Which of the following have a frequency factor of b = 1?
•a sine function whose period is 2pi radians.
•a sine function whose x-coefficient is 2pi
•a cosine function with no phase shift whose x-coefficient is 1.
•a sine function whose graph shows 2 cycles from - 4pi radians to 0.
•a sine function whose graph shows 2 cycles from 0 to 2pi radians.
•a cosine function whose graph shows 4 cycles from 0 to 4pi radians.
•a cosine function whose graph shows 1 cycle from 3pi radians to 5pi radians.

y > 1/3x

y < = -x + 4

hope this : )

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
