Answer: 
Step-by-step explanation:
Slope of a line passes through (a,b) and (c,d) = 
In graph(below) given line is passing through (-2,-4) and (2,2) .
Slope of the given line passing through (-2,-4) and (2,2) =
Since parallel lines have equal slope . That means slope of the required line would be .
Equation of a line passing through (a,b) and has slope m is given by :_
(y-b)=m(x-a)
Then, Equation of a line passing through(-3, 1) and has slope = is given by

Required equation: 
Answer:
C
Step-by-step explanation:
(3^5)^2 = 3^10
(8^2)^5 = 8^10
therefore
(3/8)^10
I think the answer would be 1.
1.23 is the correct answer
In degrees,
arccos(0.36) = 68.89980398 ≈ 68.9°
In radians,
arccos(0.36) = 1.202528433 ≈ 1.20
