∛108c¹⁷ =  ∛2*2*3*3*3*3*c¹⁵ *c²

= 3c⁵∛4c²

Hint: c¹⁵ = (c⁵)³ = c⁵ * c⁵ *c⁵

Answer: x = 3

Step-by-step explanation: To solve for x in this equation, we must first isolate the term containing x which in this problem is -3x. Since 2 is being added to -3x, we subtract 2 from both sides of the equation to isolate the -3x.

On the left, the +2 and -2 cancel out and on the right -7 - 2 is -9 so we have -3x = -9. Now we can finish things off by just dividing both sides of the equation by -3. On the left the -3's cancel and on the right, -9 divided by -3 simplifies to 3. So we have x = 3.

Final answer:

The ratio of legs to ears for Santa's reindeer is 2 legs/ear.

Explanation:

The question is asking for the ratio of legs to ears as it relates to Santa's reindeer. We know that Santa has 9 reindeer and reindeer typically have 4 legs and 2 ears. So the total number of legs would be 9 reindeer * 4 legs/reindeer = 36 legs. And the total number of ears would be 9 reindeer * 2 ears/reindeer = 18 ears. To find the ratio of legs to ears, we divide the number of legs by the number of ears: 36 legs / 18 ears = 2 legs/ear.

There are approximately 275.59 inches in 7 meters.

To find out how many inches are in 7 meters, we will first convert meters to centimeters, and then centimeters to inches.

Since there are 100 centimeters in one meter, we can calculate:

7 meters × 100 centimeters/meter = 700 centimeters

Now, we know there are 2.54 centimeters in one inch, we can convert the 700 centimeters to inches:

700 centimeters × 1 inch/2.54 centimeters ≈ 275.59 inches

To the nearest inch, there are approximately 275.59 inches in 7 meters.

Answer:

Options A, B, and D are correct.

Step-by-step explanation:

The given function is p(x) = x³ - 6x² - x + 30

Given that p(5) = 0, p(3) = 0 and p(-2) = 0

Therefore, putting x = 5, or x = 3, or x = -2, the function p(x) vanishes to zero.

Therefore, those are the roots of the given function p(x).

Hence, we can conclude that (x - 5), (x - 3) and (x + 2) are the factors of the function p(x) = x³ - 6x² - x + 30.

So, options A, B, and D are correct. (Answer)

Answer:

Explanation:

1. Cost of each liter of yellow paint:

Yellow paint is sold in 5 litre tins and ach tin costs £26, thus the cost of one liter is £26 / 5 liters = £5.2 per liter.

2. Cost of each liter of blue paint:

Blue paint is sold in 10 litre tins and each tin costs £48, thus the cost of one liter of blue paint is £48 / 10 liters = £4.8 per liter

3. Cost of each liter of green paint.

Green paint is made by mixing yellow paint and blue paint in the ratio 2:3

Thus, 5 liters of green paint will cost:

2 liters yellow paint: 2 liter × £5.2 / liter = £10.4

3 liters blue paint:     3 liter × £4.8 / liter = £14.4

                                 ==========              ========

5 liters green paint:   5 liter                        £24.8

Cost of one liter of gree paint: £24.8 / 5 liter = £4.96 / liter

4. Profit

Price of each liter of green paint: £66.96 / 10 liters = £6.696 / liter = £6.70 / liter

Profit per liter = price per liter - cost per liter = £6.70/liter - £4.96 / liter = £1.74 / liter

Percentage profit = profit per liter / cost per liter × 100

Percentage profit = (£1.74 / liter) / (£4.96/liter) × 100 =  35.08% = 35%

Answer:

The number of footballs, basketballs and volleyballs were sold are 75, 36 and 15 respectively.

Step-by-step explanation:

Consider the provided information.

A football costs $35, a basketball costs $25  and a volleyball costs $15.

Let F represents the football, B represents the basketball and V represents the volleyball.

On a given day, the store sold 5 times as many footballs as volleyballs.

[tex]F=5V[/tex]......(1)

They  brought in a total of $3750 that day,

[tex]35F+25B+15V=3750[/tex]......(2)

The money made from basketballs alone was 4 times the money.

[tex]25B=4(15V)[/tex]......(3)

By equation 1, 2 and 3.

[tex]35(5V)+4(15V)+15V=3750[/tex]

[tex]250V=3750[/tex]

[tex]V=15[/tex]

Substitute the value of V in equation 1 and 3.

[tex]F=5(15)=75[/tex]

[tex]25B=4(15\times 15)\\B=36[/tex]

Hence, the number of footballs, basketballs and volleyballs were sold are 75, 36 and 15 respectively.

The system of equations is as follows:

35F + 25B + 15V = 3750

1 F = 5V

25B = 60V

Let's define the variables first:

We are given the following information:

We can write the system of equations as:

35F + 25B + 15V = 3750

F = 5V

25B = 60V

Complete question:

A sporting goods store sells footballs (F), basketballs (B), and volleyballs (V). A football sells for $35 a basketball sells for $25, and a volleyball sells for $15. On a given day, the store sold 5 times as many footballs as volleyballs. The sales brought in a total of $3750 that day, and the money made from basketballs alone was four times the money made from volleyballs. Write the system of equations to determine how many of each type of ball were sold by entering relevant numbers in the boxes provided below to complete each equation. Do not solve the system.

___ F + ___ B + ___ V = 3750

Answer: OPTION B.

Step-by-step explanation:

Below are shown some transformations for a function f(x):

1) If [tex]f(x)+k[/tex], the function is shifted up "k" units.

2) If [tex]f(x)-k[/tex], the function is shifted down "k" units.

In this case you have the following function, which you can call f(x):

[tex]y =f(x)= x^2 + 2[/tex]

Based on the transformations explained before, if this function is shifted down 4 units, you know that function obtained g(x) is:

[tex]g(x)= x^2 + 2-4\\\\g(x)= x^2 -2[/tex]

Therefore, the equation that will shift the graph of the function down 4 units, is:

[tex]y= x^2 -2[/tex]

Answer:The remainder can be calculated by doing the following steps;

Step-by-step explanation:

The remainder when f(x) = x⁴ - 5x³ + 3x² - 2x +7 is divided by x - 1 is 4.

Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.

The remainder theorem states that when a polynomial, f(x), is divided by a linear polynomial , x - a, the remainder of that division will be equivalent to f(a).

Given that f(x) = x⁴ - 5x³ + 3x² - 2x +7 is divided by x - 1

x - 1 = 0

x = 1

f(1) = 1⁴ - 5(1)³ + 3(1)² - 2(1) + 7 = 4

The remainder when f(x) = x⁴ - 5x³ + 3x² - 2x +7 is divided by x - 1 is 4.

Answer: 2/3

Step-by-step explanation: We can rewrite the ratio 6 out of 9 as the fraction 6/9 by putting 6 in the position of the numerator and 9 in the position of the denominator.

Notice however, 6/9 is not in lowest terms so we need to divide the numerator and the denominator by the greatest common factor of 6 and 9 which is 3 to get the equivalent fraction 2/3.

Therefore, the ratio 6 out of 9 can be rewritten as the fraction 2/3.

Answer:

The Cardboard dimensions are 13cm in length and 12cm in breadth

Step-by-step explanation:

We can use Pythagoras Theorem to find the length the Cardboard (a²+b²=c²). Let A be 5 and B be 12, we find that C is equivalent to 13. The height is 12, thus the breadth of the Cardboard is also 12. Hope this helps :)

Final answer:

The dimensions of the cardboard rectangle are 5 cm by 12√2 cm.

Explanation:

To determine the dimensions of the cardboard rectangle inserted diagonally into a box with given dimensions, we first need to calculate the diagonal of the box that lies in the length-height plane. The box is 12 cm long and 12 cm high.

By using the Pythagorean theorem, we can find the length of the diagonal 'd' using the formula √(l² + h²), where 'l' is the length of the box and 'h' is the height.

In this case, 'd' = √(12² + 12²) = √(144 + 144) = √(288) = 12√2 cm.

Thus, the dimensions of the cardboard rectangle are its width, which is 5 cm (the width of the box), and its diagonal, which is 12√2 cm.
