S =rO
The length of an arc is related to the radius and the central angle in the formula. s = rθ. where s is the arc length, r is the radius and θ is the angle in radians. Remember that to convert from radians to degrees, 2π radians = 360 degrees, so if φ = the angle in degrees, then the equation becomes this:

60.
let x be the number you're trying to solve.
(x/100)25 = 15
x/4 = 15
x = 15(4)
x = 60

X^2 times 4x-x times 4x
kicyunya [14]
If you were to write it fully, as an equation, I believe it would look like this:
    x²(4x-x) *4x
Therefore allowing you to simplify the area within the bracket into:
    x²(3x)*4x
To expand, you simply start on the left and work your way across.
    3x³*4x= 12x⁴

Line CD passes through points C(3, –5) and D(6, 0). What is the equation of line CD in standard form?
Elden [556K]
Slope =   (y₂- y₁) / (x₂- x₁)

Points  C( 3, -5) and D (6, 0)  compare to (x₁, y₁) and  (x₂, y₂)

Slope = (0 - -5) / (6- 3)  =   (0+5) / (3) =  5/3

Slope = 5/3

Equation of line given a slope and point,   y - y₁ = m(x - x₁)

m = 5/3,    let point C( 3, -5) = (x₁, y₁)

  y -  - 5 =  (5/3) (x - 3)
 
  y + 5  = (5/3)(x - 3)

   3(y + 5) = 5(x - 3)
  
    3y + 15 = 5x - 15

     3y =  5x - 15 - 15

     3y = 5x - 30

Hence the equation of the line is 3y = 5x - 30
