Hallar la ecuación de la circunferencia que pasa por los puntos (0,0) (3,4) (6,2)

Answer:

a) C(n) = 0.74 * min(n, 100) + 0.69 * max(n - 100, 0)
b) 39.22
c)  143.69

Step-by-step explanation:

(a) We can write a piecewise function to describe the cost C(n) of n CDs purchased:

C(n) = 0.74 * min(n, 100) + 0.69 * max(n - 100, 0)

(b) The cost of 53 CDs is:

C(53) = 0.74 * min(53, 100) + 0.69 * max(53 - 100, 0) = 0.74 * 53 = 39.22

(c) The cost for 201 CDs is:

C(201) = 0.74 * min(201, 100) + 0.69 * max(201 - 100, 0) = 0.74 * 100 + 0.69 * 101 = 74 + 69.69 = 143.69

The solution of the inequality 3x < 13 is x < 4.33.

None of the given option is correct.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Answer:

The range of acceptable length is between 35.28 inches and 36.72 inches.

To calculate the range of acceptable length:

Lower bound: 36 in. - (36 in. x 0.05) = 35.28 in.

Upper bound: 36 in. + (36 in. x 0.05) = 36.72 in.

The system of equations are solved and the number of performers for the show A is 10,034

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as T

Now , the value of T is

The total number of performers in the two shows T = 16,756

A + B = 16,756

The number of performers in show A = 3312 + number of performers in show B

Substituting the values in the equation , we get

A = B + 3,312

On simplifying the equation , we get

A + A - 3,312 = 16,756

Subtracting 3,312 on both sides of the equation , we get

2A = 16,756 + 3,312

2A = 20,068

A = 10,034

Hence , the equation is A = 10,034

Answer: a) To make apple crumble for 16 people, Farid will need to double the ingredients as compared to serving 8 people. Hence, he will need:

700g * 2 = 1400g of apples

240g * 2 = 480g of sugar

180g * 2 = 360g of flour

So, Farid needs 360g of flour to make apple crumble for 16 people.

b) To make apple crumble for 2 people, Amal will need to use 1/8 of the ingredients as compared to serving 8 people. Hence, she will need:

700g / 8 = 87.5g of apples

240g / 8 = 30g of sugar

So, Amal needs 30g of sugar to make apple crumble for 2 people.

c) To make apple crumble for 6 people, Shahina will need to adjust the ingredients based on the apples she has available. To calculate the amount of sugar and flour required, she can use the ratio of sugar and flour to apples as follows:

Sugar: 700g / 8 = 87.5g per serving * 6 people = 525g

Flour: 700g / 8 = 87.5g per serving * 6 people = 525g

Since Shahina has plenty of the other ingredients, including butter, she can make apple crumble for 6 people with the amount of apples she has available. So, the answer is Yes, Shahina can make apple crumble for 6 people.

The Canal's price/earnings ratio is 2.92.

To calculate Canal's price/earnings ratio, we need to find the earnings per share (EPS) first. The EPS can be calculated by dividing the net income by the weighted average number of common shares outstanding.

The weighted average number of common shares outstanding can be calculated as follows:

Weighted average number of common shares outstanding = Total number of common shares - Weighted average number of treasury shares

Weighted average number of common shares outstanding = 24,200 - 4,200 = 20,000

EPS = Net income / Weighted average number of common shares outstanding

EPS = $260,000 / 20,000 = $13

Finally, the price/earnings ratio can be calculated by dividing the market price per share by the EPS:

Price/earnings ratio = Market price per share / EPS

Price/earnings ratio = $38 / $13 = 2.92

The linear function for the population in t years after 2000 is given as follows:

P(t) = 2200t + 44000.

The estimate for the population in 2010 is given as follows:

66,000.

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

Two points for the function are given as follows:

(5, 55000) and (8, 61600).

Dividing the change in the output by the change in the input, the slope m is given as follows:

m = (61600 - 55000)/(8 - 5)

m = 2200.

Hence:

P(t) = 2200t + b.

When x = 5, y = 55000, hence the intercept b is given as follows:

55000 = 2200(5) + b

b = 55000 - 2200(5)

b = 44000.

Hence the function is:

P(t) = 2200t + 44000.

2010 is 10 years after 2000, hence the estimate is given as follows:

P(10) = 2200(10) + 40000

P(10) = 66,000.

The equation which models the product is, A = 6 x 8

The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the components that are multiplied are referred to as the factors.

Given that,

A area model,

which has 6  box in column arrangement and 8  box in row arrangement,

Suppose, each box has 1 unit square area

Now, area of a model can be written as,

Area = Number of box in column x Number of box in row

Number of box in column  = 6

Number of box in row = 8

Each box has 1 unit square area,

So,

The solution for the One-Variable Addition Equations is,

1: d = 0.6,  2:  k = 11,  and 3: y = 3.

When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."

There are both one-variable and two-variable linear equations.

Given 1: d  + 3.2 = 6.3 - 2.5

subtract 3.2 from both sides

d = 6.3 - 2.5 - 3.2

d = 0.6

2: 25 + k + 4(1/4) = 37

divide 4/4 = 1

25 + k + 1 = 37

k = 37 - 26

k = 11

3: 4(1/2) + y = 10(1/2)

so 4/2 = 2 and 10/2 = 5

2 + y = 5

y = 3

[tex]\dfrac{2}{v-2}=-6\:+\:\dfrac {1}{v-1}\\\\[/tex]

Find the LCM of the denominators:

LCM = [tex]\left(v-2\right)\left(v-1\right)[/tex]

Multiply by LCM:

[tex]\dfrac{1}{v-1}\left(v-2\right)\left(v-1\right):\quad v-2[/tex]

In mathematics, differentiation is the process of determining the derivative, or rate of change, of a function. Differentiation is a technique for determining a function's derivative. Differentiation is a mathematical procedure that determines the instantaneous rate of change of a function based on one of its variables. The process of finding the derivative of dependent variable in an implicit function by differentiating each term separately

Given data ,

Let the function be represented as f ( x )
