Liono4ka [1.6K]

Answer:

P = mgh

What is the equation in point slope form of a line that passes through the point (–8, 2) and has a slope of 1/2?
Kamila [148]
Point slope equation: 
y-y1=m(x-x1) 
m=slope

So we simply plug in our given information: 
x1=-8 
y1=2
m=1/2

y-2=1/2(x-(-8)  

2 minus signs next to each other make a positive 

Final answer: 
y-2=1/2(x+8)

a ferry traveled 1/6 of the distance between two ports in 3/7 hour. The ferry travels at a constant rate.how much do the ferry t
Dahasolnce [82]

Answer:

1 hour = 7/18 of the distance between two ports

Step-by-step explanation:

Given that:

In 3/7 hours distance traveled is 1/6

For finding distance in one hour, divide both sides by 7/3 so that 3/7 would be cancelled out:

3/7 * 7/3 hours = 1/6 * 7/3 distance

By simplifying:

1 hour = 7/18 of the distance between two ports

This means that in one hour 7/18 of the distance is covered between two ports.

i hope it will help you!
