The production possibilities frontier (PPF) is curved because the cost of production is not constant. If every trade-off were the same, it would create a straight line. But the direction that PPF is curved comes from the way that the trade-offs change
I would convert -2pi / 3 to degrees first by multiplying by 180degrees / pi. It equals 120 degrees.
120 degrees is in quadrant II, which is 90 degrees plus 30 degrees. It is 60 degrees from the 180 degrees.
So the reference triangle you use is 60 degrees.
Cos60 = 0.5
sin60 = sqrt(3) /2
But in quadrant II the only trig ratio that's positive is sin; all others are negative.
So cos120 = -0.5
sin60 = sqrt(3) /2

Answer:
5
Step-by-step explanation:
d = 5
For:
(X1, Y1) = (3, 7)
(X2, Y2) = (8, 7)
Distance Equation Solution:
d=(8−3)2+(7−7)2−−−−−−−−−−−−−−−√d=(8−3)2+(7−7)2
d=(5)2+(0)2−−−−−−−−−√d=(5)2+(0)2
d=25+0−−−−−√d=25+0
d=2–√5d=25
d=5

Answer:
a(2) b(-3) c(3) d (-2)
Step-by-step explanation:
first one remember that when u ÷ two negatives it becomes positive
second one try to invert and then multiply the fractions
third one try to invert and then multiply the fractions
fourth one remember that if you ÷ by one negative the product will be negative
