No, the number 21x09 is not equal to 22 00, correct to 2 significant figures. To determine the value of x if 21x09 is a perfect square, we need to consider its prime factorization.

The prime factorization of 21x09 is 3^2 * 7 * x * 13. For a number to be a perfect square, each prime factor must have an even exponent. Since 13 is the only prime factor with an odd exponent, we need to choose a value of x that cancels out the odd exponent of 13.

To achieve this, x must be a multiple of 13. Therefore, any value of x that is a multiple of 13 will make 21x09 a perfect square.

The recommended rule to sequence the jobs for minimum flow time is the EDD (Earliest Due Date) rule.

The EDD rule prioritizes jobs based on their due dates, where jobs with earlier due dates are given higher priority. By sequencing the jobs in order of their due dates, the goal is to minimize the total flow time, which is the sum of the time it takes to complete each job.

In this case, applying the EDD rule, the sequence of jobs would be as follows:

D (Due on Friday 10th June)

F (Due on Tuesday 14th June)

E (Due on Wednesday 15th June)

C (Due on Friday 17th June)

G (Due on Thursday 16th June)

H (Due on Saturday 18th June)

A (Due on Monday 13th June)

B (Due on Monday 20th June)

By following the EDD rule, we aim to complete the jobs with earlier due dates first, minimizing the flow time and ensuring timely delivery of the orders.

Therefore, the recommended rule for sequencing the jobs in this scenario is the EDD (Earliest Due Date) rule.

The y-intercept is (0, 1). a. the end behavior of the graph is that it behaves like y = 2x + 1 for large values of |x|. b. the y-intercept of the graph of the function is y = 1.

(a) The end behavior of the graph of the function is that it behaves like y = 2x + 1 for large values of |x|.

To determine the end behavior, we look at the highest degree term in the polynomial function, which is x. The coefficient of this term is 2, which is positive. This tells us that as x becomes very large in either the positive or negative direction, the function will also become very large in the positive direction. Therefore, the end behavior of the graph is that it behaves like y = 2x + 1 for large values of |x|.

(b) To find the x-intercepts of the graph of the function, we set f(x) = 0 and solve for x:

(x+4)-(3-x) = 0

2x + 1 = 0

x = -1/2

Therefore, the x-intercept of the graph of the function is x = -1/2.

To find the y-intercept of the graph of the function, we set x = 0 and evaluate f(x):

f(0) = (0+4)-(3-0) = 1

Therefore, the y-intercept of the graph of the function is y = 1.

No, not all square numbers have an odd number of factors. In fact, square numbers can have either an odd or an even number of factors, depending on their prime factorization.

A square number is a number that can be expressed as the product of an integer multiplied by itself. For example, 4 is a square number because it can be written as 2 * 2.

When we analyze the factors of a square number, we find that each factor has a corresponding pair that multiplies to give the square number. For instance, the factors of 4 are 1, 2, and 4. We can see that the pairs are (1, 4) and (2, 2). Thus, 4 has an even number of factors.

However, there are square numbers that have an odd number of factors. Consider the square number 9, which is equal to 3 * 3. The factors of 9 are 1, 3, and 9. In this case, 9 has an odd number of factors.

In conclusion, while some square numbers have an odd number of factors (like 9), others have an even number of factors (like 4). The determining factor is the prime factorization of the square number.

Answer:

There are 342 different combinations.

Step-by-step explanation:

Ok, Aileen is choosing toppings for a pizza.

She can choose two.

There are 19 options that can be chosen once.

The first thing we need to do, is find all the "selections".

Here we have two selections:

Topping number 1

Topping number 2.

Now we need to find the number of options for each one of these selections:

Topping number 1:  Here we have 19 options.

Topping number 2:  Here we have 18 options (because one was already taken in the previous selection)

The total number of combinations is equal to the product between the numbers of options.

C = 19*18 = 342

There are 342 different combinations.

The linearization of the function f(x,y) = √(x² + 16y²) is L(x,y) = 5 + 3(x-3)/5 + 16(x-1)/5 and the approximation of f(2.9.1.1) is 5.26.

The linearization of a function f(x,y) at the point (a,b) is given by,

L(x,y) = f(a,b) + fₓ(a,b)*(x - a) + fᵧ(a,b)*(y - b)

where fₓ and fᵧ are the partial derivatives of function 'f' with respect to 'x' and 'y' respectively.

Given the function is,

f(x,y) = √(x² + 16y²)

Now partially differentiate the above function firstly with respect to 'x' and then by 'y' we get,

fₓ(x,y) = (1/(2√(x² + 16y²)))*(2x) = x/√(x² + 16y²)

fᵧ(x,y) = (1/(2√(x² + 16y²)))*(32y) = 16y/√(x² + 16y²)

Given the point (a,b) = (3,1).

So substituting we get,

fₓ(3,1) = 3/√(9+16) = 3/√25 = 3/5

fᵧ(3,1) = 16/√(9+16) = 16/√25 = 16/5

f(3,1) = √(9 + 16) = √25 = 5

Then the linearization of the function f(x,y) = √(x² + 16y²) at the point (3,1) we get,

L(x,y) = f(a,b) + fₓ(a,b)*(x - a) + fᵧ(a,b)*(y - b)

L(x,y) = 5 + 3(x-3)/5 + 16(x-1)/5

Now approximating by this linear equation we get,

L(2.9, 1.1) = 5 + 3(2.9 - 3)/5 + 16(1.1 - 1)/5 = 5 - 0.3/5 + 1.6/5 = (25-0.3+1.6)/5 = 26.3/5 = 5.26

And

f(2.9, 1.1) = √((2.9)² + 16(1.1)²) = 5.27 (Rounding up to 2 decimal places)

So we can approximate using the linear function.

Hence, the linearization of the function is L(x,y) = 5 + 3(x-3)/5 + 16(x-1)/5 and the approximation of f(2.9.1.1) is 5.26.

The two distances are equal, which means the points (2, -8) and (0, -8) are symmetric about the axis of symmetry x = 1, or the vertex (1, -9).

What is the quadratic equation?

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

The vertex of a parabola in standard form, f(x) = a(x - h)² + k, is at the point (h, k).

We can rewrite the given equation, f(x) = x² - 2x - 8, in standard form by completing the square:

f(x) = x² - 2x - 8

= (x² - 2x + 1) - 1 - 8

= (x - 1)² - 9

So the vertex of the parabola is at the point (1, -9), where h = 1 is the x-coordinate of the vertex, and k = -9 is the y-coordinate of the vertex.

To verify that points (2, -8) and (0, -8) are symmetric about the vertex, we can calculate the axis of symmetry, which is x = h, or x = 1 in this case.

The distance between the vertex (1, -9) and the point (2, -8) is the same as the distance between the vertex and the point (0, -8), since these points have the same y-coordinate:

d((1, -9), (2, -8)) = d((1, -9), (0, -8))

Using the distance formula, we can calculate the left-hand side:

d((1, -9), (2, -8)) = √((2 - 1)² + (-8 - (-9))²)

= √(1 + 1)

= √(2)

Using the distance formula again, we can calculate the right-hand side:

d((1, -9), (0, -8)) = √((0 - 1)² + (-8 - (-9))²)

= √(1 + 1)

= √(2)

Hence, the two distances are equal, which means the points (2, -8) and (0, -8) are symmetric about the axis of symmetry x = 1, or the vertex (1, -9).

Answer: Rs. 6075

40500×(15/100)= 6075

Step-by-step explanation:

If the second and third cards have a spade then the probability that the first card drawn is a spade is 21.2%.

Probability can be described as a field of mathematics that determines how likely a thing is to happen. When there is uncertainty about the outcome of an event we consider the probabilities of certain results or outcomes.

There are a total of 13 spades in a deck of 52 playing cards. So if the second and third cards have spades then there are 11 spades remaining.

The formula for probability can be given as;

probability = number of favorable outcomes or events ÷ total number of outcomes or events

probability = 11 / 52 = 0.212

Converting it into percentage;

probability = 0.212 × 100 = 21.2%

Therefore, the probability that the first card drawn is a spade is calculated to be 21.2%.

Step-by-step explanation:

- Mean: 119.43- Median: 118.50- Mode: 110 - Count: 28

To find the mean, we add up all the values and divide by the number of observations. In this case, the sum of the values is 3342, and since there are 28 observations, the mean is 3342/28 = 119.43.

The median is the middle value when the data is arranged in ascending order. In this case, there are 28 observations, so the median is the average of the 14th and 15th values. When the data is ordered, the 14th value is 118 and the 15th value is 124. Therefore, the median is (118 + 124)/2 = 118.50.

The mode is the value that appears most frequently in the dataset. In this case, the value 110 appears three times, which is more than any other value. Hence, the mode is 110.

The count simply refers to the number of observations in the dataset, which is 28 in this case.

(b) The data is skewed right.

When data is symmetric, it means that the values are evenly distributed around the mean, resulting in a bell-shaped curve. In this case, the data is not symmetric. Looking at the dataset, we can observe that there are several smaller values on the left side, while the right side has a few larger values. This indicates a right skew or positive skewness.

Skewness refers to the asymmetry of a distribution. In a right-skewed distribution, the tail of the distribution extends towards the right, indicating a longer right tail. Therefore, the correct answer is b. Skewed right, indicating that the data is positively skewed.

Question 1

27x^6 = (3x^2)^3 which is one cube and y^3 is another cube

Therefore 27x^6+y^3 is a sum of two cubes.

It might help to think of it like A^3+B^3 where in this case A = 3x^2 and B = y.

----------------------------------------

Question 2

81 isn't a perfect cube since 81^(1/3) = 4.3267 approximately, which isn't a whole number. We need 81^(1/3) to be a whole number if we wanted 81 to be a perfect cube.

We don't even need to check b^15 since 81 being a non-perfect cube means the entire expression cannot be a sum of two cubes, nor a difference of cubes.

----------------------------------------

Question 3

64x^3 = (4x)^3 is a perfect cube

but 9z^9 is not a perfect cube

We can see this if we computed 9^(1/3) and the result is a non-whole number.

The answer here is the same as the previous question.

----------------------------------------

Question 4

36^(1/3) is not a whole number, so 36 isn't a perfect cube. By extension  36m^12 isn't a perfect cube either. The answer is the same as questions 2 and 3.

----------------------------------------

Question 5

1 is a perfect cube since 1 = 1^3

d^12 is a perfect cube because d^12 = (d^4)^3

Therefore, we have a difference of two cubes.

----------------------------------------

Question 6

729^(1/3) = 9 which rearranges to 9^3 = 729, showing 729 is a perfect cube.

However y^29 is not a perfect cube since the exponent 29 is not a multiple of 3.

The overall expression is "neither".

----------------------------------------

Question 7

343^(1/3) = 7 rearranges to 7^3 = 343, showing 343 is a perfect cube

y^6 is a perfect cube since (y^2)^3, i.e. the exponent 6 is a multiple of 3.

We have a difference of cubes.

----------------------------------------

Question 8

4 isn't a perfect cube since 4^(1/3) results in some decimal value that isn't a whole number. The entire expression is neither a sum nor difference of cubes.

----------------------------------------

Question 9

144^(1/3) isn't a whole number, so we get a similar result to problem 8.

Answer:

46 of the total vehicles are minivans

Step-by-step explanation:

Let the number of minivans be x

and the number of other types of vehicles be y

From the question,

Carla noticed that for every 2 minivans, there were 5 other types of vehicles.

This means the ratio of minivans to other types of vehicles is 2:5.

Therefore,

x:y = 2:5

We can then write that

x/y = 2/5

∴ 5x = 2y ...... (1)

Also from the question,

There are 161 total vehicles in the parking lot

That is

x + y = 161 ...... (2)

From equation (2), we can write that

y = 161 - x

Put this into equation (1)

5x = 2y

Then

5x = 2(161-x)

5x = 322 -2x

5x+2x = 322

7x = 322

x = 322/7

x = 46

Since x represent the number of minivans

Hence, 46 of the total vehicles are minivans.

You bought 8 stamps that cost 45 cents each and 2 stamps that cost 30 cents each.

Let's assume you bought x stamps that cost 45 cents each and y stamps that cost 30 cents each.

From the given information, we can create two equations:

The total number of stamps is 10: x + y = 10.

The total cost is $4.20: 45x + 30y = 420 (since the cost is given in cents).

Now we can solve this system of equations to find the values of x and y.

We can multiply the first equation by 30 to eliminate y:

30x + 30y = 300.

Now we have a system of equations:

30x + 30y = 300,

45x + 30y = 420.

Subtracting the first equation from the second equation, we get:

45x + 30y - (30x + 30y) = 420 - 300,

15x = 120,

x = 120/15,

x = 8.

Substituting the value of x back into the first equation:

8 + y = 10,

y = 10 - 8,

y = 2.

Therefore, you bought 8 stamps that cost 45 cents each and 2 stamps that cost 30 cents each.
