Step-by-step the table that's flipped the y and x values of the given table

Answer:

Step-by-step explanation:

Given data

speed v= 13 miles per hour

time taken t= 20min to hour 0.3 hours

the distance D

We know that the relationship between speed, time, and distance

speed=distance/time

13=D/0.3

(the expression above describes the relationship between  distance, speed, and time)

making D subject of formula we have

D= 0.3*13

D= 3.9 miles

hence the distance is 3.9miles

Answer:

If your looking for the equation it will be

D = 13 · 1/3

And the answer to this equation is 3.9 miles

Answer: Q= 6x+1

R= -7x+1

Step-by-step explanation:

The quotient is (6x + 1) and the remainder is (-7x + 1).

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given A cubic polynomial 24x³ - 14x² + 20x + 6 divided by 4x² - 3x + 5.

So, (24x³ - 14x² + 20x + 6)/(4x² - 3x + 5).

= (4x² - 3x + 5)(6x + 1) + (-7x + 1)/(4x² - 3x + 5) in rhe form N = DQ + R.

Given:

Nana has a water purifier that filters [tex]\dfrac{1}{3}[/tex] of the contaminants each hour.

Water has contaminants = [tex]\dfrac{1}{2}[/tex]

To find:

The function that gives the remaining amount of contaminants in kilograms, C(t), t hours after Nana started purifying the water.

Solution:

Let C(t) be the remaining amount of contaminants in kilograms after t hours.

Initial amount of contaminants = [tex]\dfrac{1}{2}[/tex]

Decreasing rate is [tex]\dfrac{1}{3}[/tex] .

Using the exponential decay model:

[tex]C(t)=C_0(1-r)^t[/tex]

where, [tex]C_0[/tex] is initial amount of contaminants, r is the decreasing rate and t is time in hours.

Substituting the values, we get

[tex]C(t)=\dfrac{1}{2}(1-\dfrac{1}{3})^t[/tex]

[tex]C(t)=\dfrac{1}{2}(\dfrac{2}{3})^t[/tex]

Therefore, the required function is [tex]C(t)=\dfrac{1}{2}(\dfrac{2}{3})^t[/tex].

10.1 f and g are linearly independent using the Wronskian

10.2 f₁ and g₁ belong to W

10.3 {f₁,g₁} is also linearly independent.

10.1 To show that f and g are linearly independent, we can calculate their Wronskian, which is the determinant of the matrix [f g; f' g'], where f' and g' represent the derivatives of f and g with respect to x. If the Wronskian is non-zero for all x, then f and g are linearly independent. In this case, the Wronskian of f and g is sin(x)cos(x) - cos(x)sin(x) = 0. Since the Wronskian is identically zero, f and g are linearly independent.

10.2 To show that f₁ and g₁ belong to W, we need to demonstrate that they can be expressed as linear combinations of f and g. Using the trigonometric identities, we have f₁(x) = sin(x + a) = sin(x)cos(a) + cos(x)sin(a), and g₁(x) = cos(x + a) = cos(x)cos(a) - sin(x)sin(a). These expressions show that f₁ and g₁ are linear combinations of f and g, with coefficients cos(a) and sin(a).

10.3 To prove that {f₁,g₁} is linearly independent, we can use the Wronskian again. Calculate the Wronskian of f₁ and g₁, which is (cos(x)cos(a) - sin(x)sin(a))(cos(x) - sin(a)) - (sin(x)cos(a) + cos(x)sin(a))(sin(x) - cos(a)). Simplifying this expression, we get cos²(x) - sin²(x) - cos²(a) + sin²(a), which is non-zero for all x. Therefore, the Wronskian is non-zero, indicating that f₁ and g₁ are linearly independent.

The smaller container holds 17 gallons, and the larger container holds 27 gallons.

Let's represent the smaller container's capacity as x gallons. According to the problem, the larger container can hold 7 gallons less than twice the capacity of the smaller container, which can be expressed as 2x - 7.

The total capacity of both containers is given as 44 gallons, so we can set up the equation:

x + (2x - 7) = 44

Simplifying the equation:

3x - 7 = 44

3x = 51

x = 17

Therefore, the smaller container holds 17 gallons.

To find the capacity of the larger container, we substitute the value of x back into the expression 2x - 7:

2(17) - 7 = 34 - 7 = 27

Hence, the larger container holds 27 gallons.

The exercise involves calculations with matrices A, B, and C. We need to determine if matrix products AB, BA, BC, and CB are defined. Additionally, we need to calculate the specific matrix products and determine if BC is equal to CB.

Let's perform the calculations step by step:

(a) To determine if AB is defined, we need to check if the number of columns in matrix A is equal to the number of rows in matrix B. If they are equal, the matrix product AB is defined. If not, the product is not defined.

Matrix A has 2 columns and matrix B has 2 rows, so the product AB is defined.

Calculating AB:

AB = [23 + 83 20 + 88]

[23 + 03 20 + 08]

= [30 64]

[6 0]

To calculate BA, we need to check if the number of columns in matrix B is equal to the number of rows in matrix A. In this case, matrix B has 2 columns and matrix A has 2 rows, so the product BA is also defined.

Calculating BA:

BA = [32 + 02 38 + 02]

[32 + 02 38 + 02]

= [6 24]

[6 24]

(b) To determine if BC is defined, we need to check if the number of columns in matrix B is equal to the number of rows in matrix C. In this case, both matrices have 2 columns and 2 rows, so the product BC is defined.

Calculating BC:

BC = [26 + 85 23 + 81]

[06 + 05 03 + 01]

= [52 22]

[0 0]

To calculate CB, we need to check if the number of columns in matrix C is equal to the number of rows in matrix B. In this case, matrix C has 2 columns and matrix B has 2 rows, so the product CB is also defined.

Calculating CB:

CB = [62 + 30 68 + 30]

[52 + 10 58 + 10]

= [12 48]

[10 40]

Is it true that BC = CB?

BC = [52 22]

[0 0]

CB = [12 48]

[10 40]

BC and CB are not equal. The matrix product is not commutative, so BC and CB may yield different results.

In summary:

(a) AB is defined and the result is:

AB = [30 64]

[6 0]

BA is also defined and the result is:

BA = [6 24]

[6 24]

(b) BC is defined and the result is:

BC = [52 22]

[0 0]

CB is also defined and the result is:

CB = [12 48]

[10 40]

BC and CB are not equal, indicating that matrix multiplication is not commutative.

If the price of rough rice increases from 12,000 to 20,000 rupees per ton, the supply curve of milled rice in India will decrease by 96 million tons per year.

To determine how the supply curve changes when the price of rough rice increases from 12,000 to 20,000 rupees per ton, we need to analyze the given supply function:

Q = 8 + 9p - 12p,

In the supply function, "p" represents the price of milled rice in thousands of rupees per ton. However, there is a typo in the equation provided for the supply function. It appears that the equation contains two terms with the variable "p," which should be corrected.

Assuming the corrected supply function is:

Q = 8 + 9p - 12p',

Where p' represents the price of rough rice in thousands of rupees per ton.

Now, let's calculate the initial supply quantity and then compare it with the new supply quantity after the increase in the price of rough rice.

For the initial price of rough rice (p') at 12,000 rupees per ton:

Q1 = 8 + 9p - 12(12)

Q1 = 8 + 9p - 144

For the new price of rough rice (p') at 20,000 rupees per ton:

Q2 = 8 + 9p - 12(20)

Q2 = 8 + 9p - 240

The change in supply can be calculated as the difference between Q2 and Q1:

Change in supply (ΔQ) = Q2 - Q1

= (8 + 9p - 240) - (8 + 9p - 144)

= -240 + 144

= -96

The change in supply (ΔQ) is -96 millions of tons of rice per year.

Therefore, if the price of rough rice increases from 12,000 to 20,000 rupees per ton, the supply curve of milled rice in India will decrease by 96 million tons per year.
