The composition of the two translation rules is:

(x, y) → (x - 1, y - 6)

What is a translation rule?

A translation rule is a mathematical description of how to move each point in a geometric shape by a fixed distance in a certain direction. It is used to describe a transformation called a translation, which moves a shape without changing its size, shape, or orientation.

To find the composition of the two translation rules, we apply the second rule first and then apply the first rule to the result.

Let's consider a point (x, y). Applying the second rule (x, y) → (x - 5, y - 5) gives us a new point:

(x - 5, y - 5)

Now we apply the first rule (x, y) → (x + 4, y - 1) to this new point:

(x - 5 + 4, y - 5 - 1)

Simplifying:

(x - 1, y - 6)

Therefore, the composition of the two translation rules is:

(x, y) → (x - 1, y - 6)

Answer:

chocolate = $1.25

soft drink = $1.85

Step-by-step explanation:

Given price of chocolate is c and price of soft drink is s

Olivia: 5c + 2s = 9.95

Taylor: 6c + 6s = 18.60

6c + 6s = 18.60

divided by 6, we have

c + s = 3.1

=> s = 3.1 - c

Substitute s = 3.1 - c into

5c + 2s = 9.95

5c + 2(3.1 - c) = 9.95

5c + 6.2 - 2c = 9.95

3c = 9.95 - 6.2

3c = 3.75

c = 3.75/3 = 1.25

s = 3.1 - c = 3.1 - 1.25 = 1.85

The area of the triangle with side lengths of 25 cm, 7 cm, and 15 cm is approximately 209.27 cm².

To calculate the area of a triangle with side lengths of 25 cm, 7 cm, and 15 cm, we can use Heron's formula, which is a formula for finding the area of a triangle when only the side lengths are known:

Area = √(s(s-a)(s-b)(s-c))

where s is the semi-perimeter of the triangle, and a, b, and c are the lengths of its sides. The semi-perimeter is half the sum of the three sides:

s = (a + b + c) / 2

Substituting the given values, we get:

s = (25 + 7 + 15) / 2 = 23.5

Now we can use Heron's formula to calculate the area:

Area = √(23.5(23.5-25)(23.5-7)(23.5-15))

= √(23.5 * (-1.5) * 16.5 * 8.5)

= √(43,822.5)

Therefore, the zeros of the function f(x) are x = 5 and x = -4.

A polynomial is a mathematical expression consisting of variables and coefficients, combined using the operations of addition, subtraction, multiplication, and non-negative integer exponents. It can have one or more terms, and the degree of a polynomial is the highest power of the variable in the expression.

Here,

To find the zeros of the function f(x) = x² - x - 20, we need to solve for x when f(x) = 0:

x² - x - 20 = 0

We can factor the left side of this equation as:

(x - 5)(x + 4) = 0

Using the zero product property, we know that the product of two factors is zero if and only if at least one of the factors is zero. Therefore, we can set each factor equal to zero and solve for x:

Therefore, the density of the drink is approximately 1.04 grams per cm³.

Volume is a measure of the amount of space occupied by a three-dimensional object or substance. It is the amount of space inside an object or container and is usually measured in cubic units such as cubic meters (m³), cubic centimeters (cm³), or cubic feet (ft³).

Given by the question.

To calculate the density of the drink, we need to first calculate the total mass of the drink, which is the sum of the masses of apple juice, fruit syrup, and sparkling water.

Mass of apple juice = volume of apple juice x density of apple juice = 35 cm³ x 1.04 g/cm³ = 36.4 g

Mass of fruit syrup = volume of fruit syrup x density of fruit syrup = 25 cm³ x 1.6 g/cm³ = 40 g

Mass of sparkling water = volume of sparkling water x density of sparkling water = 270 cm³ x 0.99 g/cm³ = 267.3 g

Total mass of the drink = mass of apple juice + mass of fruit syrup + mass of sparkling water

= 36.4 g + 40 g + 267.3 g

= 343.7 g

Now we can calculate the density of the drink by dividing the total mass by the volume of the drink:

Density of the drink = total mass of the drink / volume of the drink = 343.7 g / 330 cm³ = 1.04 g/cm³ (approx.)

The problem is asking us to find out how many ternary sequences of digits are there that are chosen from {0, 1, 2} of length twelve, and have exactly three 1's and two 0's.

Therefore, there will be a total of 7 digits (12 - 3 - 2 = 7) that could be 1 or 2. So, let's solve it in steps.

Step 1: The number of ways we can choose 3 positions out of 12 for 1s is C (12,3).

Step 2: The number of ways we can choose 2 positions out of 9 (because there are already 3 1s and 2 0s) for 0s is C (9,2).

Step 3: We have three digits left that can be either 1 or 2. So, there will be 2 options for each of these digits, and the total number of options will be

2 × 2 × 2 = 8.

Step 4: So, the total number of sequences will be obtained by multiplying the results of Steps 1, 2, and 3. i.e.

C (12,3) × C (9,2) × 8

⇒ ¹²C₃ × ⁹C₂ × 8

The solution to the given homogenous differential equation dy/dx = y² + x² / x^2 is y² = -x(y³ / 3 + Cy³ - 3Cx)

The given differential equation is: dy/dx = y² + x² / x^2

To solve this, we can first separate the variables by bringing all the y-terms on one side and all the x-terms on the other side:

(1/y²)dy = (x² / x² + y²)dx

Next, we can integrate both sides:

∫(1/y²)dy = ∫(x²/x² + y²)dx

Using the substitution u = y/x, we can simplify the integrals:

∫(1/y²)dy = ∫(1 + u²)dx

-1/y = x + (1/3)u³ + C

where C is the constant of integration.

Substituting back u = y/x, we get:

Answer:

The correct option is C. x=3, x=-2±√2/3.

Step-by-step explanation:

To find all the zeros of the polynomial function f(x) = 3x^3 - 5x^2 - 10x - 6, we can follow the steps outlined in the previous answer:

Write the polynomial function in descending order of degree: f(x) = 3x^3 - 5x^2 - 10x - 6.

Use the Rational Root Theorem to generate a list of possible rational zeros: ±1, ±2, ±3, ±6, ±(1/3), ±(2/3).

Use synthetic division to test each possible zero. We start with x = 1:

1 │ 3 -5 -10 -6

│ 3 -2 -12

└─────────────

3 -2 -12 -18

x = 1 is not a zero of the polynomial function.

We continue testing the remaining possible zeros:

-1 │ 3 -5 -10 -6

│ -3 8 2

└────────────

3 -8 -2 -4

x = -1 is not a zero of the polynomial function.

2 │ 3 -5 -10 -6

│ 6 2 -16

└─────────────

3 1 -8 -22

x = 2 is not a zero of the polynomial function.

-2 │ 3 -5 -10 -6

│ -6 22 -24

└────────────

3 -11 12 -30

x = -2 is not a zero of the polynomial function.

3 │ 3 -5 -10 -6

│ 9 12 6

└─────────────

3 4 2 0

Since the remainder is zero, we have found a zero of the polynomial function at x = 3.

We can use synthetic division to factor the polynomial function:

3x - 1

(x - 3)(3x^2 + 13x + 2)

Now we can solve for the remaining zeros of the polynomial function by factoring the quadratic equation using the quadratic formula or factoring by grouping. Either way, we find that the remaining zeros are approximately x = -4.87 and x = -0.435.

Therefore, the zeros of the polynomial function f(x) = 3x^3 - 5x^2 - 10x - 6 are x = -4.87, x = -0.435, and x = 3.

It's C because we found the zero x = 3 through synthetic division, and then we used the quadratic formula to find the other two zeros. The quadratic formula gave us two solutions, which we simplified to x = -2 + sqrt(2)/3 and x = -2 - sqrt(2)/3.

If we substitute these solutions back into the original polynomial function f(x), we get:

f(-2 + sqrt(2)/3) = 3(-2 + sqrt(2)/3)^3 - 5(-2 + sqrt(2)/3)^2 - 10(-2 + sqrt(2)/3) - 6

≈ 0

f(-2 - sqrt(2)/3) = 3(-2 - sqrt(2)/3)^3 - 5(-2 - sqrt(2)/3)^2 - 10(-2 - sqrt(2)/3) - 6

≈ 0

Both of these values are approximately zero, which means that -2 + sqrt(2)/3 and -2 - sqrt(2)/3 are also zeros of the polynomial function.

Therefore, the zeros of the polynomial function f(x) = 3x^3 - 5x^2 - 10x - 6 are x = 3, x = -2 + sqrt(2)/3, and x = -2 - sqrt(2)/3, which matches option C.

Answer:

The correct option is A. x = -1, x = 3, x = ±√5.

We found the zero x = -1 through synthetic division, and then we factored the cubic polynomial using the Rational Root Theorem and synthetic division to obtain (x + 1)(x^3 - 3x^2 - 6x + 15). We found that the remaining zeros of the polynomial function are the roots of the quadratic factor x^2 - 3x - 5, which are x = (3 ± √29))/2.

Therefore, the zeros of the polynomial function f(x) = x^4 - 2x^3 - 8x^2 + 10x + 15 are x = -1, x = 3, x = (3 + √(29))/2, and x = (3 - √(29))/2, which simplifies to x = (3 ± √(5))/2.

Option A lists all of these zeros, so it is the correct option. Options B and C do not list all of the zeros of the polynomial function.

STEPS: Here are the steps to find all the zeros of the polynomial function f(x) = x^4 - 2x^3 - 8x^2 + 10x + 15:

Write the polynomial function in descending order of degree: f(x) = x^4 - 2x^3 - 8x^2 + 10x + 15.

Use the Rational Root Theorem to generate a list of possible rational zeros: ±1, ±3, ±5, ±15.

-1 │ 1 -2 -8 10 15

│ -1 3 -5 -5

└───────────────

x = -1 is a zero of the polynomial function. We can write f(x) as:

f(x) = (x + 1)(x^3 - 3x^2 - 5x + 10)

Use the Rational Root Theorem and synthetic division to factor the cubic equation x^3 - 3x^2 - 5x + 10:

x = -3 is not a zero of the polynomial function.

The only remaining possible rational zeros are ±1/1 and ±5/1, but testing these values using synthetic division does not yield any more zeros.

Solve for the remaining zeros of the polynomial function by factoring the quadratic equation x^2 - 3x - 5 using the quadratic formula or factoring by grouping:

x = (3 ± √(29))/2

These are the remaining zeros of the polynomial function.

Therefore, the zeros of the polynomial function f(x) = x^4 - 2x^3 - 8x^2 + 10x + 15 are x = -1, x = 3, x = (3 + √(29))/2, and x = (3 - √(29))/2, which simplifies to x = (3 ± √(5))/2.

Option A lists all of these zeros, so it is the correct option.

Julie is trekking to the Blue Ridge Mountains, therefore she is 10 1/12 miles from the beginning point M.

Distance in mathematics is a numerical representation of the actual area between two points. The shortest distance between those two points is how long the path is. The Pythagorean theorem, which asserts that in a right triangle, the sum of the squares of the lengths of the two legs (the sides perpendicular to one another) is equal to the square of the length of the hypotenuse, is used to determine the distance between two locations in a two-dimensional plane (the longest side, opposite the right angle).

given

We must determine Julie's total distance traveled before we can determine how far she is from the beginning location M. By combining the distances between each location, we may determine this:

3 3/8 miles from M to N

2 1/4 miles from N to P

P returning to M: 4 11/24 miles

We must identify a common denominator in order to aggregate these distances. Because it can be divided by 8, 4, and 3, we may pick 24 as the common denominator.

From M to N, the distance is 3 3/8 miles (or 27/8 kilometers). From N to P, it is 2 1/4 kilometers (or 9 kilometers).

We may now multiply the distances:

27/8 + 9/4 + 107/24 = (81 + 54 + 107) / 24

= 242/24

= 10 1/12

Julie is trekking to the Blue Ridge Mountains, therefore she is 10 1/12 miles from the beginning point M.

The discounted price of the camera is $270 and the price of the camera after the 40% increase is $378.

When the store offered a 40% discount on the original price of $450, the discounted price of the camera can be calculated as follows:

Discounted price = Original price - Discount

Discounted price = $450 - 40% x $450

Discounted price = $450 - $180

Discounted price = $270

Therefore, the discounted price of the camera is $270.

After the sale, the discounted price of the camera was increased by 40%. We can calculate the new price of the camera as follows:

New price = Discounted price + 40% x Discounted price

New price = $270 + 40% x $270

New price = $270 + $108

New price = $378

By speed formula, it would take Franklin 2 hours and 30 minutes (or 150 minutes) to shovel the driveway alone.

What is speed?

Speed is defined as the distance travelled by an object in a given amount of time. Speed is a scalar quantity, meaning that it has magnitude but no direction.

Mathematically, speed is calculated as follows:

speed = distance / time

where "distance" is the distance travelled by the object, and "time" is the time it takes for the object to travel that distance.

Let's assume that Angela's shoveling rate is "a" and Franklin's shoveling rate is "f" (measured in driveways per hour). We can use the formula:

time = distance / rate

where "distance" is the length of the driveway (which we can assume to be 1 driveway) and "rate" is the shoveling rate (in driveways per hour).

According to the problem, Angela can shovel the driveway in 2 hours, so her shoveling rate is:

a = 1/2

When Franklin joins her, they can finish the driveway in 54 minutes, or 9/10 of an hour. Therefore, their combined shoveling rate is:

(a + f) = 1 / (9/10) = 10/9

We can now set up a system of equations to solve for "f".

First, we know that Angela and Franklin can finish the driveway in 9/10 of an hour:

1/2 + f = 1 / (9/10)

Multiplying both sides by 10/9, we get:

5/9 + (10/9)f = 1

Simplifying, we get:

(10/9)f = 4/9

f = (4/9) * (9/10)

f = 4/10

f = 2/5

Therefore, Franklin's shoveling rate is 2/5 of a driveway per hour. To find how long it would take him to shovel the driveway alone, we can use the formula:

time = distance/rate

time = 1 / (2/5)

time = 5/2

time = 2 1/2 hours

Therefore, it would take Franklin 2 hours and 30 minutes (or 150 minutes) to shovel the driveway alone.

If a lorry travels 320km and uses 40 litres of petrol, the average rate of petrol usage for the lorry is 8 km per liter.

To find the average rate of petrol usage for the lorry, we need to divide the total distance traveled by the amount of petrol used. This will give us the number of kilometers traveled per liter of petrol.

In this case, the lorry traveled 320 km and used 40 liters of petrol, so we can calculate the average rate of petrol usage as follows:

Average rate of petrol usage = Total distance traveled / Amount of petrol used

= 320 km / 40 litres

= 8 km/litre

This means that for every liter of petrol used, the lorry can travel an average of 8 kilometers. This metric can be useful in comparing the fuel efficiency of different vehicles or in calculating the cost of a particular journey based on the price of petrol per liter.
