Answer:
a ≈ 4.9
Step-by-step explanation:
using the Cosine Rule in Δ ABC
a² = b² + c² - (2bc cosA )
= 16² + 18² - (2 × 16 × 18 × cos15° )
= 256 + 324 - (576cos15° )
= 580 - 576cos15
= 23.6267 ( take square root of both sides )
a =
≈ 4.9 ( to the nearest tenth )
To determine the cost per second can be calculated by converting the given unit in terms of second. The conversion factor that will be used is 1 minute is equal to 60 seconds. Also, use proper dimensional analysis as shown below.
R = ($12,800 / minute) (1 minute / 60 seconds)
R = $213.33/seconds
Therefore, one second of advertisement during prime time costs $213.33.
