That you and her have a 50% chance of winning.
It's multiplied by 5, so the amplitude is 5.
The period is pi/2 since it's tan(2t)
168m - it is positive 147 - (-21), so the difference is 168m
Slope is 6/2 which also equals 3 because you have to use the rise over run process.
Answer:
<em>Farmer Bill sold 120 lb of potatoes</em>
Step-by-step explanation:
Suppose farmer Bill had x lb of potatoes. He sold a quarter to the first person. A quarter is written as (1/4)x. After that, Bill had x-(1/4)x = (3/4)x.
Then he sold 4/9 of what was left to the second person, thus it was left 1-4/9=5/9 of the remaining potatoes. Multiplying both factors:

This is the remaining portion of the potatoes.
Finally, he sold 4/5 of it and the last 10 lb. This means 1 - 4/5 = 1/5 of the remaining is equivalent to 10 lb:

Thus:

x = 120 lb
