1/u = 1/f -1/v
1/v = 1/u + 1/f
Answer:
375 each descent
Step-by-step explanation:
1500/4 = 375
The point slope form of a line is written as y - y1 = m(x -x1)
Where m is the slope and x1 and y1 are the points on the line.
You are told the slope is 3 and the point is (2,-1/2)
x1 is 2 and y1 is -1/2
Replace those in the equation to get:
y- (-1/2) = 3(x-2)
Simplify to get the final answer:
y + 1/2 = 3(x-2)
its the 3rd answer i think
