Find the largest product the positive numbers x, and y, can have if x + y2 = 16.

Answer:

C

Step-by-step explanation:

Answer: Let's use the variables "r" and "c" to represent the cost of one rose and one carnation, respectively.

From the first sentence, we know that 8 roses and 5 carnations cost $31.75. So we can write the equation:

8r + 5c = 31.75

From the second sentence, we know that 1 rose and 3 carnations cost $5.75. So we can write the equation:

r + 3c = 5.75

Now we have two equations with two variables. We can use substitution or elimination to solve for "c". Let's use substitution:

r = 5.75 - 3c (from the second equation)

Substitute this expression for "r" into the first equation:

8(5.75 - 3c) + 5c = 31.75

Simplify and solve for "c":

46 - 24c + 5c = 31.75

-19c = -14.25

c = 0.75

Therefore, the cost for a carnation is $0.75.

Step-by-step explanation:

To solve this expression, we need to apply the order of operations (also known as PEMDAS): 8 15/22 - 3/4 x 2 divided by 12 = 351/44.

What is PEMDAS?

1.  First, we need to simplify any expressions inside parentheses, but there are no parentheses in this expression.

2. Next, we need to perform any multiplication or division, working from left to right. So, we need to calculate 3/4 x 2 = 3/2.

3. Then, we can rewrite the expression with the new result: 8 15/22 - 3/2 divided by 12.

4. Next, we need to perform the division, which means we need to divide 3/2 by 12. To do this, we can rewrite 12 as a fraction with a denominator of 2: 12/1 x 1/2 = 6/1. Then, we can simplify 3/2 divided by 6/1 by multiplying by the reciprocal of 6/1: (3/2) x (1/6) = 1/4.

5. Now we can substitute this value back into the expression: 8 15/22 - 1/4.

6. Finally, we need to convert the mixed number 8 15/22 to an improper fraction: 8 x 22/22 + 15/22 = 181/22.

7. Now we can combine like terms: 181/22 - 1/4 = (181 x 4)/(22 x 4) - 1/4 = 724/88 - 22/88 = 702/88.

8. We can simplify the fraction by dividing both the numerator and denominator by the greatest common factor (GCF), which is 2: 702/88 = 351/44.

Therefore, 8 15/22 - 3/4 x 2 divided by 12 is equal to 351/44.

ƒ and g are inverses of each other.

b. (g(x)) = x; g(f(x))  = x

ƒ and g are inverses of each other

The inverse functions of the functions f(x) and g(x),are determined as follows;

a. f(x) = 2x, g(x) = x/2

f(g(x)) = f(x/2)

f(g(x)) = 2(x/2)

f(g(x)) = x

g(f(x)) = g(2x)

g(f(x))  = (2x)/2

g(f(x))  = x

Since f(g(x)) = g(f(x)) = x, ƒ and g are inverses of each other.

b. f(x) = 2x + 1, g(x) = (x -1)/2

f(g(x)) = f((x-1)/2)

f(g(x)) = 2((x-1)/2) + 1

f(g(x)) = x - 1 + 1

f(g(x)) = x

g(f(x)) = g(2x + 1)

g(f(x)) = ((2x + 1) - 1)/2

g(f(x)) = 2x/2

g(f(x)) = x

Thus, the simplification of the given function using difference quotient formula is found as 4.

The difference quotient is the product of the difference between the function values, f(x + h) - f(x), and indeed the difference between the input values, (x + h) - x, given a function f(x) and two input values, x as well as x + h (where h is indeed the distance between x and x + h).

For the given question:

function F(x) = -4x+8

difference quotient formula:

[f(x + h) -f(x)] / h

Put x = x + h

F(x+ h) = -4(x + h) + 8

F(x+h) = -4x  -4h + 8

F(x) = -4x+8

Now,

[f(x + h) -f(x) ]/ h = [-4(x + h) + 8  + 4x - 8]/ h

On simplifying:

[f(x + h) -f(x) ]/ h = 4h/h = 4

Thus, the simplification of the given function using difference quotient formula is found as 4.

The quotient is 0.9x² + 0.17x - 0.259, and the remainder is 0.181.

Synthetic division is a simplified method of dividing a polynomial by a linear factor of the form (x-a). It is a faster and more efficient method than long division when dividing a polynomial by a linear factor, and is commonly used in algebra and calculus.

To use synthetic division, the coefficients of the polynomial must be written in descending order and any missing terms should be replaced by zero coefficients. The divisor must be a linear factor of the form (x-a), where 'a' is a constant.

Synthetic division can be used to find the quotient and remainder of a polynomial division by a linear factor. It is also used to simplify expressions and solve equations in algebra and calculus.

First, we need to convert the divisor to its opposite sign, so we will be dividing by x - (-0.7) = x + 0.7

The coefficients of the dividend are 0.9, 0.8, 0, 0, so we will set up our synthetic division table as follows:

-0.7 | 0.9 0.8 0 0

      | -0.63 -0.259 0.181

      |____________________

         0.9 0.17 -0.259 0.181

The quotient is 0.9x² + 0.17x - 0.259, and the remainder is 0.181.

Therefore, 0.9x³ + 0.8x = (x + 0.7)(0.9x² + 0.17x - 0.259) + 0.181.

The equation for the volume of the rectangular prism is V = x³ + 2x² - 8x.

A three-dimensional solid structure called a rectangular prism contains six rectangular faces, each of which is perpendicular to the faces around it. The term "rectangular parallelepiped" is another name for it. Rectangular prisms are frequently employed in geometry because they may be used to represent a variety of real-world objects, including boxes, buildings, and rooms. A rectangular prism's surface area is equal to the total of the areas of its six faces, whereas its volume is determined by the product of its length, breadth, and height.

The volume V of a rectangular prism is given by the formula:

V = lwh

Substituting the values:

V = (x + 4)(x - 2)(x)

= (x² + 2x - 8)(x)

Any expression that involves only integers and basic Arithmetic operations can simplify to a rational answer, while expressions involving irrational numbers cannot.

There are several expressions that simplify to a rational answer. In mathematics, a rational number is any number that can be expressed as the ratio of two integers, where the denominator is not zero. Therefore, any expression that involves only integers, addition, subtraction, multiplication, and division can simplify to a rational answer.

For example, if you have an expression like (3 + 2)/(4 - 1), this can be simplified to 5/3, which is a rational number. Similarly, expressions like 6/3 or 7 - 2 also simplify to rational answers.

However, expressions that involve irrational numbers such as pi or the square root of 2 cannot simplify to rational answers. For example, the expression sqrt(2) + 3 cannot be simplified to a rational number.

In summary, any expression that involves only integers and basic arithmetic operations can simplify to a rational answer, while expressions involving irrational numbers cannot.

The combination of goods that would maximize the consumer's Utility per dollar leads to a utility equal to 14 utils.

To determine the combination of goods that would maximize the consumer's utility per dollar, we need to use the concept of marginal utility. Assuming that the consumer has $14 to spend and chips cost $1 while soda costs $2, the consumer could purchase either 14 chips, 7 sodas or a combination of the two.

Let's say the consumer decides to buy x chips and y sodas. The total expenditure would be 1x + 2y, and the total utility would be the sum of the marginal utility of each good multiplied by the quantity purchased.

Assuming the utility function is U(x, y) = x^(1/2) * y^(1/2), the marginal utility of chips would be (1/2)x^(-1/2)*y^(1/2) and the marginal utility of soda would be (1/2)x^(1/2)*y^(-1/2).

The consumer's goal is to maximize the utility per dollar, which is calculated as the total utility divided by the total expenditure. Therefore, the utility per dollar function would be U(x, y)/(1x + 2y).

Using the Lagrange multiplier method, we can find the combination of x and y that maximizes the utility per dollar. The first-order conditions give us the following system of equations:

(1/2)x^(-1/2)*y^(1/2) = λ

(1/2)x^(1/2)*y^(-1/2) = 2λ

x^(1/2)*y^(1/2) = 14

Solving this system of equations, we get x = 4 and y = 49/4. Therefore, the consumer should buy 4 chips and 12.25 sodas, which costs $29.50.

The utility function evaluated at this point is U(4, 49/4) = (4^(1/2))*(49/4)^(1/2) = 14. The utility per dollar function evaluated at this point is U(4, 49/4)/(1(4) + 2(49/4)) = 14/29.50 = 0.4746.

Therefore, the combination of goods that would maximize the consumer's utility per dollar leads to a utility equal to 14 utils.

The probability that a randomly selected student from the set has a height less than 115 cm is approximately 0.04, or 4%

A z-score (or standard score) is a measure of how many standard deviations a data point is from the mean of its distribution. It is a way to standardize data and compare observations from different distributions.

To find the probability that a randomly selected student from the set has a height less than 115 cm, we need to standardize the value using the standard normal distribution.

First, we calculate the z-score:

z = (115 - 150) / 20

  = -1.75

Then, we look up the area under the standard normal distribution curve to the left of z = -1.75 using a table or a calculator. The table or calculator gives us the value 0.0401.

Therefore, the probability that a randomly selected student from the set has a height less than 115 cm is approximately 0.04, or 4%, rounded to two decimal places:
