Given:
To find the arc measure (θ) in radians, we can use the formula:
Now, plug in the given values:
To solve for θ, divide both sides by 4:
Simplify the expression:
So, the arc measure (θ) is 2π/3 radians
So, the minimum cost is $400.
The area of a rectangle is the region occupied by a rectangle within its four sides or boundaries.
And the formula is,
Given that,
Area of the garden=1250 square feet.
Let, the length be and the breadth be
then,
The total cost of the fence is,
Now, differentiating the obtained equation we get,
Therefore the length is 25 ft
And breadth is 50ft
Now, calculating the minimum cost,

Answer:
Dimensions of rectangular garden:
x = 25 feet ( sides along the driveway)
y = 50 feet
Step-by-step explanation:
Rectangular area is:
A(r) = x*y (1)
if we call x one the driveway side the cost of that side will be
6*x
The cost of the other side parallel to driveway side is 2*x and cost of the others two sides are 4*y
Total costs: C = 6*x + 2*x * 4*y (2)
From equation (1)
A(r) = 1250 = x*y ⇒⇒ y = 1250/ x
Plugging that value in equation (2) we get costs as a function of x
that is:
C(x) = 6*x + 2*x + 4* 1250/x
Taking derivatives on both sides of the equation
C´(x) = 6 + 2 - 5000/x²
C´(x) = 8 - 5000 /x²
C´(x) = 0 ⇒ 8 - 5000 /x² = 0
8*x² -5000 = 0
x² = 5000/8
x² = 625
x = 25 feet
and y = 1250/ 25
y = 50 ft
C(min) = 50*2*2 + 6*25 + 2*25
C(min) = 200 + 200
C(min) = 400 $

The greatest common factor of 8x and 40y is 8.
Factors of a number or an algebraic expression are the numbers or expressions which divides the given number evenly.
For example, 10 = 2 × 5
So we can say that 2 and 5 are factors of 10.
Greatest common factor of two or more numbers is the factor which is the greatest among all the common factors of both the numbers.
8x can be prime factorized as,
8x = 2 × 2 × 2 × x
Similarly, 40y can be prime factorized as,
40y = 2 × 2 × 2 × 5 × y
Greatest common factor of both the numbers is the product of the common prime factors of both.
Greatest common factor = 2 × 2 × 2 = 8, which is common to both.
Hence 8 is the greatest common factor of 8x and 40y.
