Curvilinear costs always increase: a. when management performs break-even analysis. b. when volume increases, but at a nonconstant rate. c. in constant proportion to changes in production levels. d. on a per unit basis when volume of activity goes down. e. with decreases in volume.

The correct option is : b. When volume increases, but at a nonconstant rate.

Explanation:

Curvilinear costs is a type of expense that does not increase at a constant rate with the production volume. It tends to have a sudden increase at low production volumes, then remains constant in the middle and then increases at high production volumes.

The curvilinear costs does not increase linearly with the production. Therefore, curvilinear cost is also called a nonlinear cost.

Therefore, curvilinear costs always increase at a nonconstant rate with the increase in the production volume.

88 because 4 plus 4 equals 8. 40 plus 40 equals 80. 80 plus 8 equals 88

among other factors, composers started writing dynamic markings in their scores because "new instruments allowed for more dynamic ranges and contrast."

dynamics allude to the loudness or softness of music. dynamics offer an approach to demonstrate articulation in sheet music. they to drive the enthusiastic substance of music through volume and force. maybe you could alter both the volume and the shading profundity on your screen at the same time. we can likewise think about the force side of elements as the quality of a note. a few notes are intended to be played delicately and gently, while others are intended to be played all the more firmly.  

some dynamics markings have a letter 'm,' which remains for mezzo, signifying 'medium.' so a mezzo piano unique stamping resembles this (mp) and intends to play medium calm, while a mezzo specialty dynamic resembles this (mf) and intends to play medium loud.
