The perimeter of second plot is 180 feet
<em><u>Solution:</u></em>
Given that,
The second parking lot is being designed so that its perimeter is 3/4 of perimeter of the first parking lot
<h3><u>Find the perimeter of first plot:</u></h3>
Perimeter = 2(length + width)
From given figure in question,
length = 40 feet
width = 80 feet
Therefore,
Perimeter = 2(40 + 80)
Perimeter = 2(120) = 240
Thus, we got,
Perimeter of first parking plot = 240 feet
Also, given that,
Thus perimeter of second plot is 180 feet
Each piece will have an area which is 1/2 of the area of the rectangle. The diagonal cuts the rectangle in half.
= 1/2 ( 2 * 1/1/4)
= 1 1/4 m^2

Hello :)
In 8 years, the father will be 2 times older than the child.
In 8 years, the father will be 40
In 8 years, the child will be 20
40 ÷ 20 = 2
So again, the answer is 8 years :)
Hope this helps and have a great day
Answer:
r = √13
Step-by-step explanation:
Starting with x^2+y^2+6x-2y+3, group like terms, first x terms and then y terms: x^2 + 6x + y^2 -2y = 3. Please note that there has to be an " = " sign in this equation, and that I have taken the liberty of replacing " +3" with " = 3 ."
We need to "complete the square" of x^2 + 6x. I'll just jump in and do it: Take half of the coefficient of the x term and square it; add, and then subtract, this square from x^2 + 6x: x^2 + 6x + 3^2 - 3^2. Then do the same for y^2 - 2y: y^2 - 2y + 1^2 - 1^2.
Now re-write the perfect square x^2 + 6x + 9 by (x + 3)^2. Then we have x^2 + 6x + 9 - 9; also y^2 - 1y + 1 - 1. Making these replacements:
(x + 3)^2 - 9 + (y - 1)^2 -1 = 3. Move the constants -9 and -1 to the other side of the equation: (x + 3)^2 + (y - 1)^2 = 3 + 9 + 1 = 13
Then the original equation now looks like (x + 3)^2 + (y - 1)^2 = 13, and this 13 is the square of the radius, r: r^2 = 13, so that the radius is r = √13.
