A shelter has enough food to feed an average of 80 hungry people a day for 14 days. If an average of 32 people are at the shelte
Katen [24]

Answer:

  • <u>35 days. </u>

Explanation

The capacity of the shelter is a constant. It is 80 people × 14 days.

That is an inverse relation: the product of the number of people and the number of days will be always the same.

As the number of people decreases the number of days that the food lasts increases, in a proportion such that the product of the days and the number of people is the same.

Thus, for 32 people the number of days the food lasts is x, such that:

  • 32 people × x = 80 people × 14 days

Solving for x:

  • x = 80 people × 14 days / 32 people
  • x = 35 days ← answer

The food will last 35 days.

How many years will it take for an initial investment of $20000 to grow to $50000? Assume a rate of interest of 17% compounded c
Gemiola [76]

Answer:

Years = natural log (total / principal) / rate

Years = natural log (50,000 / 20,000) / .17

Years = natural log (2.5) / .17

Years = (0.9162907319) / .17

Years = 5.3899454818 =

Years = 5.4 (rounded)

SUppose the total cost C(x) to manufacture a quantity x of insecticide (in hundreds of liters) is given by
Hitman42 [59]

Answer:

a) C(x) is increasing in two regions: (i) (+\infty, 8\,s) and (ii) (10\,s,+\infty).

b) C(x) decreases in (8\,s, 10\,s).

Step-by-step explanation:

Let C(x) = x^{3}-27\cdot x^{2}+240\cdot x +850, where x is the quantity of insecticide, measured in hundreds of liters, and C(x) is the total manufacturing cost as a function of the quantity of the insecticide, measured in US dollars. A possible approach to determine which regions of C(x) are decreasing and increasing by means of the first derivative and graphing tools. The first derivative of the function is:

C'(x) = 3\cdot x^{2}-54\cdot x+240 (1)

Please notice that regions where C(x) is increasing has C'(x) > 0, whereas C'(x) < 0 when C(x) < 0.

We notice that C(x) is increasing in two regions: (i) (+\infty, 8\,s) and (ii) (10\,s,+\infty). Besides, C(x) decreases in (8\,s, 10\,s).
