Question

Based off of the model P= 2t^2 - 4.3t + 462, when will the population reach 716 million?

Answer 1

If the P is representing Population, then you just have to set P=716 and solve for the
when, t is time i guess

Answer 2

what do i do after this? 254=2t^2-4.3t

Answer 3

you have a parabola opening upwards

Answer 4

The math problem requires me to find the year it will reach this population

Answer 5

starting at 1993

Answer 6

yes, you will get two values for time, t, but i assume you can ditch the negative value for time

Answer 7

graph p(t), and see where it intersects p = 716

Answer 8

2005? or 12 years?

Answer 9

716000000=2t^2-4.3t+462
