Consider the following. x = y + y3, 0 ≤ y ≤ 3 (a) Set up an integral for the area of the surface obtained by rotating the curve about the x-axis and the y-axis. (i) the x-axis S = 3 0 dy (ii) the y-axis S = 3 0 dy (b) Use the numerical integration capability of a calculator to evaluate the surface areas correct to four decimal places. (i) the x-axis (ii) the y-axis

55 because 55 + 55 = 110 good luck babe

1. which statement below is true for hyperbolic geometry?

answer: d

4. satellites sputnik, yeltsin, and plekov often temporarily line up in order in a great circle. the circumference of the earth is 24,900 miles, and the satellites orbit at about 150 miles above the surface. if, while in a great circle, sputnik is 9,000 miles from yeltsin, and yeltsin is 10,500 miles from plekov, how far apart are sputnik and plekov?

answer: b  

6,342 miles

5. identify the statement that is true in spherical geometry.

answer: d  

two distinct lines intersect in two points.
