Answer:

36 in.

Step-by-step explanation:

side = x

x^2 + x^2 = 12.72^2

2x^2 = 161.79

x^2 = 80.899

x = 9

perimeter = 4x = 4 * 9 = 36

Which equations represent the line that is perpendicular to the line 5x − 2y = −6 and passes through the point (5, −4)? Select t
nignag [31]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

On the other hand we have that if two lines are perpendicular, then the product of their slopes is -1. So:

m_ {1} * m_ {2} = - 1

The given line is:

5x-2y = -6\\-2y = -6-5x\\2y = 5x + 6\\y = \frac {5} {2} x + \frac {6} {2}\\y = \frac {5} {2} x + 3

So we have:

m_ {1} = \frac {5} {2}

We find m_ {2}:m_ {2} = \frac {-1} {\frac {5} {2}}\\m = - \frac {2} {5}

So, a line perpendicular to the one given is of the form:

y = - \frac {2} {5} x + b

We substitute the given point to find "b":

-4 = - \frac {2} {5} (5) + b\\-4 = -2 + b\\-4 + 2 = b\\b = -2

Finally we have:

y = - \frac {2} {5} x-2

In point-slope form we have:

y - (- 4) = - \frac {2} {5} (x-5)\\y + 4 = - \frac {2} {5} (x-5)

ANswer:

y = - \frac {2} {5} x-2\\y + 4 = - \frac {2} {5} (x-5)

Width = w
length = w+2

f(w) =w(w+2) = w^2 + 2w.

Please, let me know whether the procedure is clear for you.

The answer is f(w)=w^2 + 2w.

I am simplifying radicals and I've come across one that has me a bit confused.
zhenek [66]

The sqrt of (34 m^4) is  sqrt(34) times sqrt(m^4).

The sqrt of m^4 is easy ... that's just  m^2 .

The other part is more messy.  There's not much you can do with it.

                      sqrt(34) = sqrt(17) times sqrt(2). 

That doesn't help make it any simpler.
You might as well just leave it as sqrt(34). 

Then the final, simplified form of the original expression is

                          m^2 sqrt(34)
