Solving trig antiderivatives usually involves breaking the integral down to apply Pythagorean Identities, and them using a

-substitution. That's exactly what we'll do here.

The most reasonable estimate for 90 days is B. 2 × $10^{6}$ meals.

Explanation:

The given values are A. 2 × $10^{7}$ , B.2 × $10^{6}$ , C.2 × $10^{-7}$ , D.2 × $10^{-6}$ . All the given values are in the range of 2 so it will only logical if we round off the value we have too. We round off 1,633,500 to 2,000,000.

Suppose you multiply 2 with 100 you get 100, 2 multiplied with 100 is represented by 2 × $10^{2}$ so the power to which 10 is raised represents the number of zeros in the resulting value i.e. 10 is raised to the power of 2 so the resulting answer has 2 zeroes.

Options C and D have negative powers so they will equal decimal values so only options A and B could be the answer. Since there are 6 zeroes in 2,000,000 which is equal to 2 × $10^{6}$ . So the answer is option B.
