2 answers:
Answer:
180 gallons
Step-by-step explanation:
In order to calculate you just need to calculate the 10% of the herbicide that is being degraded in the first week, so we do a rule of three to calculate that 10%:
So the 10% is 20 gallons, and that is the gallons of herbicide that degraded in the first week, so we just withdraw the 20 gallons degraded from the initial 200 gallons:
200-20=180
So there will still be 180 gallons in the pond after one week.

The capital formation of the investment function over a given period is the
accumulated capital for the period.
- (a) The capital formation from the end of the second year to the end of the fifth year is approximately <u>298.87</u>.
- (b) The number of years before the capital stock exceeds $100,000 is approximately <u>46.15 years</u>.
Reasons:
(a) The given investment function is presented as follows;
(a) The capital formation is given as follows;
From the end of the second year to the end of the fifth year, we have;
The end of the second year can be taken as the beginning of the third year.
Therefore, for the three years; Year 3, year 4, and year 5, we have;
The capital formation from the end of the second year to the end of the fifth year, C ≈ 298.87
(b) When the capital stock exceeds $100,000, we have;
Which gives;
The number of years before the capital stock exceeds $100,000 ≈ <u>46.15 years</u>.
