The relationship between the rates of change can be found by taking the derivative of area with respect to time.
... a(t) = π·r(t)²
... a'(t) = 2π·r(t)·r'(t)
At the time of interest, we have
... a'(t) = 2π·(6 ft)·(5 ft/min) = 60π ft²/min
The rate of change of area at that time is 60π ≈ 188.5 ft²/min.
Distribute the negative to the 16 and into the -5
-16+5x
615-138 = 477 you start with 615 take away how many pens are left and then you get your answer
Are you asking to find the difference?
Answer:
B
Step-by-step explanation:
Using the Pascal's triangle
Pertaining to the 8th term the coefficients are;
1, 8, 28, 56, 70, 56,28, 8 and 1 in that order
Expanding this,
the coefficient of the term x^7y is 8
