(a) find the approximations t10 and m10 for 2 25e1/x dx. 1 (round your answers to six decimal places.) t10 = m10 = (b) estimate the errors in the approximations of part (a). (round your answers to six decimal places.) |et| ≤ 0.001667 incorrect: your answer is incorrect. |em| ≤ (c) how large do we have to choose n so that the approximations tn and mn to the integral in part (a) are accurate to within 0.0001? n = for tn n = for mn

answer:

sometimes

*i think

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
