Which numbers are opposites?

2/3 and 3/2

5/8 and −8/5

3/4 and −3/4

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
