A veterinarian has been asked to prepare a diet for a group of dogs to be used in a nutrition study at the School of Animal Scie

nce. It has been stipulated that each serving should be no larger than 10 oz and must contain at least 29 units of Nutrient I and 20 units of Nutrient II. The vet has decided that the diet may be prepared from two brands of dog food: Brand A and Brand B. Each ounce of Brand A contains 3 units of Nutrient I and 4 units of Nutrient II. Each ounce of Brand B contains 5 units of Nutrient I and 2 units of Nutrient II. Brand A costs 5 cents/oz and Brand B costs 6 cents/oz. Determine how many ounces of each brand of dog food should be used per serving to meet the given requirements at a minimum cost.

Answer:

Costs are reduced when you have 3 ounces of brand A and 4 ounces of brand B for a cost of 39 cents / serving.

Explanation:

Yes:

x = ounces of brand A

y = ounces of brand B

The objective function and restrictions will be as follows:

Minimize cost function, C = 5x + 6y

This function is subject to:

x + y <= 10

3x + 5y> = 29 eq. 1

4x + 2y> = 20 eq1.2

x, y> = 0

We need to graph the constraints. First, x, y> = 0 their axes meet at x and y as limits. x + y <= 10 is a line from (0.10) to (10.0) and is equal to the area below the graph. The equation 3x + 5y> = 29 passes through (0.5.8), (29 / 3.0) and is equal to the area on the line. 4x + 2y> = 20 passes from (0,10), (0,5) and is equal to the area on the line.

The limits are delimited by (0.10), (10.0), (29 / 3.0). Solving the equations:

12x + 20y = 116 (multiplying eq. 1 by 4)

-12x - 6y = -60 (multiplying eq. 2 by -3)

14 y = 56

y = 4

4x + 8 = 20

x = 3

Replacing in the objective equation:

C = 5 (0) + 6 (10) = 60

C = 5 (29/3) + 6 (0) = 48.33

C = 5 (10) + 6 (0) = 50

C = 5 (3) + 6 (4) = 39

Costs are reduced when you have 3 ounces of brand A and 4 ounces of brand B for a cost of 39 cents / serving.

Why is the study of population composition very useful ? Give reason<br>​
grigory [225]

The study of population is useful because you can see how popular sections of your country or even the world are. You can see where the most dense parts of Cities and countries are to see what kinds of regulations you might have to put in place for say, worldwide pandemics such as the Coco-19 pandemic. It's also useful because you can see why certain area are more popular than others. reaons might include things like mining towns drawing in people from around that area etc etc. The study of population might also be useful if you're trying to establish a busniess and want to start it in a place you know it'ss be successful, such as a higher populated town near you.

The study of population can also be refered t as population demographics or demography.

When exercising, which hormone level decreases in females often causing a better mood?
skad [1K]

Answer

Cortisol

Explanation:

Cortisol or stress hormone is a steroid  hormone  produced in the adrenal gland( Cortex) .A spike in the levels of this hormone suppresses Serotonin levels in the blood. Serotonin  is a neuro- transmitter in the brain  for mood regulation and balance of memory., good sleep sexual  function.

A spike in the levels in the cortisol level in the blood brings a corresponding decrease in the  levels of Serotonin,which therefore leads to mood swings depression and insomnia,anxiety  by reducing the receptors for serotonin,and therefore disrupting Endorphins levels in the brain.

Exercises decreases the levels of cortisol in the blood,and  boost the levels of serotonin therefore boosting the amount of serotonin in the blood  ,thus promoting good mood, reduce  depression etc
