Answer:

29.4 %

Step-by-step explanation:

The area of the sector is directly proportional to the angle subtending the arc.

Area of sector/area of circle = 106°/360° = 0.294

The area of the sector is 29.4 % the area of the circle, so

A point chosen at random will be in the shaded region 29.4 % of the time.

If y varies directly as x^2 and y=12 when x=2, find y when x=5

Shkiper50 [21]

$y=ax^2\\\\y=12\ \ \ and\ \ \ x=2\ \ \ \Rightarrow\ \ \ 12=a\cdot 2^2\ \ \ \Rightarrow\ \ \ a= \frac{4}{12}= \frac{1}{3} \\\\y=\frac{1}{3} x^2\\\\x=5\ \ \ \Rightarrow\ \ \ y=\frac{1}{3} \cdot5^2=\frac{25}{3} =8\frac{1}{3}$
