Answer:
1 1/9
Step-by-step explanation:
put the problem into the calculator and divide. so simple
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
Answer:(2,-1)
Step-by-step explanation: Because you go across the x-axis first and that is your first number(2) and then you look at your y-axis(-1)
Answer:
its Aor the first option because it has repeated x values making it not a function.
Answer:
Step-by-step explanation:
The following information is missing in the question:
We have to find z-score for the given score on this dental anxiety scale: 12, 6
We are given the following information in the question:
Mean, μ = 11
Standard Deviation, σ = 4
We are given that the distribution of score is a bell shaped distribution that is a normal distribution.
Formula:
where x is the given score on this dental anxiety scale.
For x = 12
For x = 6
