Answer: 64,000 square inches or 450 square feet

Step-by-step explanation:

The answer needs to be in square feet so divide 36 inches by 12 because there are 12 inches in a foot.   You should get 3. Then multiply 3 by 150 because The paper is a rectangle and you find rectangle area by doing length times width.  Your answer should be 450 square feet.

Find the derivative of f(x)= e^(4x) + e^-(4x)
ololo11 [35]

Answer:

f'(x)=4e^{4x} -4e^{-4x}

Step-by-step explanation:

To find this derivative, we will need to use the chain rule.

As there is a variable in the exponent we can use this formula:

f'(x)=u'e^u

In this case, u=4x and u=-4x

This means that u'=4 and u'=-4 respectively

This gives us f'(x)=4e^{4x} -4e^{-4x}

You are designing a rectangular garden. the garden will be enclosed by fencing on three sides and by a house on the fourth side.
RUDIKE [14]
Suppose the dimensions of the rectangle is x by y and let the side enclosed by a house be one of the sides measuring x, then the sides that is to be enclosed are two sides measuring y and one side measuring x.

Thus, the length of fencing needed is given by

P = x + 2y

The area of the rectangle is given by xy,

i.e.

xy = 288  \\  \\  \\  \\ \Rightarrow y= \frac{288}{x}

Substituting for y into the equation for the length of fencing needed, we have

P=x+2\left( \frac{288}{x} \right)=x+ \frac{576}{x}

For the amount of fencing to be minimum, then

\frac{dP}{dx} =0 \\  \\ \Rightarrow1- \frac{576}{x^2} =0 \\  \\ \Rightarrow \frac{576}{x^2} =1 \\  \\ \Rightarrow x^2=576 \\  \\ \Rightarrow x=\sqrt{576}=24

Now, recall that

y= \frac{288}{x} = \frac{288}{24} =12

Thus, the length of fencing needed is given by

P = x + 2y = 24 + 2(12) = 24 + 24 = 48.

Therefore, 48 feets of fencing is needed to enclose the garden.
