The correct answer is option D.
Lin's tour costs 5*14 +50 = 70 +50 = 120. Max's tour costs 120.
Neither tour costs less. Both have the same cost.
Biggest area for smallest perimiter is a circle
she has perimiter aka circumference=2pir
72=2pir
divide both sides by 2
36=pir
divid both sides by pi
11.4592=r
radius=11.4 feet
circle is biggest area
To answer, first, convert the given velocity in km/h to m/s as shown below,
(144 km / hr) x (1000 m / 1 km) x (1 hr / 3600 s) = 40 m/s
The acceleration (a) is solved by through the equation,
a = (Vf - Vi) / Δt
where Vf and Vi are final and initial velocities, respectively and Δt is change in time. Substituting the known values,
a = (0 - 40 m/s) / 12 s = -3.3 m/s²
Thus, the answer to this item is letter B.
