The area is maximized when half the fence is used parallel to the building, and the other half is split between the ends and partitions.

Each of the 4 kennels is (105/4)' long by (105/5)' wide, that is ...
.. 26.25 ft long by 21 ft wide.

_____
Let x represent the length of fence used parallel to the building. Then the total area is
.. A = x*(210 -x)/5
This is the equation of a parabola with its vertex at x=105, halfway between the zeros at x=0 and x=210.

code is 871

trust me i just did this and got it right

 Opens Right

WORK SHOWN:  

(y−k)²=4*a*(x−h)

Where -

k=3→ y - coordinate of the vertex
h=−2→ x - coordinate of the vertex
a=2→ Distance between the vertex and the focus

Substitute these values in the given formula

(y−3)²=4*2*(x-(-2))

(y−3)²=8(x+2)

THANK YOU HAVE A NICE DAY

Thank you so much!

Great! I'm glad I could help. 

One more thing:

\(0.xy = \frac{xy}{100}\)

\(0.x = \frac{x}{10}\)

And so on. :)

The focus is always 'inside' the parabola curve    vertex 2,3     focus  0,3   is LEFT the vertex so the parabola opens leftward.

Yesssssss !

That's so smart. 

My first insinct was to set up p^3 + 7 + 3p^2 + 6.... etc. 

=^._.^=

Wouldn't this be \(\frac{-37}{100}\)?

hi CPhill

was i right ?

AD = sqrt  [ ( 5 - 0)^2  + (12 - 0)^2 ] =  sqrt [ 25 + 144]   =sqrt (169)   = 13

So  the perimeter =   9  + 12  + 4 + 13   =   38 units 

THANK YOU

i hope u can read this cursive

2. 

40% + 35 % = 80 %    so 20% are dated after 1980

20% is .20 in decimal form

.20 (1600) = 320 coins dated after 1980

j = 7d     given

     let 's' = papers taken from j

j - s   = 40         j= 40 + s

d + s = 40         d = 40 -s       sub these into the original equation

40+s = 7 (40-s)

s = 30 papers

Hello, KOBE!

That answer is not correct!!! The guy who posted that answer made a lot of errors.

CE = 5.5         CF = 11           

CD = 6.05

ED = 2.1

7 cos 210 =  -6.06

7 sin 210 = -3.5i

Well let's say she flies for ONE hour.....then she should be 50.2 miles north and 1 hour's mph east

Bearing 68.9 is actually 21.1 in our usual coordinate 'plane'   (haha)

tan 21.1 = 50.2 / mph        mph = 130 mph

CORERECT!!!!!!!!!!!!!!!!!!!!! 

TYSM! 

One question per post.

You should not be asking anyone to do your homework for you.

You are supposed to post one question and learn from any answer  BEFORE you ask a second question.

And please include a direct link,

or better still, 

write the question or upload a picture of the question directly to the forum.
