Brain weight B as a function of body weight W in fish has been modeled by the power function B = , where B and W are measured in grams. A model for body weight as a function of body length L (measured in centimeters) is W = 0.12L^2.53. If, over 10 million years, the average length of a certain species of fish evolved from 13 cm to 22 cm at a constant rate, how fast was this species' brain growing when the average length was 19 cm? (Round your answer to four significant figures.)

1/2*qr*rs

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
