Answer:
h = 110.24 m
Step-by-step explanation:
It is given that,
A rock is thrown up from the ground at a velocity of 84 feet per second. The formula 
gives the rock's height in feet after t second.
We need to find the maximum height of the rock. For maximum height put 
So,
Put t = 2.62 s in the equation of height. So,
So, the maximum height of the rock is 110.24 m.
We have a triangle where.
a=adjacent leg of A=30 ft
A=90º-(angle of depression)=90º-10º=80º
b=distance between the base of the lighthouse and the ship
tan A= opposite /adjacent.
tan 80º=b /30 ft ⇒b=(30 ft)(tan 80º)≈170.14 ft
Answer: the distance would be 170.14 ft

Answer: w = -3u/2 + 2
Step-by-step explanation:
-12u + 13 = 8w - 3
-12u + 13 + 3 = 8w -3 + 3
-12u + 16 = 8w
w = -3u/2 + 2
