Answer:
i think u are saying this
The formulas for finding arc length utilize the circle's radius. Since the radius is half the diameter of a circle, to find the radius, simply divide the diameter by 2.
the length is 210
Answer:
y = 234t
Step-by-step explanation:
Divide the equation by t on both sides. See image.
Domain is the numbers you can use
you can't use any numbers that make an impossibility like a negative square root or dividing by 0
set the denomenator equal to 0 to find what values of x make it 0
x^3-1=0
add 1 both sides
x^3=1
cube root both sides
x=1
domain is all real numbers except for 1
range is the numbers you get from inputing domaain
there is a vertical assemtote there so all bases are covered
range is how high and low y goes
domain is how far left and right x goes
domain is all real numbers except x=1
range is all real numbers
