The points have the same x-coordinate, so they lie on a horizontal line. The distance between them is the difference between their y-coordinates.
The distance between the two points is 1.3.
The distance between the two points is 1.3.
Answer:
≈23.6 kg left.
Step-by-step explanation:
For determining this, we can simply use an exponential decay equation representing this scenario:
a: the initial amount
t: the amount of time
h: the half life
Now, substitute the numbers into the equation:
Now, solve this equation:
Use a calculator to solve for y:
y= 200(0.118)
y≈23.6 kg left.
