It would take 1 hour 44 minutes to travel the second road and 1 hour 42 minutes to travel the first road
Answer:
a = -
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (105, 27 ) , thus
y = a(x - 105)² + 27
To find a substitute (109, 14 ) into the equation
14 = a(109 - 105)² + 27 ( subtract 27 from both sides )
- 13 = 16a ( divide both sides by 16 )
a = -
The external angle between the secants (20°) is half the difference of the intercepted arcs.
(75° - B)/2 = 20°
75° - B = 40°
75° - 40° = B = 35°
