0.60 × collection = 27 cars
collection = 27 cars / 0.60 . . . . divide by the coefficient of the variable
collection = 45 cars
Samuel has 45 cars in his collection.
Answer:
Step-by-step explanation:
The <em>average rate of change</em> of the function y = cos(2x) over the interval (0, π/2) is
The <em>average rate of change</em> over a given interval is defined thus :
- Where a and b are the interval values
<u>At a = </u><u>0</u><u> </u><u>:</u><u> </u>
- f(0) = cos(2(0)) = Cos 0 = 1
<u>At b = π/2</u> :
- f(π/2) = cos(2(π/2)) = Cos π = - 1
Hence,
Therefore, the <em>average rate of change</em> over the interval is
