Answer:
Position of the submarine now relative to the water surface 
Step-by-step explanation:
It says that the position of a submarine relative to the water surface was -32 1/4 feet . A downward navigational maneuver increased it's depth by 15 1/2 feet.
Now we need to find about what is the position of the submarine now relative to the water surface.
Downward navigation means we 15 1/2 is negative
so we will just add both values to get the final answer:
Position of the submarine now relative to the water surface = 


Answer:
it's a dirty joke, like when you type things into a calculator and turn it upside down to make it look like a word. It's not an equation
Step-by-step explanation:
Step-by-step explanation:
Hey there!
Here;
Diameter (d) = 13 ft
Radius (r) = 13/2 = 6.5 ft
Now,
Area of a circle= πr²
= (22/7)*(6.5)²
= 132.78 ft²
Therefore, the area is 133 ft².

X^2-4x=0
Let x=0
0^2=4(0)=0
0=0 [checks out]
and
x^2-4x=0
(4)^2-4(4)x=0
16-16=0
0=0 [also checks out]
