The hyperbolic cos (cosh) is given by
cosh (x) = (e^x + e^-x) / 2
The slope of a tangent line to a function at a point is given by the derivative of that function at that point.
d/dx [cosh(x)] = d/dx[(e^x + e^-x) / 2] = (e^x - e^-x) / 2 = sinh(x)
Given that the slope is 2, thus
sinh(x) = 2
x = sinh^-1 (2) = 1.444
Therefore, the curve of y = cosh(x) has a slope of 2 at point x = 1.44
The ratio can be determined as,
Thus, the requried ratio is 7:12.
Why 69 though????????????????????????
Rate is closer to a constant pattern , example: I'm walking at a rate of 2 miles an hour.
Ratio is related to the proportion of two or more objects, example: The ratio for a perfect tang juice is 1 packet of tang dust thingy for 1.5 liters of water.
Hope it helps :)
Answer:
It should be 13 units.
Step-by-step explanation:
In the picture shown, the two red dots are the coordinates (-6, 2) and (6, -3). The smaller light blue dots is the distance from one red dot to the other red dot. I counted 17 units between the two and using a ruler, I estimated 12 units. In conclusion, it should be roughly 13 units. I hope this helps! If this is not the right answer, I would love to recieve some feedback of what I did wrong! Thank you!
