A 10-ft bar of I-beam weighs 201 lb. What is the weight of a 6-ft length?

If a 10-ft bar weighs 201 lb, then a 1-ft bar should weigh 20.1 lb.

If a 1-ft bar weighs 20.1 lb, then a 6-ft bar should weigh 6 times that.

   6 x 20.1 = 120.6 lb

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
