Answer:
$1.05
Equation 7*(.05*y) with y being years
Step-by-step explanation:
The start number is 7 and one equation is 7*(.05*y)
With Y being the variable for years
7*(.05*3)
7*.15
1.05 $1.05

Step-by-step explanation:
Answer:
B is the correct one. Second.
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
