Answer:

Where t represent the time in years
For this case this model follows the general model given by:

Where a = 140 represent the initial amount of bisons and y the number of bisons after t years and b = 2.7 represent the growth rate
For this case we want to find the value of y when t =30, and if we replace the value of t =30 in our function we got:

And if we round to the nearest whole number we got 189 bisons after 30 years
Step-by-step explanation:
For this case we have the following function given:

Okay! For example You want to round 0.843 to the nearest tenth you find the tenth place which is 8 remember this trick 4 or less let it rest 5 or more raise the score so it will be 0.8
Hope this helped!

Answer:
Step-by-step explanation:
19x-9 = 13x+15
by transposing
19x - 13x = 15 + 9
6x = 24
x = 24/6
x = 4
