If it’s volume it’s just L x W x H which is 18 x 10 x 2 which is 360cm^3
Answer:
Because of the range of the sine function.
Step-by-step explanation:
The reason why the value of the sine ratio for an acute angle
of a right triangle must always be a positive value less
than 1 has to do with the the range of the sine function.
The range of the sine function is

But in the first quadrant all y-values are positive and acute angles are less than 90°.
Therefore the range will now be 0≤y<1 for acute angles.
(-4x^2 -6x -1) - (-x^2 -5x +3) = -3x^2 - x - 4
The answer to the question I believe is 3.
