Coterminal angles are angles that are made by the positive x-axis of the coordinate plane. The positive angle that is less than 2π and is coterminal with 14π/6 is 1/3π.
<h3>What are coterminal angles?</h3>
Coterminal angles are angles that are made by the positive x-axis of the coordinate plane.
The angle that 14π/6 makes from the positive x-axis is 1/3π, which is equal to 60°.
Hence, the positive angle that is less than 2π and is coterminal with 14π/6 is 1/3π.

Answer:
31.6 feet by 15.8 feet.
Step-by-step explanation:
Area of a Rectangle = Length X Breadth = LB
The area of the playground is to be 500 square feet
Therefore:
LB=500
Perimeter of the Rectangle = 2(L+B)
The Chain link fence that costs $2 per linear foot on three sides and a fancier wooden fence that costs $6 per linear foot on the fourth side.
Cost = ${2(L+2B)+6L}=2L+4B+6L=8L+4B
Cost= $(8L+4B)
From: LB=500, B=500/L
Substitute B into 8L+4B
C(L) =
C(L)=
The minimum cost of the fencing occurs when the dimensions are minimum.
If we take the derivative of C(L)
At
Recall: B=500/L
The dimensions that minimizes the total cost of the fencing are 31.6 feet by 15.8 feet.
If both shirts are 25% off, then multiply 20 by .25, which is 5. That's your discount. Subtract that from 20, each shirt (with the discount on both) would be 15 dollars. Fifteen times two is 30, so she would pay 30 bucks for the shirts
