Answer: B
Step-by-step explanation:
100 feet every 2 minutes
100 divided by 2 is 50
50 ft per minute

Answer:
A= 20,58m²
Step-by-step explanation:
the side opposite to what is worth 6m is the diameter of the half circle to the left. I calculate the circumference of the circle (diameter multiplied by π), so 6 × π = 18.84
since the circumference is not whole but only half, we divide the result in half: 9.42 (the length of the half circle).
formula for the area of the rectangle: base multiplied by the height all divided by 2: (10×6)/2= 30m²
we subtract half the circumference: 30-9,42=20,58m²
The permutation equation is true for all integers n ≥ 3
<h3>How to prove the equation?</h3>
We have:
Apply the following permutation formula
So, we have:
Evaluate the difference
Expand
Multiply through by (n - 3)!
Expand
Divide through by n!
Take the LCM
Evaluate the like terms
Both sides of the equations are the same.
Hence, the permutation equation is true for all integers n ≥ 3
