Answer:

AC = 12 cm

Step-by-step explanation:

AB=9 centimeters, you figure out what times what is 9. in this case, it is 3 for A and B. Then you go to BC=12 and 3 for B and 4 for C making it 12 So AC would equal 3x4.

AC = 21

Assuming this is on a line segment AC would be the full length of the line segment that you are trying to find and point B would be splitting in between.
So if the distance between AB is 9 and the distance between BC is 12 then you just add them up the get the full length of AC which is 21

The question GIVES us an equation:

V₀ = √(v² - 64h) .

It TELLS us that v should be 100 ft/sec and h is 150 ft.
All we have to do is plug the numbers into the equation,
and then do the arithmetic to find V₀.
There's not even any Physics to do. Only arithmetic.

V₀ = √(v² - 64h)

v = 100
h = 150

V₀ = √(100² - 64·150)

V₀ = √(10,000 - 9,600)

V₀ = √400

V₀ = 20 ft per sec .
