Let the width of the field be represented by x.
since the length is two times as long as the width, the length of the field is 2x.
perimeter of field = 6x = 300 feet
x = 50 feet
hence, width,x = 50 feet
length, 2x = 100 feet
Explanation:
The standard form of the equation of a circle is ...
(x -h)² +(y -k)² = r² . . . . . . <em>circle centered at (h, k) with radius r</em>
The general form of the equation of a circle will be ...
Ax² +Bxy +Cy² +Dx +Ey +F = 0 . . . . . A = C for a circle
__
The former is converted to the latter by eliminating parentheses, subtracting r² and collecting terms.
x² +y² -2hx -2ky +(h² +k² -r²) = 0
This shows you that ...
A = C = 1
B = 0
D = -2h
E = -2k
F = h² +k² -r²
__
In general form, we like to have the coefficients be mutually prime integers and the leading coefficient be positive. That is not always possible, depending on the circle being represented.
Answer:
1263 seconds
Step-by-step explanation:
100 meters = 12.63 seconds
multiply both sides by 100 since
100*100= 10,000 meters
12.63*100= 1263 seconds

Answer:
y = 5√2/2
x = 5
Step-by-step explanation:
First find y using the tan method: opposite/adjacent
tan(45) = 5√2/2 ÷ y
y = 5√2/2 ÷ tan(45)
y = 5√2/2
Then find x using the pythagoris theorem: c^2 = a^2 + b^2
x = √ (5√2/2)^2 + (5√2/2)^2
x = 5
