Answer:
-6y = 70x = 3
Step-by-step explanation:
-6x - 5y= 64x+ y=3
---------------------------
-y - y
---------------------------------
-6x -6y = 64x = 3
------------------------------------
+6x +6x
-------------------------------------
-6y = 70x = 3
Answer:
4.4 t = 13.2
t = 13.2 / 4.4 = 3
t = 3
Step-by-step explanation:
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
1 foot = 12 inches
2 x 12 = 24 +3 = 27 inches
3 x 12 = 36 +5 = 41 inches
27*41 = 1107 square inches
1107 * 0.35 = $387.45
the answer would be revenue
