A piece of rope that is 26feet long is cut into two pieces. One piece is used to form a circle and the other used to form a square. Write a function g representing the area of the square as a function of the radius of the circle r.
Answers
9514 1404 393
Answer:
g(r) = (13 -πr)²/4
Step-by-step explanation:
The circumference of the circle is given by ...
C = 2πr
The amount of rope remaining after the circle is formed will be ...
26 -2πr
When this is used to form a square, each side of the square will be 1/4 of this length, so is ...
s = (26 -2πr)/4 = (13 -πr)/2
The area of the square is the square of the side lengths, so is ...
g(r) = ((13 -πr)/2)²
g(r) = (13 -πr)²/4 . . . . area of the square as a function of circle radius

Jules owns a square plot of land that measures 30 yards on each side. He plans to divide the land in half by building a fence as shown by the dotted line below. how many yards of fencing does Jules need
A 15yd
B 30 yd
C 30/2yd
D30/2yd
Answers
Answer:
BD = 30√2 yd
Step-by-step explanation:
The shape of the land is a square with 30 yd side length on each side.
The fence to he built is the diagonal of the square BD.
Apply pythagorean theorem to find the number of yards of fencing (BD) he needs.
Thus:
BD² = BC² + CD²
BD² ° 30² + 30²
BD² = 1800
BD = √1800
BD = √(900*2)
BD = 30√2 yd

Answer:
Angle 2=160
Angle 3=10
Step-by-step explanation:
The rhombus is made up of two isoceles triangle.
Angle 1 measures 160.
Since the triangle is a isoceles triangle, the opposite angles of the congruent sides is equal angles to each other.
So the reamaing angles in the top triangle are equal so we can use this equation
Remeber that triangle maximum degree it can hold is 180
[tex]160 + x + x = 180[/tex]
[tex]160 + 2x = 180[/tex]
[tex]2x = 20[/tex]
[tex]x = 10[/tex]
We have two congruent triangle side they share Three sides. SSS
This means the corresponding angle of Angle 1 is Angle 2.
Angle 2=Angle 1 by CPCTC.
Angle 2=160
Angle 3 corresponds with one of the remaining congruent angles so it measures
10.
f(x) = x^2 is stretched vertically by a factor of 4 and shifted 1 unit down.
