A regular dodecagon P_1 P_2 P_3 \dotsb P_{12} is inscribed in a circle with radius 1. Compute
(P_1 P_2)^2 + (P_1 P_3)^2 + \dots + (P_{11} P_{12})^2.(The sum includes all terms of the form (P_i P_j)^2, where 1 \le i < j \le 12.)
Hint(s): Sums of squares of lengths should make you think of what?

Will give brainliest! aubrey was offered a job that paid a salary of $45,000 in its first year. the salary was set to increase by 2% per year every year. if aubrey worked at the job for 20 years, what was the total amount of money earned over the 20 years, to the nearest whole number?

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.

Which of the following is not a subset of {1,2,3}?
