Let's see what to do buddy...
_________________________________
STEP (1)
First we need to find the length.
(( length is two times the width ))
Length = 20 × 2 = 40 m
_________________________________
STEP (2)
Pearl will put wire <em><u>around</u></em><em><u> </u></em><em><u>a</u></em><em><u> </u></em><em><u>rect</u></em><em><u>angular</u></em><em><u>.</u></em>
<em>Around</em><em> </em><em>of</em><em> </em><em>rectangular</em> = <em>Perimeter</em><em> </em><em>of</em><em> </em><em>it</em>
So we must to find the perimeter of the rectangular.
So Pearl needs <em>120 meters</em> of wire.

And we're done.
Thanks for watching buddy good luck.

Answer: Linear
It is linear because you can subtract 1 from both sides to get y = 5x-1
That equation is in the form y = mx+b
m = 5 is the slope
b = -1 is the y intercept
<u>Part a)</u> if a page is reduced to 80%, what percent enlargement is needed to return it to its original size?
Let
x---------> the percent enlargement
we know that
the original size is the 100%
so
x*80%=100%
x=(100%/80%)
x=1.25--------> 1.25=(125/100)=125%
therefore
<u>the answer Part a) is</u>
the percent enlargement is 125%
<u>Part b)</u> Estimate the number of times in succession that a page must be copied to make the final copy less than 15% of the size of the original
we know that
A photocopy machine can reduce copies to 80% of their original size
so
Copy N 1
0.80*100%=80%
Copy N 2
0.80*80%=64%
Copy N 3
0.80*64%=51.2%
Copy N 4
0.80*51.2%=40.96%
Copy N 5
0.80*40.96%=32.77%
Copy N 6
0.80*32.77%=26.21%
Copy N 7
0.80*26.21%=20.97%
Copy N 8
0.80*20.97%=16.78%
Copy N 9
0.80*16.78%=13.42%-------------> 13.42% < 15%
therefore
<u>the answer Part b) is</u>
the number of times in succession is 9
The apothem of a square is equal to half its side length. Therefore, the square has a side length of 5. The area of a square equals the s^2. Therefore, the area of the square is 5^2=25. (B)
Answer:
Step-by-step explanation:
1) The given inequality is
Arranging the terms with p² and p, we get
Hence, the inequality is of the form
Ap² + Bp + c < 0
2. A quadratic equation of the form
Ap² + Bp + c < 0 with A > 0 looks like
<u>Check the attached image</u>
The region where the values are negative lies between p₁ and p₂ ...
The p₁ < p < p₂
