Part B: The cost of the coffee is $2.83.

Part C: The height of the container is 9cm.

Part D: The cost of the hot chocolate powder is $49.35.

What is volume of cylinder ?

The volume of a cylinder is the amount of space occupied by a cylindrical shape. It is given by the formula:

V = πr²h

where V is the volume, r is the radius of the circular base of the cylinder, and h is the height of the cylinder. The formula is derived by multiplying the area of the circular base (πr²) by the height (h) of the cylinder.

According to the question:
Part A:

Given that the container is a cylinder with a radius of 3cm, we can use the formula for the volume of a cylinder to find the height of the container. The formula for the volume of a cylinder is:

V = πr²h

where V is the volume of the cylinder, r is the radius of the cylinder, and h is the height of the cylinder.

Substituting the given values, we get:

45π = π(3)²h

Simplifying and solving for h, we get:

h = 5

Therefore, the height of the container is 5cm.

Part B:

The volume of the container is 45π cm³ and the cost of coffee is $0.02 per cubic centimeter. Therefore, the total cost of the coffee is:

Total cost = Volume x Cost per unit volume

Total cost = 45π x $0.02

Total cost = $0.90π

Rounding to two decimal places, we get:

Total cost = $2.83

Therefore, the cost of the coffee is $2.83.

Part C:

Given that the container is a cylinder with a radius of 5cm, we can use the same formula for the volume of a cylinder to find the height of the container. Substituting the given values, we get:

225π = π(5)²h

Simplifying and solving for h, we get:

h = 9

Therefore, the height of the container is 9cm.

Part D:

The volume of the container is 225π cm³ and the cost of hot chocolate powder is $0.07 per cubic centimeter. Therefore, the total cost of the hot chocolate powder is:

Total cost = Volume x Cost per unit volume

Total cost = 225π x $0.07

Total cost = $15.75π

Rounding to two decimal places, we get:

Total cost = $49.35

Therefore, the cost of the hot chocolate powder is $49.35.

The final answer in quotient and remainder form is:

(x^(2)+4x-20)÷(x-4) = x+8 with a remainder of 12

To determine the quotient and remainder of the given expression, we can use synthetic division. Synthetic division is a method of dividing a polynomial by a linear factor in the form of x-a. In this case, the linear factor is x-4, so a=4.

Here are the steps for synthetic division:

Write the coefficients of the dividend, x^(2)+4x-20, in a row: 1 4 -20
Write the value of a, 4, to the left of the coefficients.
Bring down the first coefficient, 1, to the bottom row.
Multiply the value in the bottom row by a, 4, and write the result, 4, in the second column of the top row.
Add the numbers in the second column of the top row, 4+4, and write the result, 8, in the bottom row.
Multiply the value in the bottom row by a, 4, and write the result, 32, in the third column of the top row.
Add the numbers in the third column of the top row, -20+32, and write the result, 12, in the bottom row.

The bottom row now contains the coefficients of the quotient, 1 and 8, and the remainder, 12. So the quotient is x+8 and the remainder is 12.

The final answer in synthetic division form is:

4 | 1  4  -20
 |    4   32
 -------------
 | 1  8   12

The final answer in quotient and remainder form is:

(x^(2)+4x-20)÷(x-4) = x+8 with a remainder of 12

So the quotient is x+8 and the remainder is 12.

The distribution of Sn + Tm is a binomial distribution with parameters (n+m, p).

This can be proved using the fact that the sum of independent binomial random variables follows a binomial distribution with the sum of the number of trials and the same probability of success.



Let X ~ Binomial(n, p) and Y ~ Binomial(m, p) be independent random variables representing the number of heads in the first n coin tosses and the last m coin tosses, respectively.

Then, the sum of X and Y, Z = X + Y, follows a binomial distribution with parameters (n+m, p).

The probability mass function of Z can be written as:

P(Z = k) = P(X + Y = k) = ∑ P(X = i) * P(Y = k-i) for i = 0 to k

Since X and Y are independent, we can write:

P(Z = k) = ∑ P(X = i) * P(Y = k-i) = ∑ (n choose i) * p^i * (1-p)^(n-i) * (m choose k-i) * p^(k-i) * (1-p)^(m-k+i)

Simplifying the above equation, we get:

P(Z = k) = (n+m choose k) * p^k * (1-p)^(n+m-k)

Therefore, Z ~ Binomial(n+m, p).

As a result, the distribution of Sn + Tm has the parameters (n+m, p) of a binomial distribution.

Step-by-step explanation:

Since, 13 is not less than 13. Therefore, x = 5 is not a solution to the inequality 13 < 2x+3.

To determine whether a value of x is a solution to the inequality 13 < 2x+3, we need to substitute the value of x into the inequality and see if it is true or false.

Let's try x = 5. Then: 13 < 2x+3

13 < 2(5)+3

13 < 10+3

13 < 13

This is not true, since 13 is not less than 13. Therefore, x = 5 is not a solution to the inequality 13 < 2x+3.

Note that if we had found 13 < 13 instead, then we would have concluded that x = 5 is not a solution to the inequality. But since the inequality is strict (i.e., "less than"), we need to have a strict inequality when we substitute the value of x to determine whether it is a solution.

Answer:

Smaller number = 19

Larger number = 71

x + y = 90

x = 14 + 3y

Step-by-step explanation:

Let y represent the smaller number, and then represent the larger number as x, in terms of y:

Smaller number = y

Larger number = x = 3y + 14

Since the sum of the two numbers is 90, form an equation by adding them together in this notation:

y + 3y + 14 = 90

Simplify the equation:

4y + 14 = 90

4y = 76

y = 19

Therefore the smaller number is 19. Now substitute into the expression for the larger number to find its value:

x = 3(19) + 14 = 71

Now verify the two values sum to 90 like we expect:

19 + 71 = 90

Now we can use what we know to complete the equations, if x = 71:

x + y = 90 (we know they sum to 90)

x = 14 + 3y (as respresented above - multiplying by 3 and adding 14)

The average rate of change for the week is calculated by subtracting the first day's attendance (1,534) from the last day's attendance (2,394) and then dividing by the number of days (7).

Number is an abstract concept used to describe a quantity or amount of something. It is used to measure, count, and label objects, people, places, and other things. Numbers can be used to describe size, shape, location, and many other concepts. They are also used to represent data, money, and other mathematical operations. Numbers are the cornerstone of mathematics, and they are used in a variety of ways in everyday life.

This yields an average rate of change of +77.71 people per day.

This average rate of change is only a good measure for how the number of people changed throughout the week if the number of people changed in a consistent manner. If the attendance was relatively stable from day to day, then the average rate of change would accurately reflect the number of people who attended. However, if the attendance changed drastically from day to day, the average rate of change would not accurately reflect the attendance for the entire week.

The determinant of matrix A is -6.

A. To evaluate det(A) by a cofactor expansion along a row or column of your choice, we can choose any row or column and multiply each element by its corresponding minor and sign.

For example, let's choose the first row:

det(A) = (-6)(4*3-0*1) + (0)(2*3-(-1)*2) + (2)(2*0-(-1)*4)

det(A) = (-6)(12) + (0)(6) + (2)(4)

det(A) = (-72) + (0) + (8)

det(A) = -64

Therefore, the determinant of matrix A is -64.

B. Alternatively, we could have chosen any other row or column and the result would have been the same. For example, if we chose the third column:

det(A) = (2)(4*0-2*0) + (-1)(-6*3-2*0) + (3)(-6*0-2*4)

det(A) = (2)(0) + (-1)(-18) + (3)(-8)

det(A) = (0) + (18) + (-24)

det(A) = -6

Therefore, the determinant of matrix A is -6.

A function is a mathematical rule that takes an input value and produces a unique output value. It can be thought of as a machine that transforms input values into output values.

The domain of the piecewise function g of x is (–∞, 2) ∪ (2, ∞), since the expression x squared plus 2 times x minus 8 is equal to zero when x is equal to negative 4 and 2, but the function is undefined at x equals negative 4 and x equals negative 5 due to the logarithmic function.

For part (a), the answer is f(x+h) = x² + 2xh + h² - 4x - 4h. for par (b) h = -x ± sqrt(x² + 6), the value of h depends on the value of x

(a) To find f(x+h), we substitute x+h for x in the expression for f(x):

f(x+h) = (x+h)² - 4(x+h)

Expanding the square and simplifying, we get:

f(x+h) = x² + 2xh + h² - 4x - 4h

(b) To find h, we start with the expression for f(x+h) that we found in part (a):

f(x+h) = x² + 2xh + h² - 4x - 4h

We want to simplify this expression so that we can identify h. To do this, we start by subtracting f(x) from both sides:

f(x+h) - f(x) = (x² + 2xh + h² - 4x - 4h) - (x² - 4x)

Simplifying, we get:

f(x+h) - f(x) = 2xh + h² - 4h

Now we can identify h by setting this expression equal to some value and solving for h. For example, if we set f(x+h) - f(x) equal to 5, we get:

2xh + h² - 4h = 5

Simplifying and rearranging, we get a quadratic equation in h:

h² + 2xh - 4h - 5 = 0

We can solve this using the quadratic formula:

h = (-2x ± √(4x² + 24))/2

Simplifying, we get:

h = -x ± √(x² + 6)

Answer:

To create a perfect-square binomial of the form (y - k)^2, we need to find the value of k such that:

the first term of the binomial is y^2 (which is already the case)

the second term of the binomial is -2ky (which corresponds to -36y in the given expression)

the third term of the binomial is k^2 (which corresponds to 81 in the given expression)

To find k, we can use the formula:

k = (1/2)*(-b/a)

where a is the coefficient of y^2, b is the coefficient of y, and we are looking for the value of k that makes the expression a perfect square.

In this case, a = 1 and b = -36, so:

k = (1/2)(-b/a) = (1/2)(-(-36)/1) = 18

Therefore, the missing number to create a perfect-square binomial is 18:

(y - 18)^2 = y^2 - 36y + 324

A linear transformation is a function that takes two input values and returns two output values in a way that preserves the linear structure of the data. It is described by a matrix that determines the output values from the input values. In the case of \(T_{1}\) and \(T_{2}\), the matrix is

According to the given information product of (3x - 2) and (2z + 6) is 6xz + 18x - 4z - 12.

In mathematics, expressions are also combinations of constants, variables, operators, and function calls that represent mathematical operations or relationships.

Let's start with distributing the first term of the first expression to both terms of the second expression, then distributing the second term of the first expression to both terms of the second expression:

(3x - 2)(2z + 6)

= 3x(2z + 6) - 2(2z + 6)

= 6xz + 18x - 4z - 12

Now, let's use the FOIL method to find the same product:

(3x - 2)(2z + 6)

= 3x(2z) + 3x(6) - 2(2z) - 2(6)

= 6xz + 18x - 4z - 12

As you can see, both methods result in the same product: 6xz + 18x - 4z - 12.

Therefore, according to the given information product of (3x - 2) and (2z + 6) is 6xz + 18x - 4z - 12.

Answer:

132.7cm²

Step-by-step explanation:

area of circle =  πr²

6.5² * π

=132.7cm²

16. The expression of the product as a sum: 7 cos(6x)cos(7x) = 7/2 * (cos(13x) + cos(x))
17. The expression of the sum as a product: sin(2x) - sin(7x) = -2 cos(9x/2) sin(5x/2)

The product as a sum can be written using the formula for the product of two cosines:

cos a * cos b = 1/2 * (cos(a + b) + cos(a - b))

Using this formula, we can write the product 7 cos(6x)cos(7x) as a sum:

7 cos(6x)cos(7x) = 7/2 * (cos(6x + 7x) + cos(6x - 7x))
= 7/2 * (cos(13x) + cos(-x))
= 7/2 * (cos(13x) + cos(x))


The sum as a product can be written using the formula for the difference of two sines:

sin a - sin b = 2 cos((a + b)/2) sin((a - b)/2)

Using this formula, we can write the sum sin(2x) - sin(7x) as a product:

sin(2x) - sin(7x) = 2 cos((2x + 7x)/2) sin((2x - 7x)/2)
= 2 cos(9x/2) sin(-5x/2)
= 2 cos(9x/2) (-sin(5x/2))
= -2 cos(9x/2) sin(5x/2)

So the final answers are:
7 cos(6x)cos(7x) = 7/2 * (cos(13x) + cos(x))
sin(2x) - sin(7x) = -2 cos(9x/2) sin(5x/2)
