Hey there!!

Always remember -

wave length = velocity / frequency

Now substitute the values

Wave length = 10 / 4

Wave Length = 2.5 m

A farmer is building a fence to enclose a rectangular area against an existing wall, shown in the figure below.
Annette [7]

The most appropriate choice for maxima and minima of a function will be given by

Rectangle of length 72 feet and breadth 36 feet has largest area

What is maxima and minima?

Maxima of function f(x) is the maximum value of the function and minima of function f(x) is the minimum value of the function.

Here,

Let the length be x feet and breadth be y feet

The farmer has 144 feet of fencing

Three of the sides will require fencing and the fourth wall already exists.

So,

x + y + y =1 44

x + 2y = 144

Area of rectangle(A) = xy ft^2

                               = (144 - 2y)y

                               = 144y - 2y^2

\frac{dA}{dy} = \frac{d}{dy}(144y - 2y^2)

     = 144 - 2\times 2y^{2-1}\\144 - 4y

For largest area,

\frac{dA}{dy} = 0

144 - 4y = 0 \\4y = 144\\y = \frac{144}{4}\\y = 36

\frac{d^2A}{dy^2} = \frac{d}{dy}(144 - 4y)\\=0-4\\=-4 < 0

Hence area is maximum

For largest area, y = 36 feet

x = 144 - 2\times 36\\x = 144-72\\

x = 72 feet

So length of rectangle is 72 feet, breadth of rectangle is 36 feet

Ed buys a box of eggs costing £2.20, two packs of bacon for £2.80 each and two tins of baked beans.
Vika [28.1K]

Solving a linear equation, we can conclude that each tin costs £0.75

<h3>How much does a tin of beans cost in pounds?</h3>

First, we know that Ed buys one box of eggs for £2.20.

Also two packs of bacon for £2.80 each.

And two tins of beans for X each.

Then the total cost is:

C =  £2.20 + 2*£2.80 + 2*X

Now, we also know that when he pays with £10, he gets a change of £0.70.

Then we can solve the linear equation:

£10 - (£2.20 + 2*£2.80 + 2*X) = £0.70

£2.20 - 2*X = £0.70

£2.20 - £0.70 = 2*X

£1.50 = 2*X

£1.50/2 = X = £0.75

In this way, we can conclude that each tin costs £0.75
