Answer:

864

Step-by-step explanation:

216 + 216 = 432 +216= 448 +216= 864  

The minimum length of fencing is 72ft and dimensions are x = 18ft, y=12ft

A fence, wall is a vertical construction used to barricade a space from views, air, or light or to keep out people and animals.

This excludes buildings or parts of buildings that are intended to support a roof, awning, or other horizontal structure, such a building's wall.

let x be the length of each side and y be the width of each side of fence

xy = 216

y = 216/x

total length of fencing = 2x+3y

P = 2x+3y

P = 2x + 3(216/x)

P = 2x + 648/x

On differentiating

P' = 2 - 648/(x²)

for P' = 0

2 = 648/(x²)

(x²) = 324

x = 18

y = 216/18

y = 12ft

Hence length of fencing is = 2x+3y

= 2*18 + 3(216/18)

= 2*18 + 3*12

= 72ft

Answer:

A) interest in the amount of $1,600

Sorry, this is late!

Step-by-step explanation:

Line 2 states that a taxpayer is ineligible to use the form if their total taxable interest is over $1,500. Answer A implies that the interest rate is $1,600 which applies perfectly.

The thing on line 2 that would make the taxpayer ineligible to use this form is D, None of the above.

This refers to the tax form in the United States that is used for people below the age of 65 and have dependents that earn less than $100,000 yearly.

Hence, we can see from line 2, we can see that it is stated that taxable interest is more than $1,500 and the person becomes ineligible and none of the answer choices satisfies this, so option D is the answer.

The Cosine Function

The graph of a cosine function is a sinusoid that starts at its maximum value of 1 at x=0 and takes x=2π radians to complete a full cycle. The function of the parent cosine function is:

[tex]y=\cos x[/tex]

Both the amplitude A and the angular frequency w of a cosine can be modeled by the function

[tex]y=A\cos(\omega x)[/tex]

The graph of the cosine function shown in the figure has an amplitude of A=3 and it completes a full cycle at x=π/2, thus:

[tex]\frac{\pi}{2}\omega =2\pi[/tex]

Thus:

[tex]\omega = 4[/tex]

Therefore, the equation of the sinusoid is:

[tex]y=3\cos (4x)[/tex]

where :

[tex]= \pi sin^2 x* cos ^2x[/tex]

[tex]Volume (V) = \int ^{\pi/2}_{0} \pi \ sin^2 x \ cos^2x \ . dx[/tex]

There are 40 adults and 2 children had haircuts on Friday.

An equation is an expression that shows the relationship between two or more numbers and variables.

We are given the system of equation as;

x + y = 42

4x + 14y = 568

We need to solve, let 'x' = 42-y and substitute this expression for 'x' in the second equation to get:

4(42-y) + 14y = 568

168 - 4y + 14y = 568

168 + 10y = 568

10y = 400

y = 40

therefore, x = 2

There are 40 adults and 2 children had haircuts on Friday.
