This can be treated as a work problem and we can solve it as follows:
Harland working alone = 15 minutes
Trudy scatters the leaves + Harland rakes = 20 minutes
We set scattering as a negative value.
1/15 - 1/x = 1/20
x = 60 minutes for Trudy to scatter the leaves alone
Answer:
b
Step-by-step explanation:
50/w=10
50/5=10
w=5
(2/9)³=8/729
That's your answer.
[So big....)
We are given an equation <span> f(n) = 15(1.04)^n where f(n) is the plant height in cm and n is the number of days since the day planted. The domain of the plant is a set including 0 to positive infinity. The y-intercept of the graph is when n = 0 or equal to 15. when n is 1, f(n) is equal to 15.6 . when n is 5, f(n) is equal to 18.25. the rate of change is (18.25-15.6)/(5-1) equal to 0.66</span>
now, that will give you "A", or the compounded amount
what's the interest earned? well, subtract the original amount, the Principal, from A, A - P, and you'd be left with the earned interest
