Mrs. Hansen also wants a pretty lawn. The lawn is growing exponentially.
Show that there is an exponential connection:
Time/days | x | 1 | 2 | 4 | 6 | 8 | 10 |
Grass/cm | Y | 4 | 5,3 | 9,6 | 17,1 | 30,6 | 54,76 |
Find b and a, and write the equations.
Explain what y, b, a and x is.
How long will it take for the grass to be 100 cm?
20 days have passed, how long is the grass now?
Enjoy
