Gemiola [76]

Answer:

When you see a formula like this, try to operate, so you will see some identities sooner or later. In this case, we have a substraction identity:

\frac{cos ( \alpha  -  \beta )}{cos  \alpha cos  \beta }  =  \frac{cos   \alpha cos  \beta + sin \alpha sin  \beta }{cos  \alpha cos  \beta }  = 1 + tan α · tan β

A boat is traveling at 43.2 m/s. It then goes down a faster part of the river and is now going 144
Marina86 [1]

Answer:

Step-by-step explanation:

boat was at 43.2 m/s   speed increase to 144 m/s

if the boat was moving 0 m/s and increased to 144 m/s - 43.2 m/s accelerating at 25.2 m/s²,  it would take the same amount of time

25.2 m/s² × x seconds = (144 - 43.2) m/s      solve for x in seconds

x seconds = 100.8 m/s   /  25.2 m/s²

x seconds = 4 (m/s /ms²)  = 4 (m/s × s²/m)  = 4 seconds   the  units match

x = 4 seconds
