Answer:
2.3 by 10^7
Step-by-step explanation:
We want this rewritten in the form 2.3*10^n.
To get the decimal point in 23,000,000 between the 2 and 3, we must move it 7 places to the left, and then compensate for this by multiplying 2.3 by 10^7.
Answer: If you are asking which one is larger then it is 3/4
Step-by-step explanation: 3/4 is larger than 2/3
The given curve crosses the x-axis whenever x is a multiple of π, and it lies above the x-axis between consecutive even and odd multiples of π. So the regions with area S₀, S₁, S₂, ... are the sets
and so on, with
for natural number k.
The areas themselves are then given by the integral
Integrate by parts twice. Take
so that
then
so that
Overall, we find
or
Using the antiderivative and the fundamental theorem of calculus, we compute the k-th area to be
Since , the sum we want is a convergent geometric sum. As n goes to ∞, we have
