if the actual distance from San Antonio to Houston is approximately 188 miles use the length of the line segments indicated in the figure along with the similar triangles to approximate.
a: The actual distance from Dallas to Houston = _ miles
b: The actual distance from Dallas to San Antonio = _ miles
Answers

Answer:
a) 235 mi
b) 259 mi
Step-by-step explanation:
The scale factor from the map to the real world is apparently ...
(SA-H actual)/(SA-H map) = (188 mi)/(3 in) = 62 2/3 mi/in
Then the actual distance from Dallas to Houston is ...
(3.75 in)(62 2/3 mi/in) = 235 mi
And from Dallas to San Antonio, the distance is ...
(4.125 in)(62 2/3 mi/in) = 258.5 mi ≈ 259 mi

the newspaper reported that on the "big board," where 1.24 billion shares were traded, 1,366 stocks fell and 1,788 rose. On the NASDAQ, where 1.76 billion shares were traded, 1,587 fell and 2,068 rose. Comparing the fractions of stocks that fell to the stocks that rose, which market had the largest fraction?
Answers
Using proportions, it is found that the Big Board market had the largest fraction.
------------------------
Big board:
Total of 1366 + 1788 = 3154 stocks.Of those, 1788 rose.The proportion that rose is:
[tex]p_B = \frac{1788}{3154} = 0.5669[/tex]
------------------------
NASDAQ:
Total of 1587 + 2068 = 3655 stocks.Of those, 2068 rose.The proportion that rose is:
[tex]p_N = \frac{2068}{3655} = 0.5658[/tex]
[tex]p_B > p_N[/tex], thus, the Big Board market had the largest fraction.

After a grueling year of work, you (Padcha) decide you need absolute peace and quiet for about a month (February). You visit San Pedro de Atacama in the Atacama dessert of Chile, one of the most pristine and beautiful spots on earth. Every morning you have an espresso with a Swiss veterinarian, Dieter, that has retired there and maintains a small hotel and cafe. After week 2 of peace and quiet you become restless for a more meaningful existence.
In a conversation Dieter you learn that he also raises Llama's, Alpacas, and Vicuñas (all members of the Camel Family) for their wool. The conversation follow--
Dieter: "Padcha, I have this problem related to the nutrition of my animals. I know the nutritional content of the feeds I have available (see the Daily Nutritional Requirements for Animals table). I also know the cost of a kilogram of each feed (see table). I would love to have a way of selecting a mix of Corn, Tankage, and Alfalfa that minimizes my daily cost of providing good nutrition for my animals."
Padcha: "Dieter, I think I might be able to help. In LP optimization, there is a problem that is called the nutrition problem. Of course, it is not only about nutrition, it's also about allocating available resources, in an optimal way (minimal cost), to satisfy requirements. You can image, that there are a lot of problems like that in business. A typical constraint, say for carbohydrates, would read-- the number of kilos of Corn times 90, plus the number of kilos of Tankage times 20, plus the number of kilos of Alfalfa times 40 must equal a minimum 200 units of carbohydrates. The constraint shows how we use the resources/decision variables (kilos of Corn, etc.) to satisfy nutritional needs.
Daily Nutritional Requirements for Animals
Kg. Corn KG. Tankage Kg. Alfalfa Min. Daily Reqs.
Carbohydrates 90 20 40 200
Protein 30 80 60 180
Vitamins 10 20 60 150
$Cost of feed/Kg. 35 30 25
a) What is the LP for the nutrition problem?
b) Solve the problem using Solver. What is the value of the optimal solution? What is the number of kilos of Corn, Tankage, and Alfalfa? (Place the Answer Report below)
c) What if the requirements were raised by 1 unit for carbohydrates (from 200 to 201). Without re-solving the problem, what is the new optimal solution value and the units of carbohydrates? (Provide the logic for your answer.)
d) What is the allowable range of values for the coefficient of the Tankage in the objective function, for which a change of the optimal decision variables will not occur?

You are essentially asking at this point where is the quadratic function greater than 0. To get the interval find the roots. Between the roots the function is guaranteed to be LESS THAN zero. Everywhere else the function is greater than 0.
[tex]x^2-2x+2=0[/tex]
Use Vieta's rule to get the roots,
[tex](x-1)(x-1)=0[/tex]
Both roots are the same so no value is less than 0 which means all values except at the point of root are strictly greater, the point of root is at [tex]x_{1,2}=1[/tex] which means the set for which the quadratic function is greater than 0 is [tex]\mathbb{R}-\{1\}[/tex] "all real numbers except 1".
To convert this into interval notation use all numbers up to 1 but not including and all numbers after 1 but not including,
[tex](-\infty,1)\cup(1,\infty)[/tex]

Answers
Answer:
r = [tex]\sqrt{\frac{a}{3}}[/tex]
Step-by-step explanation:
1. A = 3r²
(Divide 3 by both sides)
2. A/3 = r²
(Square root both sides)
√A/3 = r
On solving for 'r' we get - r = [tex]\sqrt{\frac{A}{3} }[/tex].
We have the following expression -
[tex]$A=3r^{2}[/tex]
We have to solve for r.
Solve for x : [tex]$x^{2} = 9[/tex]On solving, we get -
x = [tex]$\pm\sqrt{9}[/tex]
x = [tex]$\pm3[/tex]
According to the question, we have -
[tex]$A=3r^{2}[/tex]
[tex]$r^{2} = \frac{A}{3}[/tex]
r = [tex]\pm\sqrt{\frac{A}{3} }[/tex]
Since, the area cannot be negative, therefore -
r = [tex]\sqrt{\frac{A}{3} }[/tex]
Hence, on solving for 'r' we get - r = [tex]\sqrt{\frac{A}{3} }[/tex].

A good doctor recommends that a person who weighs 65 pounds be given 200
milligrams of medicine. If the dosage were proportional to a person's weight, how
many milligrams of medicine would the doctor recommend for a person who
weighs 96 pounds?
Answers
9514 1404 393
Answer:
295 mg
Step-by-step explanation:
The proportion can be written ...
dose/(96 lb) = (200 mg)/(65 lb)
dose = (96/65)(200 mg) ≈ 295.4 mg . . . . . multiply by 96 lb, cancel lb units
The doctor might recommend 295 mg for a 96-pound patient.

express 3x-x^2 as m-(x-n)^2. Ill give brainliest to correct answer!
(Also please see the picture since you might mistake x having a square as a 2x)
Answers
This is simply done by Method of Completing the Square.
3x - x²
Add and subtract half the coefficient of x and square it.
( This is done so there'd be no alterations to the quadractic Expression)
So To start
We'd like x² to be positive...(So factor out a negative).
–(x² - 3x )
Now In this case
You see there's a Negative Outside the the bracket
Instead of adding and Subtracting squared values of half the coefficient of X... We'd Add Twice and do not subtract.
Reason: If you add outside the bracket and subtract the other inside the bracket... This will be wrong because there's a negative patiently waiting outside the bracket to Interact with the negative you subtracted to make it Positive.
See what I mean.
Let's say you added 2² and subtracted 2² in this problem
2² – ( x² - 3x - 2²)
If you decide to open the bracket
You'll have
2² – x² + 3x + 2²
NOW THIS IS WRONG BECAUSE WE ALTERED THIS EXPRESSION. WHERE'D 2² + 2² COME FROM?
THIS IS WHY YOU'LL ADD THE SQUARED COEFFICIENT OF X TWICE IN CASES LIKE THESE.
SO GOING BACK TO THE ORIGINAL QUESTION.
– (x² - 3x )
Adding the half the coefficient of x twice and squaring them...
Coefficient of x = 3
Half of 3 = 3/2
Squaring it gives (3/2)²
NOW PROCEEDING
(3/2)² – [ x² - 3x + (3/2)²]
If you open this bracket... (3/2)² will cancel out with —(3/2)²
Meaning that we haven't altered the expression in any way
Moving On...
Applying basic factorizing principle
9/4 – ( x - 3/2)².
Answer = 9/4 – ( x - 3/2)² Which is in the Form m – ( x - n )²
Therefore m = 9/4 and n = 3/2.
Hope This Helps
