Lucy has two star systems left to visit on her voyage, but her ship is running low on fuel. the first system, ka-77, is 12001200 light years (\text{l. y.})(l. y.) away while the second system, ka-1111, is 1700\text{ l. y.}1700 l. y.. her top priority is to visit star system ka-77. to determine if she'll also be able to visit ka-1111, she must find the distance between ka-77 and ka-1111. if lucy sees an angle of 52^\circ52 ? between ka-77 and ka-1111, how far are ka-77 and ka-1111 apart? do not round during your calculations. round your final answer to the nearest light year

Atype of plant is introduced into an ecosystem and quickly begins to take over. a scientist counts the number of plants after mmonths and develops the equation p(m)= 19.3(1.089)^m to model the situation. most recently, the scientist counted 138 plants.assuming there are no limiting factors to the growth of the plants, about how many months have passed since the plants werefirst introduced? a)o 6.1b)0.6.6c)10 72d)o 23.1
