Hi there!

v = √2gh
Plug in the given velocity and acceleration due to gravity:
48 = √2(32)h
Square both sides:
2304 = 2(32)h
Simplify:
2304 = 64h
Divide both sides by 64:
h = 36 feet.
Answer:
-7
Step-by-step explanation:
first multiply 3 and 4 because PEMDAS
so it now looks like
12 - 9 - x = 10
now minus 12 and 9
3 - x = 10
move x to the other side by adding x to both sides
3 = 10 + x
and move 10 to the other side by subtracting 10 to both sides
3 - 10 = x
x = -7
now check
3*4 - 9 - (-7) = 10 ?
12 - 9 + 7 = 10 ?
3 + 7 = 10 ?
10 = 10
Answer:
The one highlighted yellow is the correct option
6 liters is to 72 km as 50 liters is to x km
Having obtained:

the next thing to do is collect the first three terms and write them as the square of a binomial, and also collect the last two terms, writing each of them with a denominator equal to 4a^2
We have:

.
Then, we take

to the right side and write these two terms as one:

.
Next, we take the square root of both sides, which has been shown in the solution.
Next, we have to take b/2a to the right hand side as -(b/2a), and removing the square in the denominator of the right hand side expression:

.
