Let the side of the square = a units, the area of the square = a^2 sq units
Area of the 4 semicircles = area of 2 circles = 2 pi r^2 = 2pi (1/2 a)^2
= pi a^2 / 2
Probability of a point in the unshaded square being picked) = area square / area of the total figure = a^2 / (a^2 * pi/2) = 1 / pi/2 = 2 /pi
which is approximately 65%
Find the domain by finding where the function is define on the graph. the rang is the set of values that correspond with the domain.
Domain: {x/x<R}
Range:7
Y - y1 = m(x - x1)
slope(m) = 1/2
(6,-3)....x1 = 6 and y1 = -3
now sub...and pay attention to ur signs
y - (-3) = 1/2(x - 6)...not done yet
y + 3 = 1/2(x - 6) <=== ur answer
