Lucy has two star systems left to visit on her voyage, but her ship is running low on fuel. The first system, KA-7777, is 1200120012001200 light years (l. y.)(\text{l. y.})(l. y.)left parenthesis, start text, l, point, y, point, end text, right parenthesis away while the second system, KA-11111111, is 1700 l. y.1700\text{ l. y.}1700 l. y.1700, start text, space, l, point, y, point, end text.

Her top priority is to visit star system KA-7777. To determine if she'll also be able to visit KA-11111111, she must find the distance between KA-7777 and KA-11111111.

If Lucy sees an angle of 52∘52^\circ52∘52, degrees between KA-7777 and KA-11111111, how far are KA-7777 and KA-11111111 apart?

b

step-by-step explanation:

the word superfluous means unnecessary

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

answer: the answer is d
