Answer:
D
Step-by-step explanation:
A sin 2.355/2.355 =0.01745240644 cos -2.355/2.355 root square
=180 so untrue not-1
B. sin =0.01745240644 cos = 0 so untrue not 1.
C sin = 0.01745240644 cos = 180 so untrue not 1
D = - 2.355/2.355= 0.01745240644 cos = 0.01745240644 = -1 so true.
As if we divide 1 into -1 = 1
When we divide 0.01745240644 / 0.01745240644 = will also = 1
The answer is -1 as inverse.
If the US could make 14 stereos/hr or 7 cars/hr, this is a ratio of 2 stereos/1 car, or 1 stereo/0.5 cars. Therefore the US opportunity cost of producing 1 stereo is 0.5 car of half a car.
If China (or Japan? given the question in #2) makes 15 stereos/hr or 5 cars/hr, this is a ratio of 3 stereos/1 car, or 1 stereo/0.33 cars.

Step-by-step explanation: Since the equation of this line is written in
slope-intercept or y = mx + b form, its slope or m is represented by the
coefficient of the x term which in this case is 8/5.
It's y-intercept or b is represented by
the constant term which in this is -5.
To graph the line, start with the y-intercept of -5.
So go down 3 units on the y-axis, plot a point at (0, -3).
From there, take your slope of 8/5, so rise 8 units
and run 5 units the right which should leave you at (5, 3).
Graph the line through those points.
