Hello,
Here is the graph of y=|4x+12| which is null for x=-3.
A = pi r^2 78.5 = pi r^2 r = sqrt(78.5/pi) arc length in radians 6 pi cm / (sqrt(78.5/pi) cm/rad) = 3.77 rad or 3.77 rad / (pi rad / 180°) = 120° i assumed that you meant 6 pi cm for arc and the central angle is equal to subtended arc measure.
hope this helps !
Answer:
Point-slope form:
y-5= -1/3 times (x+9)
This is only for the first part
The answer is no solution.
hope that helps!
Really you only go by the denominators. if the two denominators have a same common factor than that's the one you use.
