To solve this problem, we use the tan function. The distance
across the river is the adjacent side, the distance drownstream is the opposite
side while the direction of the boat is the hypotenuse.
tan θ = opposite side / adjacent side
tan 10 = opposite side / 420 ft
opposite side = 74.06 ft
<span>Therefore the boat will move about 74 ft downstream.</span>
Answer:
y = -13
Step-by-step explanation:
y = 5(-2) - 3
y= -10 -3
y = -13
Altitude, like elevation, is the distance above sea level. Areas are often considered "high-altitude" if they reach at least 2,400 meters (8,000 feet) into the atmosphere. ... This is called indicated altitude, and is measured by an instrument called an altimeter. As altitude rises, air pressure drops.
