Answer:
119.38
Step-by-step explanation:
the circumference is πd so it is 19 X 2, which is 38, times π, which is 38π. this equals 119.38
G(5) = -2(5) + 5 = -5
(f o g)(5) = f(-5) = -20 + 3 = -17 (answer)
Answer:
∠ ADC = 53°
Step-by-step explanation:
Note the angle between the radius and the tangent is 90°
The sum of the angles in quadrilateral AOCB = 360°, thus
∠ AOC = 360° - (90 + 90 + 74 )° = 360° - 254° = 106°
∠ AOC is twice the angle on the circumference ∠ ADC, thus
∠ ADC = 106° ÷ 2 = 53°
The slope is - 4 / 3
Therefore the equation is
y = - 4x / 3
