Answer:
y = -1/3x + 5/3
Step-by-step explanation:
First solve the equation. Simply put it is y = -1/3x + 5/9.
So, we have our slope which is -1/3. Now just plug it in.
y - y1 = m(x - x1)
y - 2 = -1/3(x - (-1))
Distribute.
y - 2 = -1/3x - 1/3
Add 2 to both sides
you get y=-1/3x + 5/3
Answer:
y=2x-1

Answer:
65/100 or 13/20
Step-by-step explanation:
65% = 65/100 and simplify to 13/20
Answer:
Step-by-step explanation:
time taken to reach the max height is expressed according to the projectile equation;
tmax = u/g
Given u = 30m/s
g is the acceleration due to gravity = 9.81
t = 30/9.81
t = 3.0secs
hence it will take the flare 3.06secs to reach its maximum height.
Max height = u²/2g
Max height = 30²/2(9.81)
Max height = 900/19.62
Max height = 45.87m
If the people set off an emergency flare from a height of 2 meters above the water, the total height will be 45.87 + 2 = 47.87m
