From the LORAN navigation system use of hyperbolas, the equationthat a ship can use to navigate its course, in nautical miles, using two stations as foci is x^2/900 - y^2/256=1How far apart are the 2 stations from one another?a. 156 miles, b. 68 miles, c. 578 miles, d. 134 miles, ore. NONE OF THE ABOVE.

Δabc is reflected across line l to form δ alblcl, and a¯¯¯al¯¯¯¯ intersects line l at point d. which equation is not necessarily true?

3-12. write each answer with a reasonable number of figures. find the absolute uncertainty and percent relative uncertainty for each answer. (a) [12.41 (±0.09) + 4.16 (±0.01)] x 7.068 2 (±0.000 4) =? (b) [3.26 (±0.10) x 8.47 (±0.05)] - 0.18 (±0.06) =? (c) 6.843 (±0.008) x 104 + [2.09 (±0.04)- 1.63 (±0.01)] =?

0if x and y vary inversely and y=6 as x=7, what is the constant of variation?
