A rancher wants to build a rectangular pen with an area of 36 m2.

Mathematics

MakcuM [25]3 years ago

a).  If the width is 'w' and the area is 36, then the length is  36/w.
The amount of fencing required is 2 lengths + 2 widths (the perimeter).
That's  <em>2w + 72/w</em>  or  <em>(2/w)(w²+36)</em>  or<em>  2(w + 36/w) </em>.

b).  The shape that requires the minimum amount of fencing is a circle
with area = 36 m² .  The radius of the circle is about 3.385 meters, and
the fence around it is about 21.269 meters.

If the pen must be a rectangle, then the rectangle with the smallest perimeter
that encloses a given area is a square.  For 36 m² of area, the sides of the
square are each <em>6 meters</em>, and the perimeter needs 24 meters of fence to
enclose it.

I don't know how to prove either of these factoids without using calculus.

How do i solve this equation? and could you show it to me step by step?
ipn [44]
The answer is 8 and yea it’s 2 steps first u have to remove the constant so u subtract 74-2=72 and 2-2=0. After u get rid of the constant u divide both sides by 9 basically 72/9 and 9/9 which is 8. So n is equal to 8 I hope this helped. I know it can be confusing

Given f(x) = 3x + 4. Find F-1(7)<br><br> Please help I’ll give you brainiest answer 100points!!!!!
Musya8 [376]

Answer:

f⁻¹(7) = 1

Step-by-step explanation:

Step 1: Write out function

f(x) = 3x + 4

Step 2: Find f⁻¹(x) (or known as inverse f(x))

y = 3x + 4

x = 3y + 4

-3y + x = 4

-3y = 4 - x

y = -4/3 + x/3

Step 3: Plug in 7 into inverse f(x)

f⁻¹(7) = 7/3 - 4/3

f⁻¹(7) = 3/3

f⁻¹(7) = 1
