The answer is never, that is, on a 2 dimensional plane. You can perform an experiment to see why it is the case. On curved surfaces though, two lines can intersect one another more than once. For instance, on the surface of planet Earth, two lines can intersect one another, both at the Earth's North Pole and South Pole.
y = Acos(Bx) + D;
D = 4, A = 2. Now T = 2π/B = 5π/8, B = 2π/(5π/8) = 16/5
WE get y = 2cos(16/5x) + 4
Answer:
Domain = {-2, 2, 3, 4, 5}
Range= {6, 0, 6, -1, 3)
It is a function
Step-by-step explanation:
It is a function because there is only one y value for each x value
I think 2,3,4 or B,C,D would be correct.
The area of a triangle is (b•h)/2
And the area of a rectangle and parallelogram would just be b•h
1) 8(6) = 48/2 =24
2) 9(10 2/3) = 96/2 =48
3) 19.2(2.5) = 48
4) 16(3) = 48
Hope this is right and hope it helps. Have a good day
