Answer:
A
Step-by-step explanation:
One complete turn is 1 perimeter (aka circumference).
We have to find the length it turned, hence, its circumference.
The formula for circumference (C) of a circle is:
Where r is the radius
The radius is HALF of diameter. Given diameter is 250, the radius is:
r = 250/2 = 125 feet
Now, substituting in formula we have:
So, it turned 785.4 feet with 1 rotation.
The correct answer is A
Answer:
Step-by-step explanation:
First, find the slope using the points (3, 2) and (-1, -1):
Slope =
Find the y-intercept, b, by substituting x = -1, y = -1 and m = ¾ in y = mx + b.
-1 = ¾(-1) + b
-1 = -¾ + b
Add ¾ to both sides
-1 + ¾ = b
(-4 + 3)/4 = b
-¼ = b
Substitute m = ¾ and b = -¼ in y = mx + b.
The equation would be:

The coefficients of any row of Pascal’s triangle can be calculated using (A) combinations
<h3>How to determine the coefficients?</h3>A binomial expansion is represented as:
Where:
x >= 0 and x <= n
In the above expression, the coefficient is:
The above represents the xth term of a Pascal triangle and it is a combination expression
Hence, the coefficients of any row of Pascal’s triangle can be calculated using (A) combinations
