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 = -x - 6
Step-by-step explanation:
y = -x + b
2 = -1(-8) + b
2 = 8 + b
-6 = b
L x W x H
= 5 x 2 x 4
= 10 x 4
= 40
