The equation to determine the total cost for playing handball is
f ( x ) = 15x + 150
where x is the number of times Roman plays
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of times Roman plays be = x
Now , the initial amount Roman paid to join the club = $ 150
The additional amount Roman pays for each play = $ 15
So , the equation will be
The total additional amount Roman pays if he plays x number of times is =
number of times Roman plays x additional amount Roman pays for each play
Total additional amount Roman pays if he plays x number of times is = 15x
So , the total cost of playing handball be f ( x ) , where x is the number of times Roman plays
Now , the equation will be
The total cost of playing handball f ( x ) = initial amount Roman paid + Total additional amount Roman pays
The total cost of playing handball f ( x ) = 150 + 15x
Therefore , the equation is f ( x ) = 15x + 150
Hence , The equation to determine the total cost for playing handball is
f ( x ) = 15x + 150
where x is the number of times Roman plays

Answer:
Length of the arc = 5.25017 feet
Step-by-step explanation:
The line from the middle of the tree to the tip of the tangent lines is 33 ft and from the circumference of the tree its 27ft. One of the right angle triangles is picked and the angle is determined using SOHCAHTOA
Hence Tan X = 6/27
X = Tan-1 (6/27) = 12.52880770915o
Hence both sum of angles where tangent lines meet = 2 x 12.52880770915o = 25.05761541830o
Angle of the arc inside the circle = 50.115o
Length of the arc = 50.115/360 x (2x22/7 x 6) = 5.25017040025ft
