Answer:
The line is Horizontal Line . y has a value of zero for any value of x.
Volume is Length x Width x height.
The pool is cubical, so the length and width are the same dimension.
First find the volume of the pool that is filled by water:
Volume = 12 x 12 x 2 = 288 cubic meters.
Now convert cubic meters to liters:
1 cubic meter = 1,000 liters
288 x 1000 = 288,000 liters
Answer:
B.50
Step-by-step explanation:
The two angles form a right angle ( indicated by the little square )
Right angles have a measure of 90 degrees
Hence, x + 10 + 30 = 90
( Note that we just created an equation that we can use to solve for x )
We now solve for x using the equation we created
x + 10 + 30 = 90
Combine like terms
x + 40 = 90
Subtract 40 from both sides
x = 50
We have a piecewise function.
Therefore, to find the function, we must evaluate each domain separately.
We have then:
For
