Answer:

Sadie's family car is more fuel efficient.

Step-by-step explanation:

Given;

Sadie's family car rating, S = 42 miles per gallon

Nanette's family car rating, N = 6 liters per 100 km

Sadie's family car rating, in liters per 100 km

[tex]= \frac{42 \ miles}{gallon} *\frac{1.609 \ km}{1 \ mile}*\frac{1 \ gallon}{3.79 \ liters} \\\\ = (\frac{42*1.609}{3.79} )\frac{km}{liter}\\\\ = (\frac{3.79}{42*1.609} )\frac{liter}{km}\\\\=(\frac{3.79}{42*1.609} )(\frac{100}{100}) \frac{liter}{km}\\\\= (\frac{3.79*100}{42*1.609} )(\frac{1}{100}) \frac{liter}{km}\\\\= (\frac{3.79*100}{42*1.609} ) \frac{liter}{100\ km}\\\\= 5.61 (\frac{liter}{100\ km})\\\\= \frac{5.61 \ liters}{100 \ km}[/tex]

Also, Nanette's family car rating, in liters per 100 km = 6 liters / 100km.

Thus, Sadie's family car uses lesser fuel, because of this Sadie's family car is more fuel efficient.

7x - 4 = -4

add 4 to both sides

7x = 0

x = 0

Answer:

x = 0

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 4 to both sides of the equation:

7x - 4 (+4) = -4 (+4)

7x = -4 + 4

7x = 0

Next, divide 7 from both sides of the equation:

(7x)/7 = (0)/7

x = 0/7

x = 0

0 is your answer.

Answer:

Step-by-step explanation:

Use the midpoint formula: [tex]\frac{ChangeInX}{2} ,\frac{ChangeInY}{2}[/tex]

So, the Change In X is 2-8 = -6

And the Change in Y is 7-4 = 3

Once you divide both of the changes by 2, you get

X: -3

The graph of the function is a parabola opening upwards. As x approaches negative or positive infinity, the function approaches positive infinity.

The given function is f(x) = 2x^2 + 10x + 12. Let's analyze the graph of the function and test its limits.

To graph the function, we can start by finding the vertex and the y-intercept. The vertex of a quadratic function in the form f(x) = ax^2 + bx + c can be found using the formula x = -b/2a. In this case, a = 2 and b = 10.

x = -10 / (2 * 2) = -10 / 4 = -2.5

Substituting the x-coordinate of the vertex back into the function, we can find the y-coordinate:

f(-2.5) = 2(-2.5)^2 + 10(-2.5) + 12

        = 2(6.25) - 25 + 12

        = 12.5 - 25 + 12

        = -0.5

So, the vertex of the parabolic graph is (-2.5, -0.5).

Next, let's find the y-intercept by setting x = 0:

f(0) = 2(0)^2 + 10(0) + 12

     = 12

So, the y-intercept is (0, 12).

Now, we can plot these points and sketch the graph of the function. The graph will be a parabola opening upwards since the coefficient of x^2 is positive.

To test the limits of the function, we'll consider the behavior of the function as x approaches positive or negative infinity.

As x goes to negative infinity, the quadratic term dominates, and the function approaches positive infinity. So, the limit as x approaches negative infinity is positive infinity.

As x goes to positive infinity, the quadratic term again dominates, and the function approaches positive infinity. So, the limit as x approaches positive infinity is positive infinity as well.

In summary, the graph of the function is a parabola opening upwards. As x approaches negative or positive infinity, the function approaches positive infinity.

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.

The minimum number of carrots to cut up for which it will be faster to use a food processor than the knife and cutting board is 11.

In order to find the minimum number of carrots to cut up for which it will be faster to use a food processor than the knife and cutting board, we need to calculate the time taken by each method and then compare it. Let's say the minimum number of carrots is x.

Here's how we can calculate the time taken to chop x carrots:

Time taken using knife and cutting board = 45x + 25 (25 is added for the time taken to clean the knife and board)

Time taken using food processor = 12x + 360 (360 is added for the time taken to clean the food processor)

Now, we need to find the value of x for which the time taken using the food processor is less than the time taken using the knife and cutting board.

So,12x + 360 < 45x + 2512x - 45x < 25 - 360-33x < -335x > 10.15

Therefore, the minimum number of carrots to cut up for which it will be faster to use a food processor than the knife and cutting board is 11.

Thus, the minimum number of carrots to cut up for which it will be faster to use a food processor than the knife and cutting board is 11.

To calculate a three-month moving average for monthly forecasting, you need to follow these steps: Gather the historical data, Determine the time period, Calculate the moving average, Repeat the process.

Gather the historical data: Collect the monthly data for the specific variable you want to forecast. For example, if you want to forecast sales, gather the sales data for the past several months.

Determine the time period: Decide on the time period for your moving average. In this case, it is three months.

Calculate the moving average: Add up the values for the variable you are analyzing over the past three months and divide the sum by three to get the average. This will be your moving average value for the third month.

Repeat the process: Shift the time period by one month and calculate the moving average for the new three-month period. Continue this process for each subsequent month, updating the time period and calculating the moving average accordingly.

For example, let's say you have the following sales data for the past six months:

Month 1: 100 units

Month 2: 120 units

Month 3: 110 units

Month 4: 130 units

Month 5: 140 units

Month 6: 150 units

To calculate the three-month moving average for Month 4, you would add up the sales values for Month 2, Month 3, and Month 4 (120 + 110 + 130 = 360) and divide it by three to get an average of 120 units. Repeat this process for each subsequent month to obtain the moving average values for your forecast.

Note that the number of data points you include in the moving average calculation and the frequency of the data (monthly in this case) can be adjusted based on your specific needs and the nature of the data.

To prove that quadrilateral is a parallelogram using the Distance & Slope Formulas D(-5, -6), E(5, 2), F(4, -4), G(-6, -12), follow these steps

:Step 1: Plot the points in a coordinate plane: (D) (-5,-6), (E) (5,2), (F) (4,-4), (G) (-6,-12)

Step 2: Find the distance of all sides using distance formula.

Distance Formula =sqrt((x2 - x1)² + (y2 - y1)²)DE

                              = sqrt((5 - (-5))² + (2 - (-6))²)

                              =sqrt(10²+8²)

                              =sqrt(164)

                              = 2 sqrt(41)EF

                              = sqrt((4 - 5)² + (-4 - 2)²)

                              =sqrt((-1)²+(-6)²)

                              =sqrt(37)FG

                              = sqrt((-6 - 4)² + (-12 - (-4))²)

                              =sqrt((-10)²+(-8)²)

                              = 2sqrt(41)DG

                              = sqrt((-6 - (-5))² + (-12 - (-6))²)

                              =sqrt((-1)²+(-6)²)

                              =sqrt(37)

Since the opposite sides are equal, we can say that DE = FG and DG = EF.

Step 3: Find the slope of all sides using slope formula.

Slope Formula = (y2-y1)/(x2-x1)DE

                         = (2-(-6))/(5-(-5))

                         =8/10=4/5FG

                         = (-12-(-4))/(-6-4)=-8/-10=4/5DG = (-6-(-12))/(-5-(-6))=6/1=6EF = (-4-2)/(4-5)=-6/-1=6

Since opposite sides have the same slope, DE // FG and DG // EF. Therefore, we can conclude that the quadrilateral is a parallelogram.In conclusion, the quadrilateral is a parallelogram because opposite sides are parallel.

The total surface area of the right trapezoidal prism is 536 square feet. Therefore, the approximate surface area of sphere is 1,256.6 square inches. The surface area of  right trapezoidal prism is 1,485 square feet.

Surface area of the sphere:

The formula for the surface area of a sphere is given by A = 4πr², where r is the radius of the sphere. Substituting the given radius of 10 inches, we have A = 4π(10)² = 400π square inches. The exact value is 400π square inches. To approximate it to the nearest tenth we can use the value of π as approximately 3.14159. Therefore, the approximate surface area is 400π ≈ 400(3.14159) = 1,256.6 square inches.

Surface area of the right trapezoidal prism:

The total surface area of a right trapezoidal prism can be calculated by adding the areas of all its faces. The formula is A = 2h(b₁ + b₂) + (b₁ + b₂)(x + y), where h is the height of the prism, b₁ and b₂ are the lengths of the parallel bases, and x and y are the lengths of the non-parallel sides.

Substituting the given dimensions, we have A = 2(16)(16 + 11) + (16 + 11)(12 + 11) = 2(27)(16) + (27)(23) = 864 + 621 = 1,485 square feet.

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]
