step explanation:
First, solve in the brackets,
-3+(-1)
-3-1
-4
Since it is absolute value, take the minus sign away,
therefore the answer is 4
The point lies directly on the regression line.
Answer:
To find the scale, multiply the measurements by the factor.
Step-by-step explanation:
You can use the expression: New Salary = (120/100) * X
You could also simplify 120/100 to 6/5
