Y and x have a proportional relationship, and y=12 when x=8. What is the value of x when y=18?
Bond [772]

Answer:

x = 12

Step-by-step explanation:

Proportional relationship means that \frac{y}{x} = k(a constant)

Here, k = 12/8 = 3/2

So, the equation is \frac{y}{x} = 3/2.

Plug in y = 18, and we get 18/x = 3/2.

18 = 3/2x

x = 12

Differentiating Exponential functions In Exercise,find the derivative of the function. See Example 2 and 3.
Keith_Richards [23]

Answer: The derivative would be f'(x)=2(e^{2x}-e^{-2x})

Step-by-step explanation:

Since we have given that

f(x)=(e^x+e^{-x})^{\frac{4}{2}}\\\\f(x)=(e^x+e^{-x})^2

As we will use "Chain Rule"

and at last we will use the identity ''a^2-b^2=(a-b)(a+b)''

We need to find the derivative of the function:

f'(x)=2(e^x+e^{-x})(e^x-e^{-x})\\\\f'(x)=2(e^{2x}-e^{-2x})

Hence, the derivative would be

f'(x)=2(e^{2x}-e^{-2x})
