The quadrilateral is a rhombus.<br> If EF = 13 and DF = 18, find EH to the nearest tenth.
-Dominant- [34]

Answer:

EH = 9.4

Step-by-step explanation:

A rhombus is a quadrilateral with equal length of sides.

Given that,  EF = 13 and DF = 18

⇒ DH = HF = \frac{18}{2}

             = 9

The property that the diagonals of a rhombus are at right angle to each other.

Thus, applying the Pythagoras theorem, we have;

/hyp/^{2} = /adj1/^{2} + /adj2/^{2}

(EF)^{2} = (EH)^{2} + (HF)^{2}

(13)^{2} = (EH)^{2} + (9)^{2}

169 =  (EH)^{2} + 81

(EH)^{2} = 169 - 81

           = 88

EH = \sqrt{88}

      = 9.381

The length EH is 9.4

suppose you have 76 feet of fencing to enclose a rectangular dog pen. The function A=38x-x^2, where x= width, gives you the area
yan [13]
If A=38x-x^2 then

dA/dx=38-2x

d2A/dx2=-2

Since the acceleration, d2A/dx2 is a constant negative, when velocity, dA/dx=0, it will be an absolute maximum for A(x)

dA/dx=0 only when 38=2x, x=19

A(19)=38(19)-19^2

A(19)=722-361

A(19)=361 ft^2

So the maximum possible area is 361 ft^2

(This will always be true as the maximum possible area enclosed by a given amount of material will always be a perfect square...)
