Question 444864: Some types of worms have a remarkable ability to live without moisture. The following table from one study shows the number of worms surviving after x days without moisture.
x is days and w is worms.
x = 0, 20, 40, 80, 120, 160
w = 50, 48, 45, 36, 20, 3
A) Use the equation W = -0.0014x^2 - 0.076x + 50 to find W for each x-value in the table. (Your can show me one and I may be able to get the rest)
B) Discuss how well this equation approximates the data.
C) Use the equation to estimate the number of worms on day 60 and 180. Which answer is most accurate and explain?
